UMD, Army Researchers design new electrolyte enabling high energy density rechargeable Mg and Ca batteries

Green Car Congress

Rechargeable magnesium and calcium metal batteries (RMBs and RCBs) are promising alternatives to lithium-ion batteries because of the high crustal abundance and capacity of magnesium and calcium. A paper on their work is published in the journal Science. Yet, they are plagued by sluggish kinetics and parasitic reactions.

U Maryland team devises new method to stabilize high-capacity Si anodes for Li-ion batteries: interfacial oxygen

Green Car Congress

Researchers at the University of Maryland have improved the cycle life of silicon/carbon matrix-composite electrodes by 300%, even at mass loadings, solely by the chemical tailoring of the interface between the silicon and the carbon with atomic oxygen. Interfacial oxygen between the silicon and carbon improves electrode performance.
