Abstract

Official abstract text for this publication.

Each of battery cells ( 12 ) that constitute a battery module includes a flat-shaped rolled electrode body ( 30 ) formed by rolling a sheet-like anode collector ( 32 ) and a sheet-like cathode collector ( 34 ) along with a sheet-like separator, and a trailing edge ( 32 E) of the sheet-like anode collector ( 32 ) and a trailing edge ( 34 E) of the sheet-like cathode collector ( 34 ) are located at a position ( 30 B) outside a portion of the rolled electrode body ( 30 ) 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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A battery module constructed such that a plurality of cells capable of charging and discharging are connected in series, wherein: each of the cells 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; at least two of the cells that are adjacent to each other are arranged such that flat faces of the rolled electrode bodies included in the respe…
