Li-S Battery Storage Anesco Ltd. (Reading, U.K.; www.anesco.co.uk) and OXIS Energy (Abingdon, U.K.; www.oxisenergy.com) have begun a collaboration to commercialize OXIS Lithium Sulfur Technology for battery storage for commercial and residential renewable installations. The new battery storage units will be available for installation from 2016. OXIS’ Li-S cells are composed of a metallic Li anode, a sulfur-based cathode (which includes carbon and a polymer binder) and a non-flammable electrolyte, which renders the cell inherently safe, says the company. In contrast with conventional Li-ion cells, the chemical processes include dissolution from the anode surface during discharge and reverse lithium plating to the anode while charging. As a consequence, Li-S allows for a theoretical specific energy in excess of 2,700 Wh/kg, which is nearly five times higher than that of Li-ion, says OXIS. The company has already demonstrated the technology in “pouch cells” with specific energy of 300 Wh/kg.
