Electrode Materials for Li-ion Batteries

Solid oxide fuel cells and electrolyzers show potential for chemical-to-electrical energy conversion, despite early development stages.

Recent Developments in Silicon Anode Materials for High Performance Lithium-Ion Batteries

Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Safer High-performance Electrodes, Solid Electrolytes, and Interface Reactions for Lithium-ion Batteries

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.
