摘要: Ternary nickel-cobalt lithium aluminate LiNi Co Al O2 (NCA, ) is an essential cathode material with many vital advantages, such as lower cost and higher specific capacity compared cobaltate iron phosphate materials. However, the noticeably irreversible reduced cycle performance of NCA materials have restricted their further development. To solve these problems improve electrochemical performance, numerous research studies on modification been conducted, achieving promising results in recent years. In this work, progress examined from aspects surface coating bulk doping. Furthermore, future directions for are proposed.
