Ptve-Impregnated 3-Dimensional Porous Carbon for High-Properties Organic Battery

Abstract

Lithium-ion batteries are the most common type because their operating potential and energy density are both higher than those of other rechargeable batteries. However, the associated electrochemical reaction involves the intercalation and deintercalation of the lithium transition-metal-containing electrodes. The constituent transition-metals of lithium-ion batteries, such as cobalt, nickel, manganese, and lithium are limited resources, the cost of which is increasing as the market expands. Therefore, organic electrode materials are gaining an increased level of attention as possible replacements for lithium transition-metal-based electrode materials. The use of organic materials would enable the design of metal-free batteries. In addition to the potential low-cost and ease of scalability, the structural diversity of organic molecules would allow the tailoring of both the physical and electrochemical properties of the electrode materials, thus offering excellent opportunities for constructing sustainable and environmentally friendly power sources and energy-storage systems. However, they present some serious issues, a high self-discharge as a result of the dissolution of organic active materials into the organic liquid electrolyte and the content of large amounts of carbon conductor material into the electrode due to the intrinsic low electrical conductivity of the organic active materials.In this study, to overcome these disadvantages, 3-Dimensional porous carbon have been applied to composite with poly(2,2,6,6-tetramethylpiperidine-N-oxyl-4-vinyl ether) (PTVE) organic electrode material. The use of the PTVE-impregnated porous carbon electrode structure enhanced the contents of active material and electrochemical performance.
