Abstract: Disclosed is a cathode active material for a lithium ion secondary battery which includes a lithium manganese borate compound and a manganese oxide. The lithium manganese borate compound contains a larger amount of lithium than conventional lithium manganese borate compounds. Therefore, a larger amount of lithium is deintercalated in a battery including the cathode active material, and as a result, the specific capacity of the battery reaches 100-160 mAh/g, which is much higher than that of conventional lithium ion secondary batteries (

Abstract translation: 公开了一种锂离子二次电池用正极活性物质，其包含硼酸锰锂化合物和锰氧化物。 硼酸锰锂化合物含有比常规的硼酸锂化合物更多的锂。 因此，在含有正极活性物质的电池中，脱锂的量越多，电池的比容量达到100〜160mAh / g，比常规的锂离子二次电池高 <80mAh / g）。 还公开了一种用于制造正极活性物质的方法。
