ABSTRACT

In summary, the integrated conductivity and hydrophilic gradient imprinted gradient zinc anode can effectively inhibit side reactions and regulate zinc deposition behavior, thus achieving long-term cycling under high current/capacity. When multiple materials are composited for use as zinc anode coatings, different structural designs may have a dramatic effect on the electrochemical performance, even though the components are the same. The gradient imprinted design and related analysis method can be applied to other zinc anode coating materials, which will contribute to the design of future AZIBs. Moreover, at high current density/capacity, other metal-anode secondary batteries (e.g., lithium-ion batteries, sodium-ion batteries, aluminum-ion batteries, etc.) almost always suffer from serious dendrite problems, and thereby this work can also provide new research inspiration.
