Self-repairing interphase reconstructed in each cycle for highly reversible aqueous zinc batteries

Nature Communications, 2022
Metallic zinc is an ideal anode material for aqueous rechargeable batteries but reversibility is a challenge. Here, the authors realise a dynamic real-time reconstructed interphase on zinc anode formed by graphitic carbon nitride quantum dot as an ...

A lean‐zinc anode battery based on metal–organic framework‐derived carbon

Carbon Energy, 2023
Improving zinc metal (Zn0) reversibility and minimizing the N/P ratio are critical to boosting the energy density of Zn0 batteries. However, in reality, an excess Zn source is usually adopted to offset the irreversible zinc loss and guarantee sufficient ...

Long-Chain Molecule Reconstruction of Novel Solvation Structure to Stabilize Zinc Metal Anode. [PDF]

Adv Sci (Weinh)
Triethylene glycol diacetate (TGD), with unique long‐chain characteristics and rich oxygen‐containing functional groups, was used as an electrolyte additive to reconstruct the solvation structure. TGD can reduce the erosion of H2O molecules on the Zn anode, effectively homogenize the electric field distribution. Therefore, the Zn//Zn symmetric cell can

Gradient design of imprinted anode for stable Zn-ion batteries

Nature Communications, 2023
Zinc metal anodes suffer from electrolyte corrosion and dendrite growth issues during electrochemical cycling. Here, the authors propose a gradient design to imprint the zinc anode, which both prohibits side reactions and alleviates zinc deposition ...

Corrosion as the origin of limited lifetime of vanadium oxide-based aqueous zinc ion batteries

Nature Communications, 2022
Aqueous zinc ion batteries are good systems for large-scale energy storage. Here, the authors report that the corrosion of zinc metal anode is the origin of limited lifetime of vanadium oxide-based aqueous zinc ion batteries, and supressing corrosion ...
