Abstract
Provided is a nonaqueous electrolytic solution containing a nonaqueous organic solvent, a solute, a specific silicon compound (A), a specific borate (B), and a specific imide salt (C), in which WB/WA, which is a ratio of a content WB of the borate (B) based on mass to a content WA of the silicon compound (A) based on mass, is 1.5 or more and 3 or less, and WC/WA, which is a ratio of a content WC of the imide salt (C) based on mass to a content WA of the silicon compound (A) based on mass, is 1 or more and 5 or less, and the nonaqueous electrolytic solution can exhibit an effect of reducing an absolute value of internal resistance at a low temperature and an effect of improving a battery capacity after a cycle test in a well-balanced manner.
