Abstract Metallic zinc (Zn) is considered as one of the most attractive anode materials for post‐lithium metal battery systems owing to high theoretical capacity, low cost, and intrinsic safety. However, Zn dendrites parasitic side reaction impede its application. Herein, we propose a new principle regulating p ‐band center oxide protective coating balance adsorption energy migration barrier effective deposition stripping. Experimental results calculations indicate that benefiting from...
The chaotropic salt electrolyte (CSE) has become an effective strategy to activate low-temperature aqueous zinc-ion batteries. However, the Zn battery performance been largely compromised due side reaction of active water molecules in CSE. Herein we design a Zn(BF4)2 propylene carbonate–water cosolvent that facilitates zinc plating/stripping wide temperature range (−40 60 °C). Theoretical and experimental results demonstrate dual effect carbonate on regulating hydrogen bond network reshaping...
Aluminum (Al) metal is an attractive anode material for next-generation rechargeable batteries, because of its low cost and high capacities. However, it brings some fundamental issues such as dendrites, Coulombic efficiency (CE), utilization. Here, we propose a strategy constructing ultrathin aluminophilic interface layer (AIL) to regulate the Al nucleation growth behaviors, which enables highly reversible dendrite-free plating/stripping under areal capacity. Metallic can maintain stable on...

In conventional water electrolysis (CWE), the H2 and O2 evolution reactions (HER/OER) are tightly coupled, making generated difficult to separate, thus resulting in complex separation technology potential safety issues.

Here, we propose demonstrate a pH-universal, two-electrode capacitive electrolyzer (referred...
