Title: Method for manufacturing positive electrode active material
Inventor: TAKAHASHI MASAHIRO
IPC: H01M4/525
Filed: 2020-05-14
Abstract: To provide a positive electrode active material for a lithium-ion secondary battery, which has higher capacity and excellent charge and discharge cycle characteristics.SOLUTION: A positive electrode active material has a small difference in a crystal structure between a charged state and a discharged state. For example, the crystal structure and volume of the positive electrode active material, which has a layered rock-salt crystal structure in the discharged state and a pseudo-spinel crystal structure in a state charged at a high voltage of approximately 4.6 V, are less likely to be changed before and after charging and discharging as compared with those of a known positive electrode active material. In order to form the positive electrode active material having the pseudo-spinel crystal structure in the charged state, it is preferable that, after lithium cobalt oxide is synthesized, lithium fluoride and magnesium fluoride are added to the lithium cobalt oxide to be mixed, and then the mixture is heated at an appropriate temperature for an appropriate time.SELECTED DRAWING: Figure 1
