Abstract
A battery capable of inhibiting temperature increase and an anode used for it are provided. An anode active material layer contains an anode active material and a polymer containing a binder, vinylidene fluoride, as a component. A calorific value by differential scanning calorimetry in charging the anode active material layer is 500 J/g or less in the range from 230 deg C. to 370 deg C., and is preferably 400 J/g or less. Further, a difference between the maximum value of calorific value and a calorific value at 100 deg C. is 1.70 W/g or less, and is preferably 1.60 W/g or less.
