ELECTRLYTIC SOLUTION MATERIAL, ELECTRLYTIC SOLUTION, AND SECONDARY BATTERY

摘要

A secondary battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution contains an electrolytic solution material together with a nonaqueous solvent and an electrolyte salt. The electrolytic solution material includes one or more of first unsaturated compounds and second unsaturated compounds represented, and one or more of phenol-type compounds, phosphorus-containing compounds, and sulfur-containing compounds.
