Abstract

PURPOSE:To prevent the adverse effect on a cathode active material due to an organic additive to increase the life of a lead storage battery by making hold active carbon in a separator and making adsorb the organic additive which elutes from an anode active material to the active carbon to suppress the amount of elution into an electrolyte to the utmost. CONSTITUTION:Fine powder of active carbon 4 which is enclosed in a Japanese paper bag 3 is held between a separating body 1 and a glass mat 2 which compose a separator. The life test specified in the JIS is conducted on the lead acid battery constructed by using the separator related to this invention and the lead acid battery constructed by using the ordinary separator. Shown in the figure, the battery related to this invention shows very remarkable effect on the suppression of the capacity decrease in charge-discharge cycle. This invention can extremely increase the life of the lead storage battery by a simple means which makes hold the active carbon in the separator.

Description

【発明の詳細な説明】 本発明は、鉛蓄電池の改良に関する。[Detailed description of the invention] The present invention relates to improvements in lead-acid batteries.

て陰極活物質の凝集を防ぎ、その微細な粒子形態を維持
させている。One of the causes of capacity reduction in lead-acid batteries is the shedding of the positive electrode active material. This is due to the fact that the active material particles become finer through the charge/discharge reaction, and the bonding force between the particles weakens.By the way, the cathode active material contains a small amount of organic additive as an expansion agent. This prevents the cathode active material from agglomerating during discharge and maintains its fine particle morphology.

なる。However, as charging and discharging are repeated, the organic additive eluted into the electrolyte, and if this permeates one part of the anode active material, it will promote the miniaturization of the anode active material and hasten its falling off. .

悪影響を防ぎ、鉛蓄電池の寿命を改善するものである。In order to achieve the above object, the present invention allows the separator to hold activated carbon so that the organic additives eluted from the cathode active material are adsorbed onto the activated carbon, thereby minimizing the amount eluted into the electrolyte. This prevents the negative effects of organic additives on the anode active material and improves the lifespan of lead-acid batteries.
