Solid-state lithium-sulfur technology close to achieving 500Wh/kg

OXIS Energy has tested its cell prototypes at 471Wh/kg and is confident of delivering 500Wh/kg in the next 12 months.

The company is collaborating with major European chemical partners to develop an advanced lithium metal protection mechanism to guarantee a significant improvement in the Li-S life cycle.

The company has also successfully developed a standard Li-S battery module that reduces production time and cost. It is the main building block for batteries for customers and can be employed in electric buses, electric trucks, aircraft and marine vessels.

Huw Hampson-Jones, CEO OXIS Energy, said, “OXIS continues to focus on the aerospace, defence, 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 characterises the 'can-do' attitude of US business is driving the implementation of OXIS Li-S cell and battery systems across multiple markets. The United States and Japan are emerging as key new entrants in the use of Lithium Sulfur cells and battery systems.”
