Battery

A battery comprising:

• an anode, a cathode and an electrolyte;
• wherein the electrolyte includes one or both of fluoro ethylene carbonate and difluoro ethylene carbonate in an amount of 0.5% by mass or more and 10% by mass or less,
• wherein the anode includes an anode active material layer provided on an anode current collector, and
• wherein a thickness of the anode active material layer, after charging the battery, is 58 um or more and 75 um or less;
• wherein a ratio of a discharge capacity B, when discharging at a 5 C rate, to a discharge capacity A, when discharging at a 0.2 C rate, ((B/A)×100%) is 80% or more.
