Single cell design
Due to the pressure inside of the battery cell, which is needed to reach a high recombination
level, a sturdy cell design is necessary to prevent leakage. The cells of the Lomain battery
are injection-molded from a single piece of plastic to prevent leakage of the cell casing and
the seams (welded or glued) of the cell cases and the lids are above the electrolyte level. The
single cell design completely eliminates the risk of faulty welded seams on the sides and on
the bottom of the cell cases. This design enhances system economy as it enables the service
personnel to replace only the defective cell(s).
