The usage of this term is confirmed to the greater user community and, over time, has encouraged a myriad of remedies for solving sulfation problem.

With slow pulse fast charge not only came true high efficient fast charge, but also held down gas evolution, cleared off sulfation and fulfilled the balanced charge, so it extended the cycle life of lead acid battery.

It was found that sulfation of the negative plate was caused mainly by the lose of the organic expander and the sulfation could be eliminated through the negative material formula and charge method adjustment.

Effect of pulse charge on sulphation of lead-acid battery;

Tear-down analysis indicates that for VRLA battery,water loss,negative plate sulphation and positive active material softening are the main causes of failure.

The relationship between the water loss and lots of break downs such as sulphation, positive grid corrossion, positive active mass softening and short circuit, has been discussed.

Through researches on tussah swelling theory and practice,an irreversable swelling agent is sought out,promoting the exploration of bulky heavy_weight tussah fabrics with better finishing results such as hand touch.
