In order to improve the premature capacity loss problem of 6-DZM-20 batteries for E-bikes., the 6-DZM-20 H battery was developed. In this paper, two kinds of batteries were compared and verified in terms of some design details of battery container, grid structure, assembling pressure and electrolyte. The results showed that the problems of positive active material softening, positive grid corrosion, container expansion and separator short circuit were solved basically, and the cycle life was extended significantly.
