Research progress in O3-type layered metal oxides for sodium-ion battery
Because of high theoretical capacity and simple preparation,O3-type layered metal oxides are considered as one of the promising cathode materials for sodium-ion battery.The inherent shortcomings of layered metal oxide cathode seriously limit its commercialization process and need to be solved urgently.Problems such as irreversible phase transformation,surface erosion,and gas production are systematically summarized.The advantages and disadvantages of three common synthesis methods including solid phase method,co-precipitation method and sol-gel method are analyzed and compared,and relevant modification strategies of O3-type layered metal oxides are summarized,including element doping,surface coating,multiphase design and high entropy design.
