    摘要: A non-aqueous electrolyte secondary battery that uses a layered lithium-transition metal composite oxide as a positive electrode active material can alleviate reduction in battery capacity associated with charge-discharge cycling at high temperatures and can enhance elevated-temperature durability, that is, high-temperature cycle performance. A non-aqueous electrolyte secondary battery includes a positive electrode containing a positive electrode active material capable of intercalating and deintercalating lithium, a negative electrode containing a negative electrode active material capable of intercalating and deintercalating lithium, and a non-aqueous electrolyte having lithium ion conductivity. The non-aqueous electrolyte secondary battery uses a layered lithium-transition metal composite oxide superficially coated with microparticles of Al2O3 as the positive electrode active material.

    摘要: A positive electrode for a secondary battery and a secondary battery. A mixture of at least a lithium metal oxide with a hexagonal crystal structure (belonging to the R3m space group) containing nickel (Ni) and a lithium manganese oxide with a rhombic crystal structure (belonging to the Pmmn space group) is used for the positive electrode active material. Furthermore, it is preferable for the lithium metal oxide described above to include manganese (Mn) and more preferable for cobalt (Co) to be included to improve the stability of the crystal structure. In addition, it is preferable for the proportion of the lithium manganese oxide in the mixture described above to be from 20% by weight to 80% by weight.
