Electrodissolution-driven enhancement in Zn electrode reversibility.

Current strategies to enhance Zn reversibility in aqueous Zn batteries (AZBs) primarily focus on inducing planar deposition. However, electrodissolution, as the initial operational step in AZBs, significantly affects deposition behavior and reversibility, yet it is surprisingly overlooked. Herein, the crucial electrodissolution behavior of Zn electrodes and its impact on irreversibility are comprehensively elucidated.

In Situ Visualization of Ion Transport Processes in Aqueous Batteries.

Aqueous rechargeable batteries are regarded as one of the most reliable solutions for electrochemical energy storage, and ion (e.g., H or OH) transport is essential for their electrochemical performance.
