Zinc-Acid Battery

Zinc-air rechargeable battery cell 1.1-1.9V using ZnSO4 water electrolyte with steel sheet and carbon fiber electrodes and glass fiber separator. Battery case is HDPE plastic for high sulfuric acid and structural resistance. Single layer current capacity is approximately 100-1000mA, while 48 double sided layers give approximately 10-100A max current, leading to approximately 10-100W max power. Stacking more layers results in increased total current and power. Energy density specific energy Wh/kg depends on the weight on the steel sheet electrodes, and other battery construction materials, but is expected to be at maximum approximately 400Wh/kg. Works similarly to a lead-acid battery.
