Abstract

Abstract With the increasing scarcity of non-recyclable resources such as international fossil energy and coal industries, representatives from various countries at the Paris Summit advocated the strategy of “carbon neutrality, carbon peaking” and promoted the use of recyclable resources, namely electricity. There are many ways to generate electricity, such as solar power, hydroelectric power, thermal power, tidal power and wind power. However, the method of mobile storage of electricity is relatively single - using batteries. The most widely used mobile battery currently is lithium-ion battery. This research will focus on the different choices of cathode materials for lithium-ion batteries, analysing and comparing their performance, functional stability, lifespan, capacity, price, and working conditions under extreme temperatures. At the same time, in-depth analysis will be conducted on existing electrode material recycling methods. Finally, the development direction of electrode materials with economic benefits and promising development prospects, as well as recycling methods that are more in line with economic benefits and increase resource utilization, are proposed.
