Damage mechanisms and recent research advances in Ni‐rich layered cathode materials for lithium‐ion batteries

Abstract Nickel‐rich cathode is considered to be the cathode material that can solve the short‐range problem of electric vehicles with excellent electrochemical properties and low price. However, microcracks, lithium–nickel hybridization, and irreversible phase transitions during cycling limit their commercial applications. These issues should be resolved by modifications. In recent years, it has been favored by researchers to solve a large number of problems by combining multiple modification strategies. Therefore, this paper reviews recent developments in various modification techniques for nickel‐rich cathode materials that have improved their electrochemical characteristics. The summary of multiple modifications of nickel‐rich materials will play a guiding role in future development.
