摘要： PURPOSE:To improve liquid maintainability and liquid absorptivity, by using glass fibers in the main, containing thermoplastic organic fibers, and attaching fibers to themselves with water-glass adhesives. CONSTITUTION:Glass fibets are used in the main, thermoplastic organic fibers are also contained, and the fibers are attached to themselves with water-glass adhesives. Separators in a storage battery, whose main constituents are glass fibers, are preferrably composed of main smalldiameter glass fibers of 2mum or less in average diameter, 0-35 wt % large-diameter glass fibers of 10-30mum in average diameter, and 0-30 wt % middle-diameter glass fibers above 2 mum and below 10 mum in average diameter. The suitable content of the small- diameter glass fibers is 60 wt % or more out of the whole glass fibers, especially 65wt % or more being preferrable. water glass, and besides inorganic adhesives containing water glass are appropriate for the water-glass adhesives. Because the glass fibers hence being in the main, liquid absorptivity and liquid maintainability can be improved, particularly the liquid maintainability becoming excellent under a pressurized atmosphere.

CONSTITUTION:A separator consists of glass fiber, water absorbing fiber, and thermoplastic organic fiber. As the glass fiber, alkali-containing glass fiber having good acid resistance is preferable. As the water absorbing fiber, acrylic fiber in which water absorption treatment is applied on the surface is preferable. As the thermoplastic organic fiber, polyester is suitable from the standpoint of acid resistance and oxidization resistance. Preferable mixing ratio is 30-79wt% glass fiber, 1-20wt% water absorbing fiber, and 20-60wt% thermoplastic organic fiber. The contents of water absorbing fiber and thermoplastic organic fiber are preferable to control to 70wt% or less based on the total fiber weight.

摘要： PURPOSE:To increase the level of a liquid electrolyte held in the separator by filling the spaces between glass fibers with minute particles to minimize the diameter of the holes in the separator and using a water glass to bound the fibers together. CONSTITUTION:After fibers principally consisting of alkali-containing silicate glass fibers and a powder principally composed of an alkali-containing silicate glass powder are dispersed in water of a given pH level for a given time while avoiding the breakage of the fibers as far as possible, the thus prepared dispersion is formed into a sheet by a wet method. After that, the sheet is heated to a given temperature to bound the glass fibers and the glass powder together by the water glass existing on their surface, thereby making a separator. Since the minute particles of the powder encroach upon the spaces between the fibers during the above process, only holes with reduced diameter distribute in the entire separator. Consequently, it is possible to increase the level of a liquid electrolyte held in the separator.

摘要： PURPOSE:To prevent layering, set an apparent density/tension pressure value so as to facilitate assembling a separator in a case by composing it of specified alkali-included glass fibers only substantially, and specifying a down flow speed of electrolyte and an included quantity of sulfur in the surface of the glass fibers respectively. CONSTITUTION:A separator is substantially composed of alkali-included glass fibers of an average fiber diameter of less than 2mum only, and a down flow speed of electrolyte is set at less than 80mm/hr, while sulfur in the surface of the glass fibers is set at less than 0.02%. Though the down flow speed of the electrolyte is preferably as small as possible, injection requires much time if it is excessively small, so it is preferably 5-80mm/hr, or more preferably 20-70mm/hr. The glass fibers is preferably of alkali-included silicate glass, and that having a good acid resistance is preferably be used. Layering phenomenon is thus prevented, and the separator is easier to be assembled in a battery case.

摘要： PURPOSE:To prevent the stratification of an electrolyte and ensure the long lifetime of a battery by using a separator to keep the falling speed of the electro lyte at a rate equal to or less than the predetermined time. CONSTITUTION:A separator for keeping the falling speed of an electrolyte at a rate equal to or less than 100 mm/hour is used in a battery. The aforesaid falling speed is taken at 5 to 100mm/hour, or more preferably 20 to 70mm/hour. Also, the separator is constituted with 100% of glass fiber having an average fabric diameter of 0.65mum or less. Furthermore, the separator is substantially constituted with 95 to 30wt.% of alkaline glass fiber having an average fiber diameter of 2mum or less, and 5 to 70wt.% of silica powder manufactured via a dehumidification method and having a specific surface area of 100m /g or more.

摘要： PURPOSE:To increase electrolyte retention capacity and electrolyte absorbing capacity in addition to high strength and hardness by melt-bonding glass fibers of a separator for storage battery made of glass fiber alone. CONSTITUTION:Glass fibers mainly consist of fine glass fibers having a mean diameter of 2mum or less, and contain 0-35wt% thick glass fibers having a mean diameter of 10-30mum and 0-30wt% medium-fine glass fibers having a mean dismeter exceeding 2mum but less than l0mum. A preferable mean length of the fine glass fibers is 7-50mm and particularly 10-40mm. Alkali-containing silicate glass fiber is preferable. Relatively long fine glass fibers and midium-fine glass fibers are mixed to thick glass fibers having a given length in a proper ratio, and the mixture is dispersed with a pulper, then a glass fiber sheet is formed by a wet-type paper making process. The glass fiber sheet is dried and heated to melt a part of glass fiber. Thereby, glass fiber itself is melt- bonded each other. This heattreatment is performed at 650+ or -50 deg.C for 1-5 minutes, preferably at about 650 deg.C for 2 minutes.
