Zinc batteries were invented in the eighteenth century, but are still in widespread use as primary commercial batteries known as aqueous alkaline batteries. In this article, we discuss the state of the art of rechargeable aqueous zinc batteries. On the one side of the battery cell, porous zinc metal electrodes offer high energy and power densities. On the other side, zinc‐air batteries perform oxygen electrocatalysis in air electrodes, while zinc‐ion batteries use intercalation electrodes. These electrodes are connected by aqueous alkaline or aqueous neutral electrolytes. We introduce the basic history, concepts, and challenges of each technology. Our overview is spiced with some details of current research.
