摘要

镍钴锰三元材料作为一种重要的锂离子电池正极材料，与钴酸锂、镍酸锂和锰酸锂相比，因其具有循环性能好、放电容量大、热稳定性好、成本低、结构比较稳定等优点受到学术界和产业界的广泛关注。目前，镍钴锰三元正极材料已经成功地应用于锂离子电池中，但也存在许多缺点，如在首次循环过程中的不可逆容量损失严重、在镍含量较高时循环性能和热稳定性变差、表面反应不均匀等，从而在一定程度上影响了锂离子电池的性能。本文主要综述了对镍钴锰三元正极材料的掺杂、包覆等改性的研究进展，并对镍钴锰三元正极材料的未来发展趋势做了展望。

Abstract

LiN

1-x-y

is an important cathode material for lithium-ion batteries (LIBs). Compared with lithium cobalt oxide

lithium nickel oxide and lithium manganate

LiNi

1-x-y

is widely concerned by the field of academia and industry due to good cycle performance

large capacity

good thermal stability

low cost

relatively stable structure and so on. At present

LiN

1-x-y

cathode materials have been successfully used in lithium-ion batteries

but there are also many disadvantages

such as severe irreversible capacity loss during the first cycle

the poor cyclic performance and thermal stability when the nickel content is high

uneven surface reaction

which affected the performance of lithium-ion battery. In this review

modification methods such as doping and coating are summarized

and the future development trend of LiN

1-x-y

materials is discussed.
