Abstract
The present disclosure relates to the field of sodium-ion batteries and discloses a sodium-chromium-titanium-manganese phosphate self-supporting electrode material, and a preparation method therefor and use thereof; the sodium-chromium-titanium-manganese phosphate self-supporting electrode material is a composite material of sodium-chromium-titanium-manganese phosphate and carbon, and the sodium-chromium-titanium-manganese phosphate has a chemical formula of NaCrTiMn(PO), wherein 0<x<1. The sodium-chromium-titanium-manganese phosphate self-supporting electrode material provided by the present disclosure has a brand-new chemical formula and crystal structure, and an electrode prepared thereby does not need a current collector, a binder, or additional conductive carbon, greatly improving the overall energy density of the electrode. When used in the sodium-ion battery, the electrode can realize multi-electron electrochemical reactions, provide excellent electrochemical performance, and especially, significantly improve the cycling stability of the material, exhibiting high voltage, high capacity, excellent rate performance, and a broad commercial application prospect.
