Electrical‐Conductive/Insulating Bi‐Functional Layers for Stable Zn Metal Anode

Chemistry – A European Journal, 2022
AbstractZinc‐ion batteries are regarded as an extremely promising candidate for large‐scale energy storage equipment due to the inexpensive ingredients and high safety. However, dendrite growth and side reactions occur in the Zn anode, which lead to exceedingly low coulombic efficiency (CE) and poor cycling stability.

ZnO Nanoparticle Assisted Liquid Metal for Dendrite‐Free Zn Metal Anodes

Small
AbstractDendrite growth and interfacial side reactions on Zn anode seriously affect the safety and service life of Zn ions batteries. Interface engineering is an effective way to solve these problems. Here, a liquid metal‐ZnO composite coating with high ionic conductivity is creatively designed, which not only reduces the Zn2+ diffusion barrier but ...

Efficient Zn Metal Anode Enabled by O,N-Codoped Carbon Microflowers

Nano Letters, 2022
Zinc metal anodes show great promise for cheap and safe energy storage devices. However, it remains challenging to regulate highly efficient Zn plating/stripping under a high depth of discharge (DOD). Guided by density functional theory calculation, we here synthesized an oxygen- and nitrogen-codoped carbon superstructure as an efficient host for high ...

Tailoring the Electrode Interface Microenvironment to Stabilize Zn Metal Anode

Small
AbstractZn metal is the most attractive anode material for aqueous batteries, yet it encounters challenges from dendrites. Here, based on lanthanum trifluoromethanesulfonate (La(OTf)3)‐based electrolyte, the idea of tailoring the electrode interface microenvironment (ion concentration, solid electrolyte interphase (SEI) and electric field) is proposed ...

Synergistic Anion–Cation Chemistry Enables Highly Stable Zn Metal Anodes

Journal of the American Chemical Society
Engineering aqueous electrolytes with an ionic liquid (IL) for the zinc (Zn) metal anode has been reported to enhance the electrochemical performances of the Zn metal batteries (ZMBs). Despite these advancements, the effects of IL and the mechanisms involving their anions and cations have been scarcely investigated.

Kinetics‐Mediating Artificial Interphase for Ultrafast Zn Metal Anodes

Advanced Functional Materials
AbstractAchieving long‐term cycling stability of Zn metal anodes at high rates is crucial for the practical applications of aqueous Zn ion batteries. However, the sluggish kinetics of Zn deposition and uncontrollable dendrite growth at the electrolyte/electrode interface will inevitably lead to inferior energy efficiency and limited cycling lifespan ...
