Abstract

A method for producing a battery module having a plurality of individual electrochemical cells, includes the following steps: —arranging cell cans; —embedding the cell cans in a metal foam; and —inserting cell coils into the cell cans. The metal foam is used hereby as common negative pole or positive pole of the single cells.

First claim

What is claimed is:

1. A battery module, comprising:
a plurality of single electrochemical cells embedded in a metal foam,
each said cell including a cell can made of an electrically conductive material including steel, aluminum, copper, and alloys thereof, and said cell can directly enclosed by the metal foam,
wherein the metal foam is made of an aluminum alloy, and
a cell coil arranged in the cell can,
said metal foam establishing a common negative pole or positive pole of the single cells.

2. The battery module of claim 1 , further comprising a cover configured to close the cell cans.

3. The battery module of claim 1 , wherein the metal foam has at least one filler.

4. The battery module of claim 3 , wherein the at least one filler includes hollow glass beads.

5. The battery module of claim 4 , wherein the hollow glass beads are filled with a phase change material.
