The next generation battery technology company, OXIS Energy Ltd has delivered the second phase of a research programme that it’s working on in collaboration with Lincad Ltd to improve its Lithium Sulfur batteries. The project is part of a wider Dstl (Defence Science and Technology Laboratory) research programme which is looking to develop significantly lighter and safer batteries for UK armed forces.
Dstl has divided the OXIS part of the research programme into three parts. Phase one demonstrated the cells and their chemistry and was successfully completed last year. Phase two was to improve the cells and integrate them into two reduced functionality concept batteries – i.e. same size and shape as in-service batteries which OXIS has now successfully completed and delivered to Lincad Ltd.
During the course of this project, OXIS has made improvements to its cell chemistry to boost performance and demonstrated the impressive safety record of Li-S batteries. For example, when punctured by nails or bullets no adverse reaction was observed. OXIS has also modified its cell design as part of this project to meet the bespoke requirements of the MoD battery and has worked with Lincad Ltd in order to integrate this with a new, highly robust Battery Management System (BMS) in order to bring further reliability improvements to the batteries.
Lincad Ltd Project manager, Quintin Moore said, “We are really excited at the progress that has been made on this Lithium Sulfur project in the past 12 months. It is a major achievement in that we have been able to meet the objectives for this phase of the project in such a short time frame. Lincad is looking forward to working with OXIS Energy and the MoD on the next phase of this project to complete the development of the next generation lightweight, safe Lithium Sulfur power source which will help reduce the soldier burden for UK Forces.’
The concept demonstrator batteries that OXIS and Lincad have jointly delivered to Dstl will be thoroughly tested in Dstl’s laboratories and will provide valuable data for the next stage of the programme which is ultimately to develop full capability LI-S batteries for field testing that are lighter than in-service batteries and whilst maintaining the high safety standards already achieved.
OXIS Energy Chief Executive Officer, Huw Hampson-Jones said, “We are moving on apace and are extremely pleased with our progress so far. We are absolutely thrilled at the results achieved. OXIS is looking forward to working with Lincad and the MOD to develop Li-S batteries into world leading equipment for UK forces.”
