    摘要： The battery of this invention includes a positive electrode including a gelled polymeric electrolyte (A) and using spinel type lithium manganese oxide as an active material; a negative electrode; a gelled polymeric electrolyte (B) in the shape of a film or sheet also serving as a separator, and both the gelled polymeric electrolyte (A) and the gelled polymeric electrolyte (B) are made from a polymer of poly(alkylene oxide) series impregnated with a liquid electrolyte. Since the battery includes the positive electrode using the specific gelled polymeric electrolyte (A), a contact area between the positive electrode active material and the gelled polymeric electrolyte is large, so as to attain large initial discharge capacity (at high rate discharge in particular). Also, since the battery includes the specific gelled polymeric electrolyte (B) as the electrolyte, manganese included in the spinel type lithium manganese oxide is minimally eluted, and hence, the discharge capacity is minimally degraded during charge-discharge cycles due to elution of manganese, resulting in attaining good charge-discharge cycle performance.

    摘要翻译： 本发明的电池包括含有胶凝聚合物电解质（A）和使用尖晶石型锂锰氧化物作为活性材料的正电极; 负极; 胶状聚合物电解质（B）为薄膜或片材形状，也用作隔膜，凝胶状高分子电解质（A）和凝胶状聚合物电解质（B）均由聚（环氧烷）系列 用液体电解质浸渍。 由于电池包括使用特定凝胶状高分子电解质（A）的正极，所以正极活性物质与凝胶状聚合物电解质之间的接触面积大，以达到大的初始放电容量（特别是高倍率放电） 。 此外，由于电池包含作为电解质的特定凝胶状聚合物电解质（B），所以尖晶石型锂锰氧化物中所含的锰被最小程度地洗脱，因此在充放电循环中由于锰的洗脱而导致的放电容量最小化 ，从而获得良好的充放电循环性能。
