1. A battery comprising:
a cathode; an anode; and an electrolytic solution, wherein the anode comprises an anode active material layer provided on at least one side of an anode current collector, and the anode active material layer comprises an anode active material consisting of a carbon material or a plurality of carbon materials and has a thickness of 30 μm to 100 μm on a single side of the anode current collector, wherein the electrolytic solution contains a solvent and an electrolyte salt, wherein the solvent contains a sulfone compound selected from the group consisting of sulfone compounds shown in Chemical formula 1 and Chemical formula 2: where R1 represents CmH2m-nXn, and X represents a halogen; m represents one of integer numbers of from 2 to 4; and n represents one of integer numbers of from 0 to 2m; where R2 represents CjH2j-kXk, and X represents a halogen; j represents one of integer numbers of from 2 to 4; and k represents one of integer numbers of from 0 to 2j, and wherein the solvent contains a cyclic ester carbonate having a halogen shown in Chemical formula 6: where R11, R12, R13, and R14 represent a hydrogen group, a halogen group, an alkyl group, or an alkyl halide group; and at least one thereof is the halogen group or the alkyl halide group, wherein the thickness of the anode active material layer ranges from 30 μm to 60 μm, and wherein the battery includes a gel electrolyte that includes the electrolytic solution and a polymer compound that holds the electrolytic solution. |
