| titleOfInvention | A kind of titanium-doped vanadium manganese phosphate sodium sodium ion battery cathode material and preparation method thereof |
| abstract | The invention discloses a titanium-doped vanadium manganese sodium phosphate sodium ion battery positive electrode material, the chemical formula is Na 3+x MnTi 1-x V x (PO 4 ) 3 , wherein the value range of x is 0.6≤x≤1 , belonging to the rhombus NASICON type structure, the space group is R-3c; the preparation process includes adding sodium source, manganese source, titanium source, vanadium source, ammonium dihydrogen phosphate and citric acid monohydrate into distilled water to obtain a mixed solution; The mixed solution is subjected to magnetic stirring in a constant temperature water bath to form a precursor wet gel; the wet gel is pre-fired after drying, and then fired to obtain a titanium with a chemical formula of Na 3+x MnTi 1-x V x (PO 4 ) 3 Doped vanadium manganese sodium phosphate sodium ion battery positive electrode material; the present invention partially replaces vanadium by titanium in the vanadium manganese sodium phosphate positive electrode material, so that it can maintain a high specific capacity while showing excellent cycle performance and rate performance , extending the service life of the battery, while reducing the amount of toxic and expensive vanadium element, bringing good environmental and economic benefits. |
