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. Magnesium is substantially more abundant than lithium, which should meet the needs of the ever-growing battery market.
