PURPOSE:To achieve long service life of enclosed lead storage battery through an inexpensive separator having good liquid suction performance and high tensile strength by forming the separator with compound of fibrillar synthetic fiber having water filtering factor higher than specific level, mono-filament fiber and inorganic powder. CONSTITUTION:Liquid suction separator is formed with compound of 10-30wt% of fibrillar synthetic fiber having the water filtering factor higher than 5sec/g, 10-40wt% of mono-filament fiber and 30-70wt% of inorganic powder such as diatom earth, perlite, etc. Said separator and gelatinized electrolyte are combined to produce an enclosed lead storage battery employing an inexpensive separator having good liquid suction performance and high tensile strength, resulting in a cell suitable for emergency power source in vehicle. |
