Abstract
Provided is a laminate battery in which a short circuit between a negative electrode active material and a positive electrode due to expansion of the negative electrode active material during discharging is prevented. A laminate battery includes a battery case that serves as an outer case. The laminate battery includes an inner case within a battery case, and the inner case is formed of a positive electrode storage case and a separator. An inside of the inner case serves as a positive electrode storage portion that stores a positive electrode. An outside of the inner case serves as a negative electrode storage portion that stores a negative electrode. The negative electrode uses a particulate negative electrode active material (e.g., zinc or zinc oxide).
