OXIS Energy Confident of Achieving 500Wh/kg with Solid State Lithium Sulfur Technology

OXIS Energy is close to achieving 500Wh/kg and is targeting 600Wh/kg with Solid State Lithium Sulfur technology. The company has successfully tested its cell prototypes at 471Wh/kg and is confident of achieving 500Wh/kg in the next 12 months.

Consistently shipping cells at 400Wh/kg to its clients in Europe, the USA and Japan, OXIS is collaborating with major European chemical partners to develop an advanced lithium metal protection mechanism to ensure a significant improvement in the Lithium Sulfur (Li-S) life cycle.

OXIS has also successfully developed a standard Li-S battery module that saves production time and cost. It is the key building block for customer batteries and can be utilised in electric buses, electric trucks, aircraft and marine vessels.Its main features are:

•Lightweight design – less than 20% of the module is non-cell mass ensuring that the high cell gravimetric energy is harnessed at module level

•Modular design which can be easily scaled into larger batteries •A fire-resistant carbon-fibre enclosure developed with our partners for improved safety

•Compatible with many cooling solutions for effective thermal management

•Designed to minimise assembly time whilst maintaining quality

With demand for its cells increasing two-fold in the next twelve months, the company plans to double its cell production capacity in the UK during 2020. It has already built what is potentially the largest Test Centre in Europe for aircraft and vehicle manufacturers to test Li-S cells and battery systems safely. Its cell technology has already been successfully integrated and ground tested in an aircraft battery system and is scheduled to achieve Technology Readiness Level 9 in flight trials in the USA.
