OXIS Energy to build Li-sulfur battery plant in Brazil; initial capacity 2M cells/year

OXIS Energy Ltd UK has signed a contract with CODEMGE PARTICIPACOES SA, a public company incorporated in the city of Belo Horizonte in the state of Minas Gerais, Brazil, to establish the world’s first digital manufacturing plant for the mass production of OXIS’ lithium-sulfur cells.

OXIS Energy Brazil Holdings will manage the plant.

CODEMGE’s US$60-million investment will go towards the building of the plant in Belo Horizonte with Phase 1 having a cell capacity of 2 million cells per annum.

Collaborating with Siemens Digital Factory, among others, the aim is to design a plant that will produce around 5 million cells by the mid-2020s. OXIS expects to complete Phase 1 in 2022.

The OXIS Li-S cells will be developed, designed and produced to meet the demands of three sectors—aviation, defence and electric vehicles such as buses, trucks and light commercial vehicles—reflecting the clients currently in partnership with OXIS.

Li-S allows for a theoretical specific energy in excess of 2700Wh/kg—nearly 5 times higher than that of Li-ion. OXIS’s next-generation lithium technology platform offers the highest energy density among lithium chemistry, with 400 Wh/kg already achieved at cell level. OXIS is targeting 500Wh/kg for 2019.

OXIS is one of the few companies in the world to develop all 3 cell components: The cathode, the anode, and the electrolyte.

OXIS has developed Li-S pouch cells with nominal voltage of 2.1 V and typical capacity of 10 – 35 Ah. OXIS says it will pursue two types of Ultra Light cells (20 Ah, 2.1V) in order to address the specific requirements of aerospace and automotive:

  • High energy density cell (>500 Wh/kg) for small electric aircrafts (2-seater), UAV and High Altitude Pseudo Satellite (HAPS).

  • High power cell (>400 Wh/kg) for automotive applications and electric Vertical Take Off and Landing (eVTOL) aircraft.

Vertical Take Off and Landing (eVTOL) aircraft...
THIS could be interesting.

At 500 Wh/Kg (and above) it would meet one of the future 5-5-5 battery factors required for affordable extended range all weather EVs.

Other electrified vehicles (VTOL, drones, e-planes etc) would also benefit from improved batteries.

This is probably the near future solution to electric mobility as opposed to hydrogen fuel cells which have a long list of problems even if the energy cost of hydrogen was solved.

Judging by the increase in battery research activity presented on this site, there should be many different cell chemistries available by 2022. This being just one.

Hooray! Finally we're seeing advanced chemistries go into commercial production. It will be interesting to see if they can translate their theoretically better chemistry into a commercially viable product.

OXIS is the one company making progress with lithium sulfur, keep going!

Centurion

SJC. Esta usted equivocado, Sion Power esta por delante de Oxis de hecho va a producir celdas de 500wh/kg comercialmente de forma masiva antes que Oxis Energy.

SJC

Sion gave up on sulfur after BASF invested.
