Abstract Metallic zinc is an attractive anode material for aqueous rechargeable batteries because of its high theoretical capacity and low cost. However, state-of-the-art anodes suffer from coulombic efficiency severe dendrite growth during stripping/plating processes, hampering their practical applications. Here we show that eutectic-composition alloying aluminum as effective strategy substantially tackles these irreversibility issues by making use lamellar structure, composed alternating...

Alloying techniques show genuine potential to develop more effective catalysts than Pt for oxygen reduction reaction (ORR), which is the key challenge in many important electrochemical energy conversion and storage devices, such as fuel cells metal‐air batteries. Tremendous efforts have been made improve ORR activity by designing bimetallic nanocatalysts, limited only alloys of platinum transition metals (TMs). The Pt‐TM suffer from critical durability acid‐media cells. Here a new class...
Pseudocapacitance holds great promise for improving energy densities of electrochemical supercapacitors, but state-of-the-art pseudocapacitive materials show capacitances far below their theoretical values and deliver much lower levels electrical power than carbon-based due to poor cation accessibility and/or long-range electron transferability. Here we that in situ corundum-to-rutile phase transformation electron-correlated vanadium sesquioxide can yield nonstoichiometric rutile dioxide...
