| titleOfInvention | Preparation of a concentration-gradient magnesium-doped lithium-rich manganese-based oxide cathode material and its application in lithium batteries |
| abstract | The preparation of a concentration gradient magnesium-doped lithium-rich manganese-based oxide and its application in a lithium battery, the oxide chemical formula is Li 1.2-2x Mn 0.54 Ni 0.13 Co 0.13 Mg x O 2 , 0<x≤0.07. The specific preparation includes: (1) firstly prepare a mixed solution of manganese salt, cobalt salt and nickel salt transition metal salt according to the proportion, ammonia water and sodium carbonate mixed solution are used as complexing agent and precipitating agent, and the magnesium salt solution is injected into the transition metal salt using a peristaltic pump Mix the solution, and then add the transition metal salt solution, the precipitant and the complexing agent into the reactor by co-current to carry out co-precipitation reaction to obtain the precursor powder with element gradient distribution; (2) The precursor powder is mixed with lithium salt and calcined, and then A concentration-gradient magnesium-doped lithium-rich manganese-based cathode material is obtained. The gradient doping material is applied in the field of lithium battery, and the discharge capacity is high and the cycle performance is good. The preparation method of the invention has the advantages of low cost, good process compatibility with existing equipment, potential of quantitative production, high industrialization value and broad application prospect. |
