NON-AQUEOUS ELECTROLYTE BATTERY |
摘要 |
A non-aqueous electrolyte battery capable of securing safety at a time of battery abnormality and restricting a drop in capacity or output at a time of battery use is provided. In a lithium-ion secondary battery 20, an electrode group 6 that positive and negative electrode plates are wound via a separator is accommodated into a battery container 7 into which a non-aqueous electrolyte is injected. In the positive electrode plate, a positive electrode mixture layer W2 including a lithium transition metal complex oxide is formed at both surfaces of an aluminum foil W1. A flame retardant layer W6 containing a phosphazene compound of a flame retardant and a polyethylene oxide of a binder having ionic conductivity is formed at a surface of the positive electrode mixture layer W2. In the negative electrode plate, a negative electrode mixture layer W6 including a carbon material of a negative electrode active material is formed at both surfaces of rolled copper foil W3. Ionic conductivity is secured by the polyethylene oxide and the phosphazene compound decomposes when a battery temperature goes up due to battery abnormality. |
