ALL-SOLID SECONDARY BATTERY AND POSITIVE ELECTRODE USED THEREFOR

摘要

An all-solid secondary battery having excellent output characteristics and cycle characteristics, and a positive electrode used therefor includes a positive electrode active material which includes LiMeO2. The Me includes at least one metal element. A variation rate of the lattice constant a and a variation rate of the lattice constant c between LiMeO2 before the deintercalation of Li and Li1-xMeO2 (0
