Battery manufacturer Oxis Energy has developed a lightweight lithium sulphur prototype cell for power management company Lincad and the UK Ministry of Defence.

The prototype cell is the result of the third programme phase of the Defence Science and Technology Laboratory research programme.  The cell provides a 60% increase over the capacity achievement in phase 2 in 2013 and increases the specific energy of a cell to just under 300Wh/kg, according to Oxis Energy.

OXIS Energy, UK, and GP Batteries, of Singapore, are embarking on a joint manufacturing project to make lithium-sulphur (Li-S) battery systems on a commercial scale for use in defence, automotive and solar panel markets.

The joint venture is expected to accelerate the Li-S cells and battery system to a commercial scale, as made by OXIS and mass produced by GP Batteries. OXIS has been developing the Li-S batteries since 2004 for the broad electric vehicle market as well as aviation and defence applications.

"Lithium-sulphur polymer batteries could well be the long sought after technology which will correct many of the deficiencies and shortcomings of the present generation of lithium-ion batteries, such as safety", said GP Batteries Chairman and Chief Executive Andrew Ng.

OXIS and GP Batteries are establishing a joint board to review the developments and improvements in the emerging technology for presentation to customers.
