In situ formation of solid electrolyte interphase facilitates anode-free aqueous zinc battery

eScience
Aqueous Zn batteries (AZBs) suffer from poor Zn anode reversibility. To address this issue, excess Zn foil is often utilized to prolong the cycle life, but it reduces the actual battery energy density. In this work, we use methylurea molecules to in situ

Anode corrosion in aqueous Zn metal batteries

EScience, 2023
Given their low cost and intrinsic safety, aqueous Zn metal batteries (AZMBs) are drawing increasing attention in the field of smart grids and large-scale energy storage. However, the Zn metal anode in aqueous electrolyte suffers from a critical issue, corrosion, which must be fully addressed before the practical implementation of AZMBs.

Construction of Microporous Zincophilic Interface for Stable Zn Anode. [PDF]

Molecules, 2023
Aqueous zinc ion batteries (AZIBs) are promising electrochemical energy storage devices due to their high theoretical specific capacity, low cost, and environmental friendliness. However, uncontrolled dendrite growth poses a serious threat to the reversibility of Zn plating/stripping, which impacts the stability of batteries. Therefore, controlling the

Gel Electrolyte Constructing Zn (002) Deposition Crystal Plane Toward Highly Stable Zn Anode. [PDF]

Adv Sci (Weinh), 2022
AbstractZinc (Zn) metal anode has been widely evaluated in aqueous Zn batteries. Nevertheless, the dendrite formation issue and consecutive side reactions severely impede the practical applications of Zn metal at high current densities. Herein, it is reported that engineering the gel electrolyte with multifunctional charged groups by incorporating a ...

An Anode‐Free Zn–Graphite Battery

Advanced Materials, 2022
AbstractThe anode‐free battery concept is proposed to pursue the aspiration of energy‐dense, rechargeable metal batteries, but this has not been achieved with dual‐ion batteries. Herein, the first anode‐free Zn–graphite battery enabled by efficient Zn plating–stripping onto a silver‐coated Cu substrate is demonstrated. The silver coating guides uniform

Electrolyte Additives for Stable Zn Anodes

Advanced Science, 2023
AbstractZn‐ion batteries are regarded as the most promising batteries for next‐generation, large‐scale energy storage because of their low cost, high safety, and eco‐friendly nature. The use of aqueous electrolytes results in poor reversibility and leads to many challenges related to the Zn anode. Electrolyte additives can effectively address many such

Reversible Zn/polymer heterogeneous anode

Carbon Energy, 2023
AbstractCommercialization of Zn‐metal anodes with low cost and high theoretical capacity is hindered by the poor reversibility caused by dendrites growth, side reactions, and the slow Zn2+‐transport and reaction kinetics. Herein, a reversible heterogeneous electrode of Zn‐nanocrystallites/polyvinyl‐phosphonic acrylamide (Zn/PPAm) with fast ...

An Anode-Free Zn–MnO₂ Battery

Nano Letters, 2021
Aqueous Zn-based batteries are attractive because of the low cost and high theoretical capacity of the Zn metal anode. However, the Zn-based batteries developed so far utilize an excess amount of Zn (i.e., thick Zn metal anode), which decreases the energy density of the whole battery.
