A Rechargeable Zinc–Copper Voltaic Battery Built from Cost-Effective Electrodes and Electrolytes

José Fernando Flórez Gómez, Songyang Chang, Irfan Ullah, Juan C. Velez Reyes et autres

The zinc–copper (Zn-Cu) voltaic battery is the first battery made in human history, but the Cu2+ dissolution issue leads to the reaction’s irreversibility. To tackle this challenge, solid-state electrolytes, ion exchange membranes, and functional electrolytes have been proposed to mitigate the Cu2+ …
