A diverse set of applications.

Our applications are described in more detail below along with the grant funded projects that support this work.

Key features
  • Ultra-lightweight
  • Perfect for HALE UAVs
  • Enables electric aircraft
  • Also suitable for space sector

Aviation

Weight is of the utmost importance in aircraft. The heavier they are, the more energy is needed to keep them airborne. OXIS has developed batteries that are significantly lighter than any Li-ion solution.
OXIS is developing a <30 kWh battery system integrated with an Aviation Battery Management System for a two-seater electric passenger aircraft.
OXIS will be instrumental in moving the aviation sector away from lead-based fuel and more importantly will extend the flight time four-fold without any increase to aircraft weight.
Our expertise in developing battery solutions for use in electric aerospace propulsion, makes vertical take-off and landing (VTOL) for passenger electric aircraft, a reality.
We have also secured a contract to develop an even larger prototype battery for commercial aviation.

Key features
  • Ultra low temperature operation
  • High specific energy

Aeronautical  

OXIS and NASA are developing high specific energy Li-S cells for weight crucial applications such as drones and high altitude vehicles.
OXIS will supply its Ultra Light cells to NASA’s JPL Laboratory for evaluation under different conditions at its facility in Pasadena, California.
Energy density, low temperature performance, cycle life, self-discharge and calendar life will be assessed.
Along with several European and US companies OXIS is developing high altitude UAVs and other aerospace applications such as stratospheric balloons.
OXIS has also secured a grant to develop a 425Wh/kg cell as part of the Aerospace Technology Institute Zephyr Innovation Program with Airbus Defence and Space. The goal to achieve and maintain uninterrupted performance whilst increasing the operational range.
This will allow UAVs to provide interconnectivity services to the developing world and help bring two billion people online.

Key features
  • Lightweight
  • Safe
  • Maintenance free
  • 100% Depth-of-Discharge

Lightweight batteries reduce the load on soldiers.

Most batteries completely shut down and fail to work at low temperature. Components freeze over thus preventing the chemical reaction.
A high energy density cell is essential in this environment.
OXIS, Hyperdrive Innovations and the British Antarctic Survey (BAS) have completed the Ultra Low Temperature Battery (ULTB) project, developing a Li-S cell that can operate at -60°C at the South Pole meeting BAS requirements.
The Li-S battery system is up to 74% lighter at system level than BAS’s current application. Lighter batteries allows BAS scientists to carry much more equipment. This will increase reliability and reduce mission costs.
OXIS has also developed a prototype lightweight, portable battery pack to enable soldiers to power crucial communication and IT equipment.
The technology is able to withstand bullet and nail penetrations with no adverse reactions or significant rise in temperature.

Key features
  • Lightweight
  • Low cost
  • Safe

The two largest challenges to the mass adoption of electric vehicles are range anxiety and safety.

Heavy Electric Vehicles
The Lithium Sulfur Future Automotive Battery (Li-S:FAB) project, led by OXIS Energy and funded by Innovate UK will help to transform electric vehicle technology for commercial use. It will develop a next generation cell and module that is suitable for large electric vehicles such as trucks and buses and will deliver a 400 Wh/kg Li-S cell that will have the significantly improved power and cycle life required for large automotive applications.
This cell will allow buses and trucks to carry considerably more payload and will cost less because of the abundant cell construction materials. State of Charge and State of Health (SoC and SoH) will be improved, along with the manufacturing aspect. OXIS will play a key role in ‘Cell Manufacturability’. It will help develop crucial pouch cell sealing technology required to make a robust automotive cell.
We specifically target the South America and China where the need to electrify diesel powered buses is the most pressing.
Light Electric Vehicles
In the Advanced Lithium Sulfur for xEV (ALISE) project, OXIS is working with Leitat, SEAT and twelve other partners to develop 400Wh/kg and 500Wh/kg cells for Battery Electric Vehicle (BEV) and plug-in hybrid electric vehicle (PHEV).
Along with our partners, we conduct extensive material research to increase the energy density, power performance and cycle life of the cells. The project is funded by the European Commission.
In another successful assignment, the Revolutionary Electric Vehicle Battery (REVB) project, co-funded by Innovate UK, OXIS has successfully completed its research into developing a 400Wh/kg cell for a battery electric vehicle (BEV). OXIS worked with Imperial College London to develop electrochemical models of the chemistry and with Cranfield University and Ricardo to develop control models and a demonstration battery pack respectively.
Having been selected for other grant funding programmes, OXIS continues to develop world leading simulation models of the chemistry.

Key features
  • Lightweight
  • Safety

Solar energy storage has become a rapidly growing market, the key driver for which is the need to reduce energy bills.

Energy Storage has become a rapidly growing market, driven by an increasing share of renewable energy generation. This changing mix of energy production has created new problems to ensure grid supply and minimise electricity bills. Energy Storage provides an effective solution for grid stabilisation, power generation management and residential storage. Industry and consumers want a cost effective solution that is safe, easy to install with minimal maintenance.

OXIS Li-S technology offers the perfect solution to these problems. OXIS has already built and proven prototype batteries for these application. The OXIS Rack Mount Battery (RMB) is a 3 kWh 48V unit that can be used individually or scaled to large MWh solutions.

Key features
  • Lightweight
  • Naturally Buoyant
  • High Energy Density
  • Pressure Tolerant

Marine

Li-S technology not only offers increased specific energy but also increased safety and lower mass density of the cells. This constitutes a major development for the powering of Autonomous Underwater Vehicles (AUVs), in particular those systems that require longer endurance and higher speeds at greater depth.
OXIS Energy, Steatite, MSubs and the National Oceanography Centre (NOC) have developed a pressure tolerant Li-S battery that is capable of powering marine autonomous vehicles to depths of over 6,000 metres.
The cells can withstand the extreme pressure at temperatures of 4° without being compromised on integrity.
Due to the neutral buoyancy of the cells nad battery, buoyancy foam can be reduced in the vehicle, saving cost, weight and volume.
Li-S technology serves all deep-sea mining and offshore oil and gas applications, where energy density is a factor.
