BATTERY MODULE, METHOD OF FABRICATING THE SAME, AND VEHICLE HAVING BATTERY MODULE

摘要

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 of the sheet-like anode collector and a trailing edge of the sheet-like cathode collector are located at a position 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.
