Stable cycling of high-voltage lithium metal batteries in ether electrolytes

Dendrite-Free Lithium Deposition via Self-Healing Electrostatic Shield Mechanism

Rechargeable lithium metal batteries are considered the "Holy Grail" of energy storage systems. Unfortunately, uncontrollable dendritic lithium growth inherent in these batterie...

High‐Voltage Lithium‐Metal Batteries Enabled by Localized High‐Concentration Electrolytes

Abstract Rechargeable lithium‐metal batteries (LMBs) are regarded as the “holy grail” of energy‐storage systems, but the electrolytes that are highly stable with both a lithium‐...

Nitrogen‐Coordinated Single Cobalt Atom Catalysts for Oxygen Reduction in Proton Exchange Membrane Fuel Cells

Abstract Due to the Fenton reaction, the presence of Fe and peroxide in electrodes generates free radicals causing serious degradation of the organic ionomer and the membrane. P...
