Lithium-ion batteries (LIBs) play a key role in the global electrification of automobiles, and their long cycle life and high energy density make them the most widely used battery technology today. In LIBs, lithium-nickel-manganese oxide (LNMO) cathodes are becoming a hot research topic because this material, as an alternative to LiCoO2, not only has higher energy density and lower cost, but also exhibits better safety performance. Compared to traditional LiCoO2, LNMO can provide higher energy density, which means it can store more power in the same volume or weight, thus meeting the demand for long range in application scenarios such as electric vehicles. At the same time, LNMO is also relatively low in cost, which helps to reduce the overall manufacturing cost of lithium-ion batteries and promote their application in a wider range of fields. This paper first introduces the working principle of LIBs. Then, the crystal structure and electrochemical properties of LNMO are presented. Finally, the modification of LNMO by elemental doping and surface coating is emphasized to improve the performance of LIBs, aiming to serve as a reference for future research on LIBs.
