摘要: A non-aqueous electrolyte battery capable of making behavior of the battery calm at a time of battery abnormality to secure safety is provided. In a lithium-ion secondary battery 20, an electrode group 6 is accommodated in a cylindrical battery container 7 having a bottom. A positive electrode plate and a negative electrode plate are wound via separators W5 to form the electrode group 6. The positive electrode plate has an aluminum foil W1 as a positive electrode collector. A positive electrode mixture including a lithium transition metal complex oxide as a positive electrode active material is applied to both surfaces of the aluminum foil W1 to form a positive electrode mixture layer W2. A flame retardant layer W6 containing a flame retardant is formed at a surface of the positive electrode mixture layer W2. The negative electrode plate has a rolled copper foil W3 as a negative electrode collector. A negative electrode mixture including a carbon material as a negative electrode active material is applied to both surfaces of the rolled copper foil W3 to form a negative electrode mixture layer W4. The flame retardant decomposes under a high temperature environment such as battery abnormality or the like.

摘要: A lithium ion battery capable of maintaining for a long time fire resistance of a nonaqueous electrolytic solution at a time of battery abnormality to secure safety is provided. In the lithium ion battery, two kinds of organic solvent, EC and DEC, are used for mixed organic solvent which forms the nonaqueous electrolytic solution, and liquid flame retardant formed by phosphazene A having a boiling point closely to that of EC and phosphazene B having a boiling point closely to that of DEC is added to the electrolytic solution. At battery abnormality, when the battery temperature goes up due to internal short circuit of positive and negative electrodes caused by melting of separators to decompose each of EC and DEC, the phosphazene A and B, each having the boiling point closely to that of EC and DEC, decompose timely to function, thereby fire resistance of the electrolytic solution can be maintained for a long time to secure safety of the battery at the time of battery abnormality.

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 LiBF4 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.
