Abstract
A battery includes a positive electrode formed with a positive electrode active material layer containing a positive electrode active material at least on one side of a positive electrode current collector, a negative electrode formed with a negative electrode active material layer containing a negative electrode active material at least on one side of a negative electrode current collector, a separator, and an electrolyte containing solid particles. The capacity area density (mAh/cm2) of the negative electrode active material layer is equal to or higher than 2.2 mAh/cm2 and equal to or lower than 10 mAh/cm2, and the capacity area density (mAh/cm2) of a gap in the negative electrode active material layer is equal to or higher than 5.9 mAh/cm2 and equal to or lower than 67 mAh/cm2.
