gas-liquid flow

An analysis has been carried out of the capabilities of the known principles of gas utilization in hermetically sealed storage batteries (nickel-cadmium and lead-acidic ones) in comparison with the method based on gas absorbtion by the working (positive and negative) electrodes with forced gas feed. Special attention is paid to the control over gas-liquid flows in hermetically sealed vessels via the match between the porous structures of the separator matrices and the active masses of the working electrodes.

The influence of porous structure of the absorptive glass mats manufactured by «Hollingsworth&Vose» (thickness 2.8 mm) and BernardDumas» (thickness 3.0 mm), modified by impregnation with polymeric emulsions on the basis of polyvinylidene fluoride (KYNAR), polyvinylpyrrolidone copolymer with styrene (PVS) and polytetrafluoroethylene (Tf), on the efficiency of ionization of hydrogen in lead-acid battery mock-ups.
