Abstract

High energy density lithium-ion batteries (LIBs) are widely demanded for portable electronic devices and electrical vehicles. Layered-structure LiCoO₂ oxide (LCO) has been the most commonly used cathode material in commercial LIBs. Compared to LCO, LiNi_1-x-yMn_xCo_yO₂ (NMC) cathodes are particularly attractive due to their reduced cost and higher capacity. Among the NMC cathodes, nickel-containing LiNi_0.5Co_0.3Mn_0.2O₂ (NMC532) is one of the most promising cathode materials undergoing intensive investigation, but suffers from a series of technical issues, such as structural instability, performance fading, and safety issues. In this report, material structure and synthetic methods of LiNi_0.5Co_0.3Mn_0.2O₂, as well as current issues and progresses are introduced.
