The other
two types of polymeric emulsions under test (polyvinylpyrollidonestyrene
–MPVS and polyvinylpyrrolidone “Luviskol” –MPVP) also
improve the reversibility of the charge and discharge processes at
the two electrodes, but with less contribution to the cycle life performance
of VRLA batteries. The results of this study prove that
the proposed three-layeredmembrane AGMseparator can be used
as an efficient component in VRLA battery design improving the
performance characteristics of valve-regulated lead-acid batteries.
