| titleOfInvention | Preparation method of high-property lithium manganate gradient anode material |
| abstract | The invention discloses a high-property lithium manganate gradient anode material. The high-property lithium manganate gradient anode material consists of a manganese source material, a lithium source material, a doping agent M and a coating material, wherein a mol ratio of Li to Mn is 0.45-0.65; a doping amount of the doping agent M is 0.01wt%-10wt% of lithium manganate; and a doping amount of a coating material is 0.01wt%-20wt% of the lithium manganate. With the adoption of the high-property lithium manganate gradient anode material, the structural stability of the lithium manganate is improved in a doping manner; the gradient variation of a material concentration is realized in a coating manner; the coating effect is fully realized; the structure of the material is stabilized; the circulation property and the high-temperature property can be improved; the specific discharge capacity can be up to more than 110mAh/g; and the capacity retention ratio is up to more than 94% at a high temperature of 45 DEG C after 100 cycles, the capacity retention ratio is up to more than 92% at a high temperature of 60 DEG C and the capacity retention ratio is up to more than 89% at a high temperature of 70 DEG C. |
