锂离子电池目前已广泛应用于人们的生产生活中，并促使手机、笔记本电脑、数码相机等技术得到高速发展。此外，随着电动汽车行业的迅猛发展，锂离子电池在动力储能电源方面的应用占比也逐年增加。锂离子电池主要依靠锂离子在正极和负极之间移动来工作。在充放电过程中，锂离子在两个电极之间往返嵌入和脱嵌：充电时，锂离子从正极脱嵌，经过电解质嵌入负极，负极处于富锂状态；放电时则相反。锂离子电极材料应满足以下三个条件：一是充放电过程中，材料与电解质有较好的电化学相容性，且在全充电状态下保持电化学稳定性；二是具有较好的电极过程动力学性能；三是具有锂离子嵌入脱出的完全可逆性能。我们主要针对锂离子电池电极材料（富锂锰、无钴高镍、生物炭等）进行研究，并与广东工业大学和四川朗晟新能源科技有限公司进行合作研究。
