NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
Disclosed is a non-aqueous electrolyte secondary battery which has a cathode having a cathode active material layer comprising Li(LixMn2xCo1-3x)O2 [wherein x satisfies the following requirement: 0<x<1/3] and an anode having an anode active material layer comprising Si or Sn. In the battery, it is preferred that the amounts of the cathode and anode active materials are adjusted so that a theoretical value of the capacity of the anode is 1.1 to 3.0 times greater than the capacity of the cathode at a cut-off voltage of a battery charge conducted after a preliminary battery charge, and that lithium in an amount corresponding to 9 to 50% of the theoretical value of the capacity of the anode is accumulated in the anode. |
