Below is our recent interview with Dr David Ainsworth, CTO at OXIS Energy:
Q: Could you provide our readers with a brief introduction to OXIS Energy?
DA: OXIS Energy is an SME dedicated to commercializing Li-S battery technology and is based near Oxford in the UK. OXIS currently employees around 80 staff, many of whom have scientific and engineering backgrounds.
Q: Your goal is to reach 500 Wh/kg by the end of 2019; how is it even possible?
DA: The Lithium-Sulfur battery system has a theoretical energy density of 2700Wh/kg, although the practical limit is considered to be around 700Wh/kg. This is possible due to the paring of both a high capacity cathode material i.e. sulfur with lithium metal which is the highest capacity negative electrode material known. OXIS has already demonstrated around 450Wh/kg and further optimization of the cell design and materials will allow us to reach 500Wh/kg.
Q: What are the advantages of your cell and battery technology?
DA: The high gravimetric energy density of OXIS Li-S technology will allow applications to either increase range or payload. Additionally the technology will be low cost long term and is more environmentally friendly than current Li-ion batteries due to the absence of cobalt and water based production processes.
Q: Can you give us insights into your products?
DA: OXIS currently produces. high capacity Li-S pouch cells, targeted at aerospace and automotive applications such as e-buses and trucks.
Q: What are your plans for the future?
DA: OXIS will continue to improve its technology in terms on energy density and cycle life, whilst at the same time make the first steps into full scale manufacturing to address key target applications with large blue-chip companies.Activate Social Media:
