PURPOSE:To improve service life of a lead battery, by making the outer side of the both end walls in the direction of laminating electrode plates into about a half circle with larger thickness at the center, and binding the side of the battery casing with heat-resisting belts. CONSTITUTION:The battery casing 1 is formed of shorter side outer walls 2 made into about a half circle with larger thickness at the center, facing the direction of the electrode plates lamination which consists of anode and cathode plates, and separators of micro-glassfiber mats, and longer side plain outer walls 4 square to the electrode plates lamination direction. To reinforce the shorter side walls 2 of the battery casing 1, it is bound with heat-resisting belts such as copper belts, to prevent expansion of the casing 1 when the temperature of the battery rises. Therefore, the mechanical strength of the battery casing 1 is increased broadly, and the adhesion between the active substance surfaces of cathode and anode plates, and the separators of micro-glassfiber mats is stabilized, resulting in an extensive improvement of the service life. |
