First principles investigation of zinc-anode dissolution in zinc–air batteries [PDF]

Physical Chemistry Chemical Physics, 2013
With surging interest in high energy density batteries, much attention has recently been devoted to metal-air batteries. The zinc-air battery has been known for more than a hundred years and is commercially available as a primary battery, but recharging has remained elusive, in part because the fundamental mechanisms still remain to be fully understood.

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 ...

Anodes for Zinc Plating

Transactions of The Electrochemical Society, 1932
A study of zinc and zinc alloy anodes for zinc plating was made in both acid and cyanide electrolytes. Alloys of aluminum‐zinc, mercury‐zinc and aluminum‐mercury‐zinc have been compared with “horse head” zinc with respect to their structure, current efficiencies, polarization, sludge formation and solution maintenance. A 0.5 per cent aluminum, −0.3 per

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 ...

Ion-selective and chemical-protective elastic block copolymer interphase for durable zinc metal anode [PDF]

, 2022
Aqueous rechargeable batteries based on zinc anodes are among the most promising systems to replace conventional lithium-ion batteries owing to their intrinsic safety, high ionic conductivity, and economic benefits.

Impact of anode substrates on electrodeposited zinc over cycling in zinc-anode rechargeable alkaline batteries [PDF]

Electrochimica Acta, 2016
Abstract Electrochemical behavior of Ag, Bi, Cu, Fe, Ni and Sn substrates on zinc deposition was evaluated over battery cycling by cyclic voltammetry and electrochemical impedance spectroscopy. The effect of Bi, Cu, Ni, and Sn substrates on zinc electrodeposition during battery cycling was investigated using scanning electron microscopy and X-ray ...

Semi in-situ measurement of zincate ion concentration near zinc anode using background-oriented Schlieren technique

Physical Review Research, 2019
In metal-anode batteries such as zinc, the concentration of metal ions in the electrolyte usually plays a significant role in the metal electrodeposition upon charging.

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition

Advanced Engineering Materials, EarlyView.
AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...
