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 module that it says saves production time and cost. The module was designed to be utilized in electric buses, trucks, aircraft and marine vessels. It features a fire-resistant carbon-fiber enclosure, modular design, and less than 20 percent non-cell mass.

OXIS plans to double its cell production capacity in the UK in 2020 and has built a test center in Europe for aircraft and vehicle manufacturers to test Li-S cells.

Huw Hampson-Jones, CEO of OXIS Energy, said, “OXIS continues to focus on the aerospace, defense, marine vessels, and heavy electric vehicles market sectors where weight reduction, elimination of distance anxiety and safety are of paramount importance. The culture of early adoption of new technology, which characterizes the ‘can do’ attitude of US business, is driving the implementation of OXIS Li-S cell and battery systems across multiple markets. The US and Japan are emerging as key new entrants in the use of Li-S cells and battery systems.”
