Document Type and Number:
WIPO Patent Application WO/2019/116704
Kind Code:
A1
Abstract:
This control valve type lead acid storage battery is provided with: a positive electrode plate which comprises a collector and a positive electrode material that is supported by the collector; a negative electrode plate; and a separator which is arranged between the positive electrode plate and the negative electrode plate, and which is configured from glass fibers. The compression ratio of the separator is from 1.2 to 1.8 (inclusive). The total pore volume per unit mass of the positive electrode material is 0.150 cm3/g or less. The positive electrode material contains fibers; and the average specific surface area of the fibers as determined by a BET method that uses a krypton gas as the adsorption gas is 0.20 m2/g or more.
