OXIS Energy Lithium Sulfur
Innovative OXIS Energy is developing a very exciting Lithium Sulfur chemistry. With a theoretical energy density 5 times greater than Li-ion this technology probably will revolutionize the rechargeable battery market. OXIS’ patented Li-S technology is lighter, safer and maintenance free, and ready to meet the demands of tomorrow. Sulfur represents a natural cathode partner for metallic Li and, in contrast with conventional lithium-ion cells, the chemicals processes include dissolution from the anode surface during discharge and reverse lithium plating to the anode while charging. As a consequence, Lithium-Sulfur allows for a theoretical specific energy in excess of 2700Wh/kg, which is nearly 5 times higher than that of Li-ion.
