Lithium-rich manganese-based positive electrode material and preparation method therefor |
| abstract |
A lithium-rich manganese-based cathode material represented by the formula (I). In the X-ray diffraction pattern of the lithium-rich manganese-based cathode material, the ratio of the diffraction peak intensity at a Bragg angle of about 18.7 DEG to the diffraction peak intensity at a Bragg angle of about 44.6 DEG is from 1.10 to 1.24. The method for preparing the lithium-rich manganese-based cathode material includes: mixing a lithium-rich manganese-based compound with a lithium remover; And under the effect of a lithium agent, by removing the portion of the Li 2 O from Li 2 MnO 3 of the lithium-rich manganese-based compound, and a step of obtaining a lithium-rich manganese-based cathode material. The initial Coulomb efficiency is improved due to the reduction of the irreversible product Li 2 O; Due to the presence of lithium vacancy and oxygen vacancies, lithium-rich manganese-based cathode materials exhibit good rate performance and cycle performace.
