A lithium secondary battery including: a positive electrode which contains a positive electrode active material capable of absorbing and desorbing lithium; a negative electrode which contains a negative electrode active material capable of absorbing and desorbing lithium; and a non-aqueous electrolytic solution, wherein at least one of the positive electrode or the negative electrode contains a polymer that is a reaction product of a compound (A) and a compound (B), and the non-aqueous electrolytic solution contains an additive (X). The additive (X) is at least one compound selected from the group consisting of: a carbonate compound having a carbon-carbon unsaturated bond, a carbonate compound having a halogen atom, an alkali metal salt, a sulfonic acid ester compound, a sulfuric acid ester compound, a nitrile compound, a dioxane compound, and a substituted aromatic hydrocarbon compound. The compound (A) is at least one compound selected from the group consisting of an amine compound, an amide compound, an imide compound, a maleimide compound and an imine compound. The compound (B) is a compound having two or more carbonyl groups in one molecule and being different from the compound (A). |
