NONAQUEOUS ELECTROLYTE CELL |
摘要 |
A manganese non-aqueous electrolyte battery having safety at a time of battery abnormality and having a long life span is provided. A battery 20 has a cylindrical container 7 having a bottom. An electrode group 6 where a positive electrode plate that a spinel-related lithium manganese complex oxide is used as a positive electrode active material and a negative electrode plate that a carbon material is used as a negative electrode active material are wound via separators W5, is accommodated in the container 7. The electrode group 6 is infiltrated by an electrolytic solution in which LiBF 4 is added as an electrolyte to organic solvent. Further, a phosphazene flame retardant is added at 10 wt% to the electrolytic solution. The electrolytic solution hardly catches fire at a time of battery abnormality and manganese elution can be prevented. |
