CATHODE MATERIAL FOR SODIUM BATTERIES AND PREPARATION METHOD THEREOF

The present invention relates to the technical field of sodium batteries, and in particular provides a cathode material for sodium batteries and a preparation method thereof. The cathode material for sodium batteries according to the present invention is carbon layer-coated sodium iron manganese titanium silicate, where the sodium iron manganese titanium silicate has a molecular formula of NaqFexMny(TiO2)z(SiO4)m, where 1.5≤q≤52.5, 0.7≤x≤0.8, 0.2≤y≤0.3, 0.07≤z≤0.5, and 0.5≤m≤1.5. Compared with the prior art, the cathode material for sodium batteries provided by the present invention improves the capacity of resultant batteries by doping with titanium and manganese as well as carbon coating
