Abstract
A battery module comprises a flat cell including a laminate film; an electric power generating element; lead terminals; a cell outer case junction part formed by partially or completely covering the electric power generating element with the laminate film, and by sealing the laminate film by thermal fusion; a cell assembly formed by collecting a plurality of the flat cells; and a pair of planar supports for interposing the cell assembly. Further, the battery module comprises rib-shaped protrusions respectively including electrical conductors for electrically connecting the lead terminals of the flat cells, the rib-shaped protrusions being held on the planar support at predetermined intervals, and the planar supports pressing and supporting the cell assembly.
Claims5
A battery module, comprising:
- a flat cell comprising:
- a laminate film constituted by a polymer-metal composite, the laminate film being a cell outer case;
- an electric power generating element formed by stacking or winding a positive electrode plate, a separator and a negative electrode plate;
- lead terminals for flowing and receiving current to/from the electric power generating element;
- a cell outer case junction part formed by partially or completely covering the electric power generating element with the laminate film, and by sealing the laminate film by thermal fusion;
- a cell assembly formed by collecting a plurality of the flat cells;
- and
- a pair of planar supports for interposing the cell assembly from a direction opposed to planes of the flat cells;
- wherein rib-shaped protrusions respectively including electrical conductors for electrically connecting the lead terminals of a plurality of the flat cells are provided on at least one of the planar supports, the rib-shaped protrusions being held on the planar support at predetermined intervals, and the planar supports pressing and supporting the cell assembly.
