| abstract |
This invention relates to a non-aqueous electrolyte having high non-combustibility and a non-aqueous electrolyte secondary power source having high safety and exhibiting stable performance even under high load conditions or low-temperature conditions, and more particularly to a non-aqueous electrolyte characterized by comprising a cyclic phosphazene compound represented by the following general formula (I): n (NPR 2 ) n (I) n [wherein Rs are independently fluorine, an alkoxy group or an aryloxy group and n is 3-4], a non-aqueous solvent, LiPF 6 and at least one lithium amide selected from the group consisting of Li(FSO 2 ) 2 N, Li(CF 3 SO 2 ) 2 N and Li(C 2 F 5 SO 2 ) 2 N, as well as a non-aqueous electrolyte secondary power source comprising the non-aqueous electrolyte, a positive electrode and a negative electrode. |
