The invention relates to a multi-cell battery of electro-chemical cells of the type which is likely to be severely damaged and which is apt to release a substantial quantity of heat when short-circuited. According to the invention, the multi-cell unit is provided with a certain filler in the space between the constituent electrochemical cells, which is either a solid with a melting point in a predetermined range of temperature, or a liquid. The filler ought to be electrically non-conducting, and its quantity ought to have an adequate heat capacity and it ought also to be capable to transfer heat to adjacent cells.

Multi-cell battery

The invention relates to an electrochemical cell which is safe even under adverse conditions and abuse. The cells comprise an alkaline metal anode, a current collector and an inorganic oxyhalide liquid cathode which contains an alkaline earth metal salt in a suitable solvent, such as thionyl chloride. The cell may contain sulfur dioxide dissolved in the solvent. Suitable salts are alkaline earth metal aluminum chlorides.
