Oxis claims 300Whr/kg for Li-S
Battery specialist Oxis Energy says it has achieved an energy density of 300Whr/kg for lithium sulphur cells and adds that it has increased cell capacity to 25Ahr, which it describes as 'a world first'.
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 reach an energy density of 400Whr/kg by the end of 2016.
