Lithium sulphur battery specialist Oxis Energy has developed its largest cell yet, said to have an energy density of 300Whr/kg. The company addds that is also increased cell capacity to 25Ahr, which it describes as 'a world first'.
According to Oxis' CEO Huw Hampson-Jones: "Oxis is set to remain at the forefront of the world's leading battery technology with these significant improvement gains. They are being made in partnerships with British and European academic and research institutions, such as LEITAT of Spain, TNO of the Netherlands and the Foundation for Research and Technology in Greece. OXIS is on schedule to release commercial cells for use in applications in the US and Europe in 2015."
The cell capacity of 25Ahr is said to represent a twelve fold improvement in 18 months and Oxis believes it will be able to make a 33Ahr cell by the middle of 2015 and an energy density of 400Whr/kg by the end of 2016.
The company notes that vehicle manufacturers are reviewing and evaluating the cell technology.
