OXIS Energy claims its lithium sulphur cells are the next generation of battery technology, surpassing Lithium-ion which is reaching the limit of its potential. Now it’s gone further and is collaborating with Perpetuus in the development of graphene-enabled electrodes for the next generation of lithium sulfur (Li-S) battery technology.
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 is expected to deliver the next generation of high performance batteries offering energy densities in the order of 400 watt-hours per kilogramme.
This is significantly higher than current Li-ion batteries can achieve. It is also much more cost effective as it will enable cars to undertake journeys of 400-500 miles on one battery charge.
Commenting on the collaboration, Huw Hampson Jones, CEO of OXIS said, “Perpetuus has a unique ability to produce industrial quantities of the nano engineered electrode materials that will significantly extend the cycle life of Li-S batteries.”
John Buckland, Perpetuus CEO, agreed. He said “There is no doubt that OXIS Li-S technology has the ability to be significantly superior to current Li-ion batteries. I hope this collaboration will pave the way for the UK to be the centre of Li-S battery manufacturing. Perpetuus plasma technology could ensure the UK becomes the manufacturing centre to a vast number of graphene-enabled products over the next few years. In the coming months, we hope to be announcing further collaboration and development agreements with other UK businesses utilising our nano surface engineered graphene materials.”
