Abstract

A lead storage battery provided with a plurality of polar plate groups in which a plurality of positive plates and negative plates are stacked together interposed by separators, and a plurality of cell chambers accommodating the polar plate group together with an electrolyte, wherein the polar plates having the same polarity in the polar plate group are connected together through a polar plate-connecting plate, the multiple cell chambers are adjacently arrayed, and the polar plate groups accommodated in adjacent cell chambers are connected together in series through a connection body connected to the polar plate-connecting plate. Among the polar plate-connecting plates connected to the polar plate groups accommodated in the cell chambers located at the edges, one polar plate-connecting plate is connected to a polar column connected with an external terminal. The polar plate-connecting plate, the connection body and the polar column comprise a lead alloy not containing Sb but containing Sn. The connection body and / or the polar column has a greater content ratio of Sn than the polar plate-connecting plate.

Description

technical field [0001] The present invention relates to lead storage batteries for idling-stop vehicles. Background technique [0002] Idling stop vehicles can increase fuel consumption by stopping the engine while stationary. However, since the lead-acid battery supplies all the electric power for the air conditioner, the fan, etc. during idling stop, the lead-acid battery is easily undercharged. For this reason, lead storage batteries are required to have a high charge acceptance that can charge a larger amount in a short time in order to eliminate insufficient charging. In addition, the idling stop vehicle needs to frequently switch the engine on and off, so the next discharge is performed before the lead sulfate generated by the discharge is restored to lead dioxide and lead through charging. For this reason, the lifespan of a lead-acid storage battery will fall easily. Therefore, in order to eliminate the reduction of life, lead acid batteries are also required to ha...
