Lamellar Nanoporous Metal/Intermetallic Compound Heterostructure Regulating Dendrite‐Free Zinc Electrodeposition for Wide‐Temperature Aqueous Zinc‐Ion Battery

Aqueous zinc-ion batteries are attractive post-lithium battery technologies for grid-scale energy storage because of their inherent safety, low cost and high theoretical capacity. However, their practical implementation in wide-temperature surroundings persistently confronts irregular zinc electrodeposits and parasitic side reactions on metal anode, which leads to poor rechargeability, low Coulombic efficiency and short lifespan. Here, this work reports lamellar nanoporous Cu/Al
