摘要： PURPOSE:To increase trickle cycle life and to reduce production cost by arranging a particle filled layer whose parctcles have mean pore sizes larger than the mean particle size of a separator in the surroundings of an electrode group. CONSTITUTION:Glass fibers having a specified mean diameter and a specified porosity is used in a separator. A positive plate and a negative plate combined with the separator are put into a container 1. Glass beads with a specified particle size are filled densely in a space surrounding an electrode group 2 from an electrolyte pouring hole 5 to form a particle filled layer 3. Foamed phenol resin with continuous pores is packed in the electrolyte pouring hole 5 to press the glass beads. Dilute sulfuric acid is poured into the container 1. The pouring electrolyte amount is limited to such a level that even if a battery is turned upside down, the electrolyte is not spilled out from the battery. The glass beads are made of soda-lime glass and have almost truly globular shapes, and have almost no pores. Particles of acrylic resin or polypropylene resin are used in addition to glass beads.

摘要： PURPOSE:To contain alkaline metal ions with the specified concentration in an electrolyte only through the injection of the normal electrolyte into a storage battery by filling alkaline metal salt or alkaline earth metal salt in voids between fibers of a separator or a mat. CONSTITUTION:A separator 6 is paper-made with fine fibers such as pulp or polyethylene, sodium sulfate 9 is arranged in voids between fibers 8. When normal dilute sulfuric acid is injected into a storage battery, the sodium sulfate 9 is easily solved, sodium ions can be uniformly contained in an electrolyte. The electrolyte containing alkaline metal ions or alkaline earth metal ions can be generated in the battery when a user just injects the normal dilute sulfuric acid.

摘要： PURPOSE:To reduce the number of assembly process and to adapt even to a large capacity of battery by opening one surfaces of two battery jars, housing therein by dividing an electrode plate group respectively, fusing and sealing the outer peripheries of the battery jars with synthetic resin sheets whose center parts are opened, and fusing and sealing the sheets each other. CONSTITUTION:An electrode plate group which consists of a negative electrode plate 4, a separator 5, and a positive electrode plate 3 is housed in the recess 2 in a battery jar 1, while an electrode plate group which consists of a negative electrode plate 4' and a separator 5' is housed in the recess in a battery jar 1'. In such a condition, synthetic resin sheets 6 and 6' which have no center parts to prevent to interfere in the electrode plate groups, having a size to protrude to the outer peripheries of the battery jars, and allowing to heat-fusing, are fused to attach to the battery jars 1 and 1'. Furthermore, the protruding parts just outside the fusing surfaces between the two sheets 6 and 6' and the battery jars 1 and 1 are fused and sealed to form one cell. By such a constitution, the housing work of the electrode plate groups is made easier, the number of assembly process is reduced, and it can be adapted even to a large capacity battery.
