Abstract
An electrolytic solution for lithium ion secondary batteries contains: a lithium salt electrolyte; an organic solvent; and an aliphatic compound having three or more carboxylic acid groups in a molecule. A lithium ion secondary battery includes: a cathode including a cathode active material that is capable of absorbing and releasing lithium and contains manganese (Mn) as a major transit metal species; an anode; and a non-aqueous electrolytic solution. The electrolytic solution is the above-described solution. The aliphatic compound has a molecular weight within the range from 50,000 to 500,000.
