Embodiment 1
[0031] A method for preparing a titanium-doped lithium iron phosphate cathode material, characterized in that it comprises the following steps:
[0032] (1) Get raw materials: get lithium carbonate 24.8g, ferric oxide 44.39g, ammonium dihydrogen phosphate 73.93g, metal titanium powder 2.4g;
[0033] (2) heating and melting: the raw materials are mixed evenly, put into a crucible, put into a melting furnace, and heat and melt to a glass state at a certain temperature;
[0034] (3) Water quenching: adding the mixture melted to a glass state into purified water with a water temperature of 30° C., performing water quenching, and filtering the obtained semi-finished lithium iron phosphate positive electrode material;
[0035] (4) Grinding and dispersing: take 0.10 times the glucose of the semi-finished lithium iron phosphate positive electrode material on a dry basis, add it to the semi-finished lithium iron phosphate positive electrode material, and the quality of the added purifi...
