Gelion signs co-funded proof-of-concept pilot with top-five global automaker to test NES sulfur cathode

A top-five automaker puts Gelion's sulfur cathode to the test

Australian battery materials developer Gelion has entered a co-funded proof-of-concept agreement with a top-five global automotive original equipment manufacturer to jointly test and evaluate its Nano-Encapsulated Sulfur (NES) cathode active material under conditions relevant to electric vehicles. MarkLines reports the agreement was signed on 13 October 2026, with the identity of the OEM and any production application not disclosed. ¹

Automotive World, citing Gelion, reports that this is the first co-funded OEM evaluation of cells pairing NES with a graphite anode. The partner will contribute engineering support, battery test facilities and part of the programme funding, while Gelion runs parallel tests to correlate results. The automaker's name, the programme's value and its timeline were not disclosed. ²

Proactive, via Yahoo Finance, reports that Gelion told investors the unnamed automaker will contribute funding, engineering expertise and advanced testing facilities to the proof-of-concept programme, which will evaluate the NES cathode material in battery cells using conventional graphite-based anodes. ³

What Gelion says the technology offers

Gelion positions NES as a drop-in cathode for existing battery cell production lines, suited to standard anodes and electrolytes, according to Automotive World. The technology is designed to replace critical minerals in lithium-ion battery cathodes with cheaper and more abundant sulfur, potentially allowing manufacturers to adopt it without major retooling, as reported by Proactive through Yahoo Finance. ²³

In a statement carried by Automotive World, Gelion chief executive Matt Wood said: "This agreement with a top 5 global automotive manufacturer marks a major milestone in the validation of our NES cathode material." He added that combining Gelion's materials expertise with the OEM partner's engineering capability and battery testing facilities provides an opportunity to demonstrate the material's performance and manufacturability for demanding automotive applications. ²

Speaking to Proactive in an interview published on Yahoo Finance, Wood described the technology as high-capacity, high-power cathode material that is cheaper and lighter than incumbent materials, with potential to support lower-risk domestic supply chains. These are the chief executive's own claims rather than independently verified performance findings. ⁴

The second OEM agreement in a week

The proof-of-concept deal follows a separate material transfer agreement announced by Gelion on 6 October 2026 with a different unnamed partner, this one a top-15 global automaker. Automotive World reports that under that agreement, Gelion will supply sulfur-based active cathode material, coated cathodes and a liquid electrolyte for evaluation in both liquid and solid electrolyte cell configurations, using lithium metal or graphitic anodes, targeting luxury and mass-market EV applications. The deal covers evaluation only, with no supply terms, licence or partner name disclosed. ⁵⁷

MarkLines' Chinese-language service likewise reported the 6 October agreement, stating that the OEM partner would be able to evaluate the NES cathode platform across future EV battery configurations, with Gelion supplying sulfur-based cathode active material, coated cathodes and liquid electrolyte for liquid and solid electrolyte setups aimed at both luxury and volume-production EVs. ⁸

In the statement reported by Automotive World, Wood said Gelion was "honoured to be working with these major global automotive OEMs", describing the agreements as progress towards commercial revenue via funded programmes and, eventually, licence and royalty revenue in the global EV market. The company also said other leading OEMs are assessing the chemistry. ⁵

Breadth of automotive interest, per the chief executive

In his Proactive interview, Wood framed the new agreement as building on recent progress, including the top-15 OEM agreement announced the previous week and a solid-state battery programme with Nissan in Europe announced in June. He said there is growing breadth and depth of automotive interest, with more companies evaluating Gelion's cathode materials across different chemistries and applications, from luxury to mass-market EVs. He also indicated the OEM pilot would bring modest additional commercial revenue in 2027, alongside revenue from a joint development agreement with Mitsubishi announced in August. These figures and projections come from the chief executive and should be treated as company statements rather than confirmed outcomes. ⁴

Beyond EVs, Wood told Proactive that Gelion's wider strategy spans defence and aerospace, consumer electronics and electric vehicles, referencing recent drone mission testing results from the ARMD programme with QinetiQ. The company's own website lists its priority markets as commercial and defence drones, EVs and devices. ⁴⁵

Context: the Nissan and Oxford solid-state programme

The pilot adds to an established UK collaboration. According to Gelion's own website, the company, Nissan Technical Centre Europe and the University of Oxford are partners in a three-year project called CoRe-SoLiS (Cost-effective, Resilient Solid-state Li–S), a £3.4 million programme commencing in June 2026 and supported by £2.4 million in grant funding from Innovate UK, of which Gelion's UK subsidiary was awarded £1.6 million. The project combines Gelion's sulfur cathode technology with solid-state battery architectures, aiming for higher-performance, lower-cost EV battery solutions. ⁶

Gelion's broader partner network, as listed on its website and in reporting sourced to the company, includes TDK and Mitsui Kinzoku in Japan, QinetiQ and Nissan UK in the United Kingdom, the National Laboratory of the Rockies in the United States and the Max Planck Institute of Colloids and Interfaces in Germany. ⁷⁶
