OPzV Battery adopt gel electrolyte and PVC-SiO
2
Separator to set up oxygen cycle principle:
Battery is full of gel electrolyte inside, and A 3-D porous network is formed with framework of SiO
2.
The net contains electrolyte necessary for battery. At initial stage, the construction is not steady. As
time goes on, the framework is shrink and some cracks appeared in the gel. The cracks exist
between pos.& neg. plates and separator and become a path between the positive and the
negative. Thus it is possible to build GEL battery in sealed structure.
