A rechargeable storage battery includes a container, a gas venting and circuit-breaker device and a concentric electrode assembly comprised of plural negative electrode plates, positive electrode plates and separators each disposed between every two adjacent, opposite plates, wherein the gas venting and circuit-breaker device may absorb the entrained electrolyte and may disconnect a positive terminal of the cell as biased by the excessive gas pressure during overcharged operation for safety purpose; and the concentric electrode plates may overcome the breaking or deformation drawbacks since the plates are concentrically wrapped up in one-fold, instead of a conventional spiral-winding electrode configuration which is continuously rolled up by many turns.
