At the forefront of developing Li-S cell and battery technology 

Our history

OXIS has developed its unique technology around sulfur based cathode materials, highly stable electrolyte systems and anode made of Lithium metal and intercalation materials.

We are based on the Culham Science Centre in Oxfordshire where the original Lithium-Ion batteries were first developed and prototyped. We have well equipped laboratories with state of the art equipment and large dry room facilities.

OXIS and its research partners are focusing on the development of the world leading Li-S chemistry that can be used in many battery applications. Mass production of the cells is handled by our manufacturing plants in Brazil and in the UK.

OXIS is a member of RECHARGE, a non profit organization founded to promote the value of rechargeable batteries and represent the interests of all its members in the chain of battery life.

OXIS has completed full registration with the US government under the SAM.Gov Scheme and as such we are able to let our customers and government procurement officers know that we are registered as the US Federal Contractor Registration Verified Vendor

OXIS Energy will be featured as one of the Sunday Times BGF 10 Green Tech to Watch in the 20th anniversary edition of the Sunday Times Tech Track 100.

OXIS Patent Portfolio

OXIS has 41 patent families with 200 patents granted and 110 pending. The patents cover electrolyte systems for lithium sulfur cells, methods of lithium sulfur cell construction and also positive and negative electrodes. The patent portfolio is rapidly growing and it reflects the success of our research and development programme.
