Abstract
With the rapid growth of lithium-ion batteries (LIBs) industry and market, it is important to develop LIBs with higher capacities, stability and lifespan. However, challenges like low conductivity, solid electrolyte interface formation and electrode cracking now are in the way, which are closely related to electrode deficiency. Hence, to obtain better performance, the main orientation is to improve electrode materials’ morphological structure. Better porosity, stability and conductivity of anode and cathode materials tangibly improve the performance of LIBs including coulombic efficiency, safety and cyclic lifespan. This review paper will combine current challenges, commonly used and emerging electrode materials together with battery testing methods and their market trend to provide a big picture about LIBs
Highlights
Due to the rapid consumption of fossil fuels for modern industry and transportation together with the rapid evolution in electrical storage, it is in a pressing need to find other energy sources to replace the vacancy of fossil fuel to keep the operation of industry and catch up the market trend
Thermal runaway is a major concern for lithium-ion batteries (LIBs) application [2], and this problem is commonly occurred in the lithium transition metal oxide, for example, lithium cobalt oxide has the lowest thermal stability of any commercial cathode material [37]
The aforementioned article has already presented a framework for LIBs current challenges, electrode materials, testing method and their market trend
Summary
Due to the rapid consumption of fossil fuels for modern industry and transportation together with the rapid evolution in electrical storage, it is in a pressing need to find other energy sources to replace the vacancy of fossil fuel to keep the operation of industry and catch up the market trend. This lithium-ion battery (LIB) is composed of copper, aluminium as anode and cathode electrodes. It takes graphite as anode material and lithium nickel cobalt aluminium oxide as cathode with a separator and electrolyte between them. This structure is a standard form of LIBs and its Swiss-roll like structure maximize its amount of active material for more energy[1]. Capacity and large-scale equipment like electrical vehicle (EV) and grid storage requires for high power and capacity. These nanomaterials can be customized into specified structure for different usage and have wide applications in electrode development
