Abstract
and the capacity retention rate increases from 51.2% to 90.6% (at 1C). The microscopic characterization results show that the unique structure can significantly suppress side reactions at the cathode/electrolyte interface as well as the deterioration of structure and microcracks. This innovative design strategy combining elemental doping and construction of dual coating layers can be extended to other high nickel layered cathode materials and help improve their electrochemical performance.
