Gelion Lands Second Automaker Battery Deal in a Week, This Time With a Global Top-Five OEM

Australian battery materials developer Gelion has secured a jointly funded proof-of-concept agreement with an unnamed automaker ranked among the world’s five largest, as the company pushes to prove that its nano-encapsulated sulfur (NES) cathode chemistry can work inside electric vehicle battery packs.

The arrangement, announced October 13, 2026, marks the first time an OEM has co-funded an evaluation of cells that combine Gelion’s NES cathode with a graphite anode. Under the programme, the automaker will contribute engineering personnel, access to battery testing facilities and a portion of the funding, while Gelion performs parallel testing so both sides can cross-check results. Neither the identity of the partner, the financial value of the deal nor a completion timeline was made public.

The pact arrives just one week after Gelion disclosed a separate testing agreement with an automaker in the global top fifteen, a pairing that suggests several large manufacturers are casting a wider net across next-generation battery chemistries. Gelion already collaborates with Nissan in the United Kingdom on solid-state cell development, giving it an established foothold with established automakers.

At the heart of the company’s pitch is the claim that NES works as a drop-in cathode for production lines already turning out conventional lithium-ion cells. That compatibility angle matters commercially: it would allow manufacturers to adopt the material using standard anodes and electrolytes rather than rebuilding factories around an entirely new cell architecture. Gelion also frames sulfur as an abundant and domestically sourceable input that can deliver strong performance across a broad temperature range.

“This agreement with a top 5 global automotive manufacturer marks a major milestone in the validation of our NES™ cathode material,” said Matt Wood, chief executive of Gelion. He added that pairing the company’s materials know-how with the partner’s engineering capability and test infrastructure offers a strong chance to demonstrate both performance and manufacturability for demanding automotive use.

Sulfur has long attracted battery researchers because it is cheap and plentiful, but it has historically suffered from cycle-life and stability problems that limited its practical use in vehicles. Encapsulation at the nanoscale is one route the industry is exploring to address those weaknesses. If Gelion’s material proves viable in an automaker’s own labs, the company could move from promising supplier to genuine contender in the race to cut EV battery costs.
