AUTO-THERMAL EVAPORATIVE LIQUID-PHASE SYNTHESIS METHOD FOR CATHODE MATERIAL FOR BATTERY

摘要

Provided is an auto-thermal evaporative liquid-phase synthesis method for cathode material for battery, comprising the following steps: (1) Adding a synthetic raw material of cathode material into a solvent to obtain a mixture A, the synthetic raw material of the cathode material containing lithium source, adding an accelerant into the mixture A, which makes the mixture A achieve a strong auto-thermal reaction to release heat to evaporate the solvent, and obtaining a solid precursor of the cathode material; (2) Drying the precursor, sintering in an atmosphere furnace and obtaining the cathode material. The method is simple in process, low in energy consumption, requirements for equipment and cost, and is applicable to industrial mass production and application. The cathode material obtained through the method is stability in batch, easy to process, low in internal resistance and high in capacity and has an excellent charging and discharging performance.
