Abstract

The utility model relates to a high-energy built-up storage battery whose housing (14) is separated into a plurality of secondary cells by a separator (6). Each secondary cell is provided with an insulating perforated plate (4) which is densely covered and penetrated by conducting nails (3). One end of the conducting nails (3) in the secondary cell on each side is connected with the extraction electrode, and the other end contacts the active substances (5) or (10), while the conducting nails in the middle secondary cells contact the active substances (5) or (10) on both ends. The storage battery consists of cascaded secondary cells in a concavo-convex manner, and an additional secondary cell will add a further unit voltage or capacity, thereby satisfying the needs on various occasions, simplifying the production process and reducing the costs. The insulating perforated plate closely contacts and penetrates conducting nails, thereby producing larger contact with active substances, improving the utilization rate of active substances, conducing to resource saving and reducing environmental pollution.
