Project CaSino investigating calcium-sulfur batteries

Green Car Congress

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. However, lithium-based systems have an increased risk of fire, as dendrites can form with repeated charging, which in the worst case lead to an internal short circuit.

New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

Sadoway considers this development a breakthrough, because for the first time in five decades, this type of battery—the advantages of which include cheap, abundant raw materials, very safe operational characteristics, and an ability to go through many charge-discharge cycles without degradation—could finally become practical.
