Research Status and Future Development of Cathode Materials for Lithium Ion Batteries

本文首先介绍锂离子电池充放电的工作原理,并简要介绍近年来锂离子电池碳负极材料、金属氧化物负极材料以及合金负极材料的研究状况,并以华为公司最新研究的石墨烯助力高温锂离子电池为例,指明锂离子电池的未来发展方向,锂离子电池在未来发展应朝着能量密度高、安全性能好、循环寿命长、绿色环保以及价格低廉的方向发展。

In this paper, the working principle of charge and discharge of lithium ion battery is introduced frstly, and the research status of carbon cathode material of lithium ion battery, metal oxide cathode material and alloy cathode material in recent years is briefy introduced. Taking graphene assisted high temperature lithium ion battery newly developed by Huawei as an example, the paper pointed out the future development direction of lithium ion battery. The development direction of lithium ion battery in the future should be high energy density, good safety performance, long cycle life, green environment protection and low price.
