Abstract: A battery includes a positive electrode including a positive electrode active material, a negative electrode, and an electrolytic solution including a lithium hexafluorophosphate and an additive. The positive electrode active material includes a compound having a crystal structure belonging to a space group FM3-M and represented by Compositional Formula (1): LixMeyOαFβ. The additive is at least one selected from the group consisting of difluorophosphates, tetrafluoroborates, bis(oxalate)borate salts, bis(trifluoromethanesulfonyl)imide salts, and bis(fluorosulfonyl)imide salts.
