Abstract

PURPOSE:To reduce the decrease in the amount of electrolyte so as to improve the life of a sealed lead storage battery used either in a trickle charging state or in a floating charge state by coating the surface of the battery jar with metallic foil having a very small steam permeability. CONSTITUTION:When constituting a sealed lead storage battery which is used in a trickle charging or floating charge state and in which oxygen gas produced during charging is absorbed by the negative plate, a member formed by affixing films 1 made of a polyester resin or similar material to the surfaces of metallic foil 2 with a thickness of 10-200mum made of aluminum or similar material is stuck to the surface of the battery jar by means of an adhesive 3. Therefore, due to the very small steam permeability of the metallic foil 2, the decrease in electrolyte can be suppressed even when charging is performed under a condition of high ambient temperature. As a result, the increase in the internal resistance and the deterioration of the capacity of the battery are alleviated, thereby improving its life.

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sealed lead-acid battery that is used in a trickle charge state or a floating charge state and provides reliable and stable power to a load during a power outage. Example configuration and its problems This type of sealed lead-acid battery uses a sealed method in which the negative electrode plate absorbs oxygen generated during charging, so the amount of electrolyte is reduced to a state where there is no free electrolyte. Both regulation Surut,
It uses a glass fiber separator with excellent liquid absorption properties, has a safety valve at the exhaust port, and is constructed with a battery container etc. that houses the electrode group.

However, since the material of this type of battery case is polypropylene resin (hereinafter referred to as PP resin) or acrylonitrile-butylene ethylene resin (hereinafter referred to as ABS resin), the water vapor permeability is 0.1 to 3 at 25°C. .0 meeting/24-
In addition, because there is a large space between the plate group and the battery case, the surface of the battery case during trickle charging or floating charge is higher than that of conventional open lead-acid batteries, where the plate group is filled with electrolyte. A large amount of water evaporates, which is the main reason for the decrease in electrolyte solution.

As shown in Figure 1, the decrease in electrolyte is expressed by the relationship between electrolyte volume C and capacity A during trickle charging at an ambient temperature of 25°C, and between electrolyte decrease position and capacity port at 40°C. , which is accelerated as the ambient temperature of the battery increases, leading to an increase in the internal resistance of the battery, a decrease in discharge capacity, and an increase in lattice corrosion due to concentration of the electrolyte, which reduces the lifespan of sealed lead-acid batteries used in trickle charging and floating charging. This was the reason why the length was shorter than that of the conventional open lead-acid tube.
