OXIS steadily boosts energy density of its lithium sulfur cells

Battery developer OXIS Energy has created a 425 Wh/kg, 16 Ah lithium sulfur (Li-S) cell for High Altitude Pseudo Satellites (HAPS), and is working towards a 450 Wh/kg cell design at the end of this year. The company has its sights set on 500 Wh/kg by the end of 2019.

“At 425 Wh/kg, OXIS has one of the lightest pouch cells currently available and is already attracting significant interest from major players in the aerospace sector. The cell is about to go into prototype applications,” says OXIS CTO Dr. David Ainsworth.

OXIS has also developed a prototype aviation battery that it claims has enabled customers to increase flight time threefold. The battery module uses a lithium sulfur pouch cell with specific energy of 300 Wh/kg.

Huw Hampson-Jones, CEO of OXIS, said the company has invested $10 million to develop lithium sulfur cells for electric buses and trucks. He also took a little dig at Tesla: “In many ways, over the course of the next 2-3 years with commercial development, technological achievements as well as the mass production of lithium sulfur cells coming on stream, the case for investing in lithium-ion gigafactories is a fool’s paradise.”

    Lithium Metal Batteries are the wave of the future. But Sulfur could keep things interesting.

      the low volunetric energy density pulling back this tech from electric vehicles…lithium dendrites and scarcity are other scientific challenges along with polysulfide dissolution..fingers crossed.

    You can get cycles or density but not both.

    I do not understand how OXIS energy density is less than 21700 Tesla cells

    • SJC

      425 Wh/kg is much higher than Panasonic.

    Is someone attempting to imdisfrialise the Lithium Sulfur solid state cell from Goodenough

    • SJC

      He has a solid cell, not sulfur.

    Fools is what people that makes money like to be called…. That´s what an entry barrier should do…. We will see when they sell megavolumes… They keep building megafactories for ICE vehicles, nobody calls them fools, like they did to H. Ford
