Research Progress on Layered Metal Oxide Cathode Materials for Sodium-lon Batteries
With low cost,high safety performance,good low-temperature performance and long cycle life,so-dium ion batteries are the next generation secondary batteries that are expected to replace lithium-ion batteries for the large-scale energy storage.In recent decades,various cathode materials for sodium-ion batteries have been ex-tensively studied,among which the P2 and O3 type layered metal oxides are the most promising cathode materials.In this review,developments in the last five years for improving the capacity,stability,and multiplicity performance of this class of materials are reviewed mainly in terms of chemical compositions,doping modifications,and structural optimizations.Moreover,an outlook on the applications of layered cathode materials in sodium-ion batteries is given.
