OXIS says its lithium-sulfur battery is close to achieving 500 Wh/kg

OXIS Energy has successfully tested its lithium-sulfur (Li-S) battery cell prototypes at 471 Wh/kg. The company said it expects to achieve 500 Wh/kg in the next 12 months. OXIS research scientists think they can extend both gravimetric and volumetric energy density towards 600 Wh/kg and over 800 Wh/L. OXIS has also developed a standard Li-S battery… Read more »

IBM and Daimler claim quantum leap in lithium-sulfur battery breakthrough

Electric vehicles may be the wave of the future, but each machine is only as good as its battery. A breakthrough in quantum computing from a Daimler-IBM collaboration may change the way we think about the power of lithium. Researchers are one step closer to creating cheaper, more powerful, longer lasting batteries accessible to a… Read more »
