OXIS ENERGY LIMITED

Their core work

OXIS Energy is a UK-based battery technology company specializing in lithium-sulphur (Li-S) cell development and manufacturing. They develop advanced battery chemistries as an alternative to conventional lithium-ion, targeting electric vehicle and space applications. Their work spans the full battery engineering chain — from electrode materials (anodes, solid-state electrolytes, membrane separators) to cell-level safety and manufacturing processes. They contribute specialist Li-S cell expertise to European research consortia developing next-generation energy storage.

What they specialise in

How they've shifted over time

Early work (2015–2017) focused on fundamental Li-S cell engineering — sputtering, plasma processing, ionic liquid electrolytes, and electrospinning for membrane separators — across both automotive (ALISE) and space (ECLIPSE) applications. By 2019, the focus shifted decisively toward automotive-ready traction batteries with an emphasis on solid-state electrolytes, lithium anode protection, CRM-free materials, and sustainable manufacturing. The evolution shows a clear trajectory from laboratory-scale materials research toward production-oriented, application-specific battery engineering.

OXIS was moving toward production-ready, CRM-free lithium-sulphur batteries for electric vehicles with a growing emphasis on sustainable manufacturing — though their H2020 activity ended in 2019 and the company's current operational status should be verified.

How they like to work

OXIS Energy participated exclusively as a partner, never coordinating — consistent with a specialist technology provider contributing proprietary Li-S cell expertise to larger consortia. With 35 unique partners across 9 countries from just 3 projects, they operated in sizeable, diverse consortia typical of ambitious Research and Innovation Actions. This profile suggests they are a sought-after specialist rather than a project initiator, contributing deep domain knowledge to multi-partner efforts.

Built a network of 35 partners across 9 countries through three RIA projects, indicating they collaborate with large, geographically diverse consortia. Their partnerships span automotive OEMs, materials research institutes, and space agencies across Europe.

What sets them apart

OXIS Energy was one of very few European companies focused exclusively on lithium-sulphur battery technology — a chemistry that offers significantly higher energy density than lithium-ion while avoiding cobalt and nickel. Their rare combination of Li-S expertise across both space and automotive sectors made them a distinctive partner for projects requiring next-generation energy storage beyond conventional Li-ion. For consortium builders, they offered a specialist perspective on post-lithium-ion battery chemistries that few other private companies in Europe could match.

Highlights from their portfolio

• ALISE
  Largest project by funding (EUR 952K), covering the full Li-S battery engineering chain from electrode fabrication to safety for electric vehicles.
• ECLIPSE
  Unusual cross-sector reach — applied Li-S battery technology specifically to space environments, demonstrating versatility beyond automotive.
• LISA
  Most recent project, marking a strategic shift toward CRM-free, sustainable battery manufacturing for road electrification.
