PURPOSE:To improve cycle characteristics by using lithium equivalent to a latent capacity which Li1+xMnyB2-yO4 as main material of a positive electrode has effectively for preliminary charge to achieve a large battery capacity, and setting manganese in the positive electrode main material to be composite with boon to be stabilized to be almost prevented from elusion. CONSTITUTION:A nonaqueous electrolytic secondary battery is provided with a positive electrode mainly comprising composite oxide expressed by a composition formula of Li1+xMnyB2-yO4 (where (x) is a positive number changed by a quantity of lithium required for preliminary charge of a negative electrode, and 1.6<=y<=1.9) which is capable of storage and discharge of lithium, and a negative electrode mainly comprising material capable of storage and discharge of lithium. It is also provided with a separator interposed between the positive and negative electrodes. |
