Development of Rechargeable Monopolar and Bipolar Zinc/Air Batteries

CHIMIA, 1995
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepared and tested in monopolar zinc/air cells. In addition, a bipolar Zn/air stack was

A Quasi‐Solid Ionic Liquid‐Polymer Hybrid Electrolyte for Shuttle‐Free and Dendrite‐Free Aqueous Zinc─Bromine Batteries

Advanced Materials, EarlyView.
A quasi‐solid ionic liquid‐polymer hybrid electrolyte is proposed to achieve shuttle‐free and dendrite‐free aqueous Zn─Br batteries. Synergetic effects between Zn2+ selective conduction of polyanionic network and polybromide complexing additive suppress the shuttle effect and improve Zn reversibility.

Navigating Ternary Doping in Li‐ion Cathodes With Closed‐Loop Multi‐Objective Bayesian Optimization

Advanced Materials, EarlyView.
The search for advanced battery materials is pushing us into highly complex composition spaces. Here, a space with about 14 million unique combinations is efficiently explored using high‐throughput experimentation guided by Bayesian optimization with a deep kernel trained on both the Materials Project database and our data.
