Electrochemical In Situ Na Doping to Construct High-Performance Lithium-Rich Cathode

Lithium-rich layered oxides are regarded as the next generation of cathode materials for lithium ion batteries. However, the irreversible release of oxygen during cycling can lead to serious failure problems. In order to solve the above problems, this paper proposes an electrochemical in situ Na doping method with ultrahigh content, homogenization, and no residual alkali. The traditional solid-phase sintering method has low doping content (
