Performance Evaluation of Recycled Fibers in Asphalt Mixtures

This study presents the results of using innovative and sustainable recycled fibers in different asphalt mixtures. Laboratory design and performance evaluation were focused on the cracking and rutting resistance of asphalt mixtures reinforced with recycled fibers. Two mixtures were designed for this research: 1. A dense-graded hot-mix asphalt (HMA) mixture containing 15% reclaimed asphalt pavement (RAP) and a PG 64-22 asphalt binder. 2. A cold-recycled mixture (CRM) incorporating silica fume and Portland cement as a mineral filler and CSS-1H asphalt emulsion. The recycled fibers used in this study included PET, LDPE, and carbon and rubber fibers. A balanced mix design (BMD) approach based on cracking and rutting performance parameters was used to design the control mixtures. The IDEAL-CT (ASTM D8225) was conducted to assess the cracking resistance, and the IDEAL-RT (ASTM D8360) was applied for rutting resistance. For the HMA mixture, results showed that the addition of PET, carbon, and rubber fibers enhanced cracking resistance and influenced the rutting resistance; ANOVA analyses revealed statistically significant differences in both CT index and RT index between the control mixture and the fiber-reinforced mixtures. In the case of the cold-recycled mixtures, the addition of LDPE, PET, and rubber improved cracking resistance; however, a decrease in rutting resistance was also observed among the evaluated CRM samples.

Synthesis and Degradation of the Phytohormone Indole-3-Acetic Acid by the Versatile Bacterium Paraburkholderia xenovorans LB400 and Its Growth Promotion of Nicotiana tabacum Plant

Plant growth-promoting bacteria (PGPB) play a role in stimulating plant growth through mechanisms such as the synthesis of the phytohormone indole-3-acetic acid (IAA). The aims of this study were the characterization of IAA synthesis and degradation by the model aromatic-degrading bacterium Paraburkholderia xenovorans LB400, and its growth promotion of the Nicotiana tabacum plant. Strain LB400 was able to synthesize IAA (measured by HPLC) during growth in the presence of tryptophan and at least one additional carbon source; synthesis of anthranilic acid was also observed. RT-PCR analysis indicates that under these conditions, strain LB400 expressed the ipdC gene, which encodes indole-3-pyruvate decarboxylase, suggesting that IAA biosynthesis proceeds through the indole-3-pyruvate pathway. In addition, strain LB400 degraded IAA and grew on IAA as a sole carbon and energy source. Strain LB400 expressed the iacC and catA genes, which encode the α subunit of the aromatic-ring-hydroxylating dioxygenase in the IAA catabolic pathway and the catechol 1,2-dioxygenase, respectively, which may suggest a peripheral IAA pathway leading to the central catechol pathway. Notably, P. xenovorans LB400 promoted the growth of tobacco seedlings, increasing the number and the length of the roots. In conclusion, this study indicates that the versatile bacterium P. xenovorans LB400 is a PGPB.

Comparison of the nutrient composition of sludge under aerobic and anaerobic mineralization from African catfish, Clarias gariepinus (Actinopterygii: Siluriformes: Clariidae), reared in an intensive recirculating aquaculture system

One of the major challenges in an intensive recirculating aquaculture system (RAS) is the sustainable management of fish sludge. The sludge contains a significant amount of nutrients that can be utilized by hydroponically grown crops in an integrated system called aquaponics. While this system has promising results, techniques to maximize nutrient recovery still need to be developed. African catfish, Clarias gariepinus (Burchell, 1822), can be stocked at very high densities, therefore it produces a substantial amount of sludge. In this study, sludge from African catfish RAS was subjected to different mineralization treatments (T1: anaerobic, T2: aerobic, and T3: aerobic with carbon addition) for nutrient recovery. The supernatant in T3 after mineralization had a statistically significant difference (P > 0.05) in their concentrations of N (2700 mg ∙ L–1), P (100 mg ∙ L–1), K (720 mg ∙ L–1), Ca (12 115.6 mg ∙ L–1), and Mg (3391.9 mg ∙ L–1) after 15 days, among the other mineralization methods and untreated sludge. It was then followed by the nutrient recovery performance of T2 and lastly, T1. Moreover, the low pH and warm temperature were observed to improve the solubilization of the nutrients, resulting in a higher nutrient recovery in T3. Hence, among the three mineralization treatments, T3 had the most potential to recover maximum nutrients from African catfish sludge to be used as organic fertilizer for hydroponically grown crops.

Freckle Formation Tendency of a Single-Crystal Nickel-based Superalloy with Minor Carbon Additions

Catabolic pathway acquisition by rhizosphere bacteria readily enables growth with a root exudate component but does not affect root colonization.

Horizontal gene transfer (HGT) is a fundamental evolutionary process that plays a key role in bacterial evolution. The likelihood of a successful transfer event is expected to depend on the precise balance of costs and benefits resulting from pathway acquisition. Most experimental analyses of HGT have focused on phenotypes that have large fitness benefits under appropriate selective conditions, such as antibiotic resistance. However, many examples of HGT involve phenotypes that are predicted to provide smaller benefits, such as the ability to catabolize additional carbon sources. We have experimentally simulated the consequences of one such HGT event in the laboratory, studying the effects of transferring a pathway for catabolism of the plant-derived aromatic compound salicyl alcohol between rhizosphere isolates from the Pseudomonas genus. We find that pathway acquisition enables rapid catabolism of salicyl alcohol with only minor disruptions to the existing metabolic and regulatory networks of the new host. However, this new catabolic potential does not confer a measurable fitness advantage during competitive growth in the rhizosphere. We conclude that the phenotype of salicyl alcohol catabolism is readily transferable but is selectively neutral under environmentally relevant conditions. We propose that this condition is common and that HGT of many pathways will be self-limiting because the selective benefits are small.IMPORTANCEHorizontal gene transfer (HGT) is a key process in microbial evolution, but the factors limiting HGT are poorly understood. Aside from the rather unique scenario of antibiotic resistance, the evolutionary benefits of pathway acquisition are still unclear. To experimentally test the effects of pathway acquisition, we transferred a pathway for catabolism of a plant-derived aromatic compound between soil bacteria isolated from the roots of poplar trees and determined the resulting phenotypic and fitness effects. We found that pathway acquisition allowed bacteria to grow using the plant-derived compound in the laboratory, but that this new phenotype did not provide an advantage when the bacteria were reinoculated onto plant roots. These results suggest that the benefits of pathway acquisition may be small when measured under ecologically-relevant conditions. From an engineering perspective, efforts to alter microbial community composition in situ by manipulating catabolic pathways or nutrient availability will be challenging when gaining access to a new niche does not provide a benefit.

Improving fracture toughness and densification behavior of single‐phase TaC–HfC ceramic with carbon additives

AbstractThis investigation was undertaken to determine the role of carbon additives on the densification behavior and fracture toughness of TaC–HfC ceramic. The composition of TaC‐19 vol% HfC‐5 vol% VC with 10 vol% nano graphite/10 vol% nano carbon black was sintered by hot‐pressing (HP) method. Also, the sintering temperature varied from 1700°C to 2000°C. Vanadium carbide was used as a sintering aid to minimize the porosity for the given hot‐pressing temperatures while keeping the consolidation temperature low. The analysis of XRD patterns revealed that the sintering process led to the formation of a ternary solid solution in the samples accompanied by the entire consumption of HfC and VC phases. Also, the presence of carbon additives increased the relative density from 96% to 100% by enhancing the sintering temperature from 1700°C to 2000°C. It was significantly higher than the carbon‐free sample, which had a maximum value of 96.7% at 2000°C. The results also indicated that the maximum fracture toughness of 7.1 MPa.m1/2 was obtained for nano carbon black contained samples at the sintering temperature of 1900°C and above. The toughening mechanisms in samples were discussed, too.

High-efficiency leaching process for selective leaching of lithium from spent lithium iron phosphate

With the arrival of the scrapping wave of lithium iron phosphate (LiFePO4) batteries, a green and effective solution for recycling these waste batteries is urgently required. Reasonable recycling of spent LiFePO4 (SLFP) batteries is critical for resource recovery and environmental preservation. In this study, mild and efficient, highly selective leaching of lithium from spent lithium iron phosphate was achieved using potassium pyrosulfate (K2S2O7) and hydrogen peroxide (H2O2) as leaching agents. The leaching rates of lithium and iron were 99.83 % and 0.34 %, respectively, at the optimal leaching conditions of 4 vol% 30 wt% H2O2, 0.08 mol/L K2S2O7, 25℃, 5 min, and a solid–liquid ratio of 20 g/L. Meanwhile, the mechanism of the leaching process was explored by thermodynamic, XRD, XPS, FTIR, and SEM analyses. The leaching solution was concentrated and purified, with the addition of potassium carbonate (K2CO3) to convert lithium into lithium carbonate (Li2CO3). A small amount of sulfuric acid (H2SO4) is added to the saline wastewater after precipitation, which can be converted into a leaching agent for recycling after heat treatment. This study provides a sustainable green process for the recovery of lithium iron phosphate and a new idea for resource recovery.

Acetate Shock Loads Enhance CO Uptake Rates of Anaerobic Microbiomes.

Pyrolysis of lignocellulosic biomass commonly produces syngas, a mixture of gases such as CO, CO2 and H2, as well as an aqueous solution generally rich in organic acids such as acetate. In this study, we evaluated the impact of increasing acetate shock loads during syngas co-fermentation with anaerobic microbiomes at different pH levels (6.7 and 5.5) and temperatures (37°C and 55°C) by assessing substrates consumption, metabolites production and microbial community composition. The anaerobic microbiomes revealed to be remarkably resilient and were capable of converting syngas even at high acetate concentrations of up to 64 g/L and pH 5.5. Modifying process parameters and acetate loads resulted in a shift of the product spectrum and microbiota composition. Specifically, a pH of 6.7 promoted methanogens such as Methanosarcina, whereas lowering the pH to 5.5 with lower acetate loads promoted the enrichment of syntrophic acetate oxidisers such as Syntrophaceticus, alongside hydrogenotrophic methanogens. Increasing acetate loads intensified the toxicity of undissociated acetic acid, thereby inhibiting methanogenic activity. Under non-methanogenic conditions, high acetate concentrations suppressed acetogenesis in favour of hydrogenogenesis and the production of various carboxylates, including valerate, with product profiles and production rates being contingent upon temperature. A possible candidate for valerate production was identified in Oscillibacter. Across all tested conditions, acetate supplementation provided additional carbon and energy to the mixed cultures and consistently increased carboxydotrophic conversion rates up to about 20-fold observed at pH 5.5, 55°C and 48 g/L acetate compared to control experiments. Species of Methanobacterium, Methanosarcina and Methanothermobacter may have been involved in CO biomethanation. Under non-methanogenic conditions, the bacterial species responsible for CO conversion remain unclear. These results offer promise for integrating process streams, such as syngas and wastewater, as substrates for mixed culture fermentation allowing for enhanced resource circularity, mitigation of environmental impacts and decreased dependence on fossil fuels.

Biooxidation of a Pyrite-Arsenopyrite Concentrate Under Stressful Conditions

Gold recovery from refractory pyrite-arsenopyrite concentrates using stirred tank reactor biooxidation is widely applied worldwide. Therefore, studies to address the characteristic problem of this technology are urgent. The goal of the present work was to research the possibility of counteracting the negative effects of unfavorable conditions (increasing pulp density and temperature) on the biooxidation of pyrite-arsenopyrite concentrate in laboratory-scale stirred tank reactors using additional carbon supply in the form of CO2. A refractory concentrate containing pyrite (48%) and arsenopyrite (13%) was used in biooxidation experiments. In the control experiment, biooxidation was performed under “normal conditions”: temperature 40 °C, pulp density (solid to liquid ratio, S:L) 1:10, residence time 5 days. It was shown that under “normal conditions”, additional carbon dioxide supply insignificantly affected the biooxidation rate and composition of the microbial population of biooxidation reactors. In addition, the effect of “stressful conditions” was studied. In this case, either temperature or pulp density were increased (up to 50 °C and S:L 1:5, respectively), which provided unfavorable conditions for biooxidation and led to the decrease in biooxidation rate. Under “stressful conditions”, additional carbon dioxide supply affected biooxidation to a greater extent and made it possible to increase both pyrite and arsenopyrite biooxidation rates. The analysis of microbial populations showed that additional carbon dioxide supply also changed their composition.

Effects of layered walnut NiS@NTA on hydrogen storage performance of MgH2

To investigate the effects of NiS concentration in NiS/C composites on catalytic performance and hydrogen storage performance of MgH2 particles, we synthesized nitrilotriacetic acid (NTA) chelating agent–derived composites with various NiS proportions via a hydrothermal process, labeled as NiS@NTAx (x = 0.065, 0.078, 0.091, 0.107, and 0.119, respectively). The composites exhibited a layered walnut morphology. After ball milling 5 wt% NiS@NTAx with MgH2, the resulting MgH2–5 wt%NiS@NTA0.078 composite (NiS: 83.5 wt% and C: 16.5 wt%) demonstrated the excellent performance, which could absorb 3.0 wt% of H2 at 353 K and released 3.5 wt% of H2 at 573 K within 60 min, and the intital dehydrogenation temperature was decreased to 508 K.. Undergoing 20 hydrogen absorption/desorption cycles, the composite maintained hydrogenation/dehydrogenation capacity retention rates of 97.4 % and 96.4 % with activation energies of 24.1 and 67.3kJ/mol, respectively. The in situ formation of MgS and Mg2Ni catalysts promoted electron transfer during Mg and MgH2 transformation. Moreover, as a prominent transition metal, Ni Ni element reacts with the hydrogen absorption and desorption of Mg to form Mg2Ni/Mg2NiH4, which is like a “hydrogen pump” and provides additional hydrogen diffusion channels due to more interfaces. MgS additionally functioned as a catalyst in the reaction system, improving overall reaction kinetics. Carbon additives reduced particle agglomeration, stabilized the particle size, and moderately improved hydrogen diffusion during hydrogen absorption/desorption cycles. The in situ adjustment of NiS concentration in NiS/C samples and its impacts on MgH2 hydrogenation/dehydrogenation offer insights for designing high-performance sulfide catalysts.

Photoelectron-Promoted Sulfate Reduction for Heavy Metal Removal without Organic Carbon Addition.

Sulfate-reducing microorganisms (SRMs) show promise for heavy metal removal from contaminated environments, but their scalability is limited by reliance on organic carbon, sludge formation, and CO2 emissions. This study investigates using photoelectrons from biogenic (Bio-ZnS) and abiogenic (Abio-ZnS) sphalerite nanoparticles to enhance the activity of Desulfovibrio desulfuricans G20 (G20) for sulfate reduction and lead removal without organic substrates. Both Abio-ZnS and Bio-ZnS NPs promote sulfate reduction and energy production in G20 cells under illumination without the addition of organic substrates, with Bio-ZnS achieving 1.6 times greater sulfate reduction and 3.1 times higher ATP production compared to Abio-ZnS. This superior performance of Bio-ZnS NPs is due to their wider band gap, higher photoconversion efficiency, lower charge-transfer resistance, and closer proximity to cells, which enable more efficient photoelectron uptake, enhanced intracellular electron transfer, and reduced energy consumption for motion and filamentation. The uptake of photoelectrons also promotes G20s resistance to high Pb2+ concentrations through enhanced PbS precipitation, biofilm formation, enzymatic detoxification, and Pb2+ efflux, thus improving long-term and cyclic lead removal by G20 under substrate-depleted conditions. This approach harnesses solar energy, reduces reliance on organic substrates, and lowers costs and CO2 emissions, offering a sustainable solution for utilizing SRMs in bioremediation.

Effects of Manganese Carbonate Addition on the Carbocatalytic Properties of Lignocellulosic Waste for Use in the Degradation of Acetaminophen.

A carbon-based material was synthesized using potato peels (BPP) and banana pseudo-stems (BPS), both of which were modified with manganese to produce BPP-Mn and BPS-Mn, respectively. These materials were assessed for their ability to activate peroxymonosulfate (PMS) in the presence of MnCO3 to degrade acetaminophen (ACE), an emerging water contaminant. The materials underwent characterization using spectroscopic, textural, and electrochemical techniques. Manganese served a dual function: enhancing adsorption properties and facilitating the breaking of peroxide bonds. Additionally, carbonate ions played a structural role in the materials, transforming into CO2 at high temperatures and thereby increasing material porosity, which improved adsorption capabilities. This presents a notable advantage for materials that have not undergone de-lignification. Among the materials tested, BPS exhibited the highest efficiency in the carbocatalytic degradation of ACE, achieving a synergy index of 1.31 within just 5 min, with 42% ACE degradation in BPS compared to BPS-Mn, which achieved 100% ACE removal through adsorption. Reactive oxygen species such as sulfate, hydroxyl, and superoxide anion radicals were identified as the primary contributors to pollutant degradation. In contrast, no degradation was observed for BPP and BPP-Mn, which is likely linked to the lower lignin content in their precursor material. This work addressed the challenge of revalorizing lignocellulosic waste by highlighting its potential as an oxidant for emerging pollutants. Furthermore, the study demonstrated the coexistence of various reactive oxygen species, confirming the capacity of carbon-based matrices to activate PMS.

An oxycarbide-derived-carbon supported nickel ferrite/copper tungstate ternary composite for enhanced electrocatalytic activity towards the oxygen evolution reaction.

This work integrates a unique porous carbon with a binary heterostructured NiFe2O4/CuWO4 composite to enhance electrocatalytic activity towards the oxygen evolution reaction. The NiFe2O4/CuWO4 binary heterostructure was prepared through the conventional co-precipitation method. The porous carbon with turbostratic order was obtained by the selective etching of SiO2 nanodomains from preceramic polymer-derived SiOC. Finally, an optimum ternary NiFe2O4/CuWO4/C composite was prepared through hydrothermal treatment. Microstructural findings reveal that NiFe2O4/CuWO4 nanocomposite particulates are distributed homogeneously within the porous carbon matrix. Electrochemical findings reveal that the optimum composite with uniform carbon distribution requires an overpotential of 360 mV to attain a current density of 10 mA cm-2 with the lowest Tafel slope of 43 mV dec-1 as opposed to 450 mV and 55 mV dec-1, respectively, for the composites without carbon. The ternary composite demonstrated a stable potential over a prolonged period of 24 hours with enhanced mass activity. The improved electrocatalytic efficiency of the material is attributed to the presence of graphitic carbon and ample porosity within the additive carbon phase, which enhances the catalyst-electrolyte interaction interface area and electronic conductivity.

Excess particulate organic matter negatively affects the ecophysiology of the widespread soft coral Xenia umbellata

Coastal coral reefs are experiencing rising concentrations of organic matter. While dissolved organic matter (DOM), rather than particulate organic matter (POM), may negatively impact hard corals, the impact on soft corals remains unclear. We examined the physiological effect of 20 mg L−1 of organic carbon (C) addition on the widespread Indo-Pacific soft coral Xenia umbellata in a series of tank experiments over 28 days. We supplied DOM as glucose, and two POM sources as phytoplankton (2–5 μm length) and zooplankton (150–200 μm length). We comparatively assessed coral morphology, pulsation, colouration, algal symbiont densities, chlorophyll a, oxygen fluxes, and mortality. Corals in the control and DOM enrichment treatments exhibited no morphological or physiological changes, whereas, excess phyto- and zooplankton caused disfigurement of the polyp tentacles and shortening of its pinnules. This coincided with a mortality of 11 and 14%, respectively, a 35% reduction in pulsation rates, and darkening of the polyps (with excess zooplankton), while other assessed response variables remained stable. This suggests that in contrast to many hard corals, the soft coral X. umbellata is vulnerable to excess POM rather than DOM, with amplified effects upon exposure to larger particles. Our results suggest that excess POM may damage the delicate feeding apparatus of X. umbellata, thereby reducing pulsation and lowering gas exchange. In turn, this can cause nutritional, and ultimately, energy deficiencies by directly affecting heterotrophic and autotrophic feeding. Our findings indicate that the global-change-resilient soft coral X. umbellata is vulnerable to local eutrophication, particularly high concentrations of POM.

Impacts of elevated CO2 and partial defoliation on mineral element composition in rice.

This study explores how elevated CO2 concentration may alter the source-sink dynamics in rice by providing additional carbon for photosynthesis, thereby affecting nutrient absorption and distribution. A free-air CO2 enrichment experiment was conducted on a japonica cultivar Wuyunjing 27 in 2017 and 2018 growing seasons. The plants were exposed to ambient and elevated CO2 level (increased by 200 μmol·mol-1) and two source-sink manipulation treatments (control with no leaf cutting and cutting off the top three leaves at heading). The elevated CO2 significantly increased the above-ground biomass and the straw non-structural carbohydrate concentration by an average of 19.3% and 12.5%, respectively. Significant changes in the concentrations of N, S, Fe, and Zn in straw were noted under elevated CO2, with average decreases by 7.1, 7.2, 11.6, and 10.1%, respectively. The exposure to elevated CO2 significantly enhanced the elements accumulation, yet it had minimal impact on their distribution across different organs. When compared to intact rice, removing the top three leaves at heading reduced the above-ground biomass by 36.8% and the straw non-structural carbohydrate content by 44.8%. Leaf-cutting generally increased the concentration of elements in stem, leaf, and grain, likely due to a concentration effect from reduced biomass and carbohydrate accumulation. Leaf-cutting reduced element accumulation and shifted element allocation in rice organs. It increased the proportion of elements in stems while reduced their presence in leaves and grains. Our study suggests that a dilution effect may cause a decrease in mineral elements concentrations under elevated CO2 because of the increase in biomass and carbohydrates.

Investigation into Recycling of Iron Oxide Scale on H13 Steel by Low‐Temperature Carbothermal Reduction Method

The current method for recovering iron oxide scale in the steel industry is not economically optimal, especially for high‐alloy scales found in alloyed steel. This study focuses on iron oxide scale containing valuable metals like chromium (Cr), molybdenum (Mo), and vanadium (V). The required carbon addition is calculated based on the iron and chromium oxides in the scale. The effects of varying carbon additions and reduction temperatures on reduction efficiency are thoroughly examined. Kinetic studies show that as temperature and carbon increase, the rate‐limiting step shifts from interfacial diffusion to interfacial reaction. Reduction experiments assess carbon utilization, metallization rate, deoxidation rate, and removal of harmful elements. Results show that high temperatures hinder sulfur (S) and phosphorus (P) removal, and excess carbon reduces carbon utilization efficiency. Optimal conditions are a carbon ratio of 0.2174 and a temperature of 1150 °C. The carbothermic reduction product requires further refinement through conventional ladle slag systems to meet the quality standards for metallic materials. Over 65% of alloying elements are recovered, though phosphorus content remains slightly higher than in finished alloy steel. The materials from this study are suitable as high‐quality intermediates for alloy steel production.

Effects of Carbon Type and Composition on the Properties of Carbon-Copper Composite as Pantograph Slide in Railway Application

Carbon-copper composites have wide application prospects as high-speed railway pantograph slides due to the self-lubricating ability of carbon and good conductivity of copper. However, carbon-copper composites produced through powder metallurgy may still encounter challenges, such as poor wettability and lower conductivity. The experimental approach in this work involved the fabrication of carbon-copper composites using the warm compaction method, with different types and proportions of carbon materials, namely local carbon from palm kernel shells (PKS) and graphite. Characterisation and testing of hardness, density, resistivity, transverse rupture strength (TRS), and microstructure of the composites have been conducted. An increase in graphite content was found to improve the electrical conductivity of the carbon-copper composite, while the addition of local carbon has enhanced its hardness. Furthermore, the addition of graphene oxide (GO) as filler has significantly improved the mechanical strength of this composite by up to 61.34%. This research has highlighted the potential of locally sourced carbon for developing advanced pantograph slide materials for railway applications. The findings provided valuable insights into the optimisation of composite compositions to achieve the desired balancebetween electrical conductivity and mechanical performance. These carboncopper composites hold the promise of more efficient and durable pantograph slides, which can contribute to the overall reliability and sustainability of railway systems.

PEDOT:PSS as a conductive polymer binder for ecologically and economically sustainable, carbon-free NMC electrodes

In this work new dispersion medium for positive electrode slurries for lithium-ion batteries, dimethyl sulfoxide (DMSO), is proposed, in combination with PEDOT:PSS conductive polymer as a binder. Dispersion of PEDOT:PSS in concentration of 2.5% w/w with anhydrous DMSO is prepared. The electrodes were prepared with NMC622 active material and prepared PEDOT:PSS/DMSO dispersion with and without addition of conductive carbon. SEM imaging with EDS mapping confirms creation of binding film of the polymer on grains of active material. Chronopotentiometry tests of the electrodes in half-cell lithium-ion setup reveal that the best electrochemical performance was achieved for 97.5% active material and 2.5% PEDOT:PSS without conductive carbon addition (ca. 170 mAh g−1 at 0.1 C, 90% retention after 51 cycles). PEDOT:PSS enabled the elimination of the conductive carbon additive from the electrode and reduction of the binder content. It resulted in enhancement of the capacity per gram of electrode paste by approximately 17% compared with standard electrode composition.
