Project CaSino investigating calcium-sulfur batteries

Green Car Congress

The joint European project “CaSino” is investigating the potential of the calcium sulfur (Ca-S) battery as an alternative to lithium-ion batteries. Lithium is a stellar element for an electrochemical cell in many ways—it combines a high power storage capacity and cell voltage with fast ion migration.
