Research Status of Cathode Materials for Lithium Ion Batteries

Abstract

Thanks to the promotion of new energy vehicles, the industry of lithium-ion batteries has ushered in its booming period. The current industry of lithium ion batteries is in rapid development with great potential. Therefore, many researchers have turned to focus on lithium ion batteries to obtain better lithium ion batteries. In this paper, the literature review of cathode materials for lithium ion batteries is to be carried out from the following aspects, including the overview of lithium ion batteries, their basic performance indexes, and the classification and preparation methods of cathode materials. Besides, the present situation and modification strategies of cathode materials for lithium ion batteries will be further analyzed, so as to improve their electrochemical performance.
