With lithium in short supply, a new alternative for batteries is needed to meet growing global demand. Calcium offers an option that is both higher in capacity and safer than lithium. With a valency of 2, calcium can offer double the electrons that lithium can and provide a higher capacity battery. It also has the potential for use with metallic anodes for increased energy density. 

Factors impeding the use of calcium include difficulty finding a suitable electrolyte for use with a calcium metal anode. Researchers struggle to find a method for reversible uptake and release of calcium. This new study poses an electrolyte that could provide the solution needed.
