Recent advance in structure regulation of high-capacity Ni-rich layered oxide cathodes

High-capacity layered oxide Ni-rich cathodes are attractive to enhance the driving-range of electric vehicles because of its preferential costs. Nevertheless, in Ni-rich cathodes, there are still many issues such as microcracks generation along grain boundaries and interface side reaction between active substance and electrolyte, resulting in the rapidly deterioration of electrochemical property. Herein, improving the performance of Ni-based cathodes by structural regulation is summarized. The remaining challenges and outlook are discussed as well.
