Abstract

PURPOSE:To increase the life of a storage battery and improve its reliability by inhibiting the phenomenon of a short circuit which may be caused due to the deposition of liberated active material by eliminating the porosity of the side areas of a separator which touch peripheral areas of a plate or decreasing the above porosity to around 50%. CONSTITUTION:Even when a separator 2 is used in a sack-like form, its parts touching the sides of a plate 1 are treated by an ultrasonic method or impregnated with an adhesive or the like so as to decrease the porosity of the parts to around 50% or eliminate the porosity thereby forming dense areas 4. Parts of the separator 2 provided with dense areas 4 are not restricted to those touching the sides of the plate 1. Such parts may be formed on the top or the bottom of the plate 1 and a great effect is achieved by providing such parts over the entire peripheral surface of the plate 1.

った。The failure modes of conventional lead-acid batteries during use or when they reach the end of their service life include falling off of the anode active material, falling off of the cathode active material, corrosion or breakage of the anode grid, and accidental failures occurring in the electrolyte. Precipitation short circuit of free active material to cathode plate? There is a phenomenon. This phenomenon may be repairable. Δ Modern storage batteries are sealed and often lead to one fatal failure. As a measure to improve this type of failure mode, the separator is made into a bag shape, and either the anode plate or the cathode plate is housed, and this has been proven to be effective as a failure mode. However, due to the current concentration of fine free active materials in the electrolytic solution, especially around the electrode plates, some of them still penetrated into the separators at the periphery of the electrode plates, so this was not perfect.

As shown in the figure, the porosity of the separator plate 2 in the core portion is reduced or eliminated by using an ultrasonic method or by impregnating the separator plate surface portion in contact with the peripheral edge of the Iε electrode plate l with an adhesive or the like. This is to form the overturned portion 4. It is to be noted that the effect will be greater if the second covered part 4 is provided on the entire peripheral surface of the electrode plate 1, such as by forming it not only on both sides of the electrode plate 1 but also on the upper or lower part.

めて大なるものである。As mentioned above, when the separator plate according to the present invention is housed, the porosity of the side edge surface that comes into contact with the peripheral edge of the electrode plate is reduced to 50% or less.
By reducing the amount of free active material to a degree I, it is possible to prevent or reduce the amount of free active material from depositing on the cathode plate via the side wall surface.
It has great industrial value, such as preventing short-circuit phenomena, preventing catastrophic failure of storage batteries, and prolonging the lifespan of storage batteries.
