非水电解液二次电池
摘要：
本发明的目的在于，提供一种非水电解液二次电池，其能够同时抑制高温充电储存后的放电性能的降低和残留容量的降低。其特征在于，其具备：包含正极活性物质的正极、包含负极活性物质的负极、非水电解液、和设置于上述正极和上述负极之间的隔离体，上述正极活性物质包含钴酸锂、和附着于该钴酸锂(21)的至少一部分表面的铒化合物(22)，并且，上述非水电解液中含有1,3-双(异氰酸根合甲基)环己烷。
摘要（英）：

The purpose of the present invention is to provide a non-aqueous electrolyte secondary cell that makes it possible to inhibit any decrease in residual capacity and discharge performance subsequent to high-temperature charging and storage. The invention is characterized in being provided with a positive electrode having a positive electrode active substance, a negative electrode having a negative electrode active substance, a non-aqueous electrolyte, and a separator provided between the positive electrode and the negative electrode. The positive electrode active substance comprises lithium cobaltate (21) and an erbium compound (22) fixed on at least some of the surface of the lithium cobaltate (21), and the non-aqueous electrolyte contains 1,3-bis(isocyanatomethyl)cyclohexane.
