NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
Provided is a non-aqueous electrolyte secondary battery excellent in durability, the non-aqueous electrolyte secondary battery including a positive electrode active material, the surface of which is coated with a film formed of an inorganic solid electrolyte, wherein a change in volume of the positive electrode active material during charge and discharge is reduced to prevent deterioration of the film with which the surface of the positive electrode active material is coated. In a non-aqueous electrolyte secondary battery including a positive electrode active material, the surface of which is coated with a film formed of an inorganic solid electrolyte, the positive electrode active material is a lithium-containing composite oxide having a spinel structure, and contains at least one of Ti and Mg as an additional element. |
