Abstract

A storage battery comprising electrode plate groups including anode plates and cathode plates, a battery casing for accommodating said electrode plate groups and electrolyte, a closure covering said battery casing, and face heaters so treated as to be of electrolyte-resistance and provided in said battery casing, wherein said electrolyte is effectively heated to prevent the electromotive force from being decreased due to a decrease in temperature of said electrolyte, thereby producing a constant electromotive force.

Claims

2. A storage battery as defined in claim 1, wherein said face heaters have a high weave density portion formed in one edge portion of said heat-resistant cloth with said heating wire woven thereinto.

3. A storage battery as defined in claim 1, wherein said heating wire is distributed more densely toward the bottom than the top of said face heaters.

4. A storage battery as defined in claim 1, wherein said lead wires connected with said face heaters are embedded in an insulating and electrolyte-resistant adhesive means, said adhesive means adhering said battery casing closure to said battery casing.

5. A storage battery as defined in claim 1, wherein said lead wires connected with said face heaters are embedded in a sealing compound for sealing said battery casing and said battery casing closure.
