OXIS Energy’s patented technology is at the cutting edge of Li-S battery development. Its Li-S batteries are lighter, safer, and have a theoretical energy density five times greater than conventional lithium-ion batteries.

Using its proprietary plasma technology, Perpetuus is able to insert molecules into layered solids such as graphene (known as intercalation) to the very high levels required for enriched electrode materials. Together with OXIS Energy technology, these advanced electrode materials will deliver the next generation of high-performance batteries, offering energy densities on the order of 400 Wh/kg.

This is significantly higher than current Li-ion batteries can achieve. It is also much more cost-effective, as it will enable battery electric vehicles (BEVs) to undertake journeys of 400–500 miles (640–800 km) on one battery charge.

‘There is no doubt that OXIS Li-S technology has the ability to be significantly superior to current Li-ion batteries,’ says John Buckland, CEO of Perpetuus. ‘I hope this collaboration will pave the way for the UK to be the centre of Li-S battery manufacturing.’
