Abstract
Each of battery cells () that constitute a battery module includes a flat-shaped rolled electrode body () formed by rolling a sheet-like anode collector () and a sheet-like cathode collector () along with a sheet-like separator, and a trailing edge (E) of the sheet-like anode collector () and a trailing edge (E) of the sheet-like cathode collector () are located at a position (B) outside a portion of the rolled electrode body () which substantially receives a restraining load. The battery module, in which the restraining load is applied to the cells, achieves long service life while maintaining good output characteristics.
