Title:
非水系電解液二次電池
Document Type and Number:
Japanese Patent JP4910239
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte solution secondary with reduced HF in the electrolyte solution which can be in a state where an HP portion is reduced even if water gets mixed from an electrode or the like at battery assembly. SOLUTION: With the nonaqueous electrolyte solution secondary battery provided with an anode which can at least absorb and discharge lithium, a cathode, a solute, and an organic solvent, ester phosphite expressed in formula (I) below is characteristically added by 0.01 to 0.9 wt.% against total electrolyte solution in the organic solvent. (In the formula, R<1> , R<2> , and R<3> represent, each independently, a methyl group or an ethyl group).
