Active substances, electrodes, nonaqueous electrolyte secondary cells, and a process for fabricating the active substances

摘要：

The present invention provides a positive electrode of a nonaqueous electrolyte secondary cell which is prepared using an active substance containing a composition of LiNiaCobMcO2 (a+b+c=1;0≦c≦0.5) wherein M is at least one metal selected from among Mn, Fe, Zn, Ti, Cr, Mg, Al, Cu, or Ga and a composition of AlX(SO4)2 wherein X is at least one material selected from among Na, Rb, Cs, or NH4. This enables the secondary cell to diminish the reduction of a cell capacity when allowed to store and thus the storage characteristics of the secondary cell is improved.

摘要（中）：

本发明提供一种非水电解质二次电池的正极，其使用含有LiNiaCobMcO2（a + b + c = 1; 0 <= c <0.5）的组成的活性物质制备，其中M为至少一种选择的金属 Mn，Fe，Zn，Ti，Cr，Mg，Al，Cu或Ga中的一种以及Al（SO 4）2的组成，其中X为选自Na，Rb，Cs或NH 4中的至少一种。这使得二次电池在允许存储时能够减小电池容量的降低，从而提高二次电池的存储特性。
