Gelion and tier-one battery maker sign multi-year collaboration deal

LONDON - Gelion plc (AIM:GELN) has transitioned its materials testing agreement with an unnamed tier-one battery manufacturer into a multi-year collaboration agreement, the energy storage company announced Thursday.

The partnership follows successful independent validation of Gelion’s advanced Cathode Active Material (CAM) for sulfur batteries, which was developed with the Max Planck Institute of Colloids and Interfaces.

According to the company statement, the unnamed partner is a global electronics and battery manufacturer with over 100,000 employees and manufacturing facilities across Asia, Europe, and the Americas.

Under the agreement, the companies will jointly develop pouch cell prototypes using Gelion’s CAM technology, targeting lithium-sulfur battery applications. Gelion will scale up CAM production to support prototyping efforts across the partner’s manufacturing sites.

The collaboration includes provisions to protect Gelion’s intellectual property and confidentiality, the company said.

John Wood, CEO of Gelion, stated: "We see enormous scope for our Sulfur Cathode material to have broad reach and impact across the full field of battery applications. This agreement allows us to move quickly to realise its full potential."

The partnership aims to accelerate Gelion’s pathway from prototype to commercialization while allowing the company to maintain a capital-light approach. Potential applications include next-generation mobility, aviation, and energy storage solutions.

The agreement follows the initial materials testing agreement signed in April 2025.

Gelion, listed on London’s AIM market, develops sulfur-based battery technologies including Lithium-Sulfur, Sodium-Sulfur, and Zinc-based hybrid cells for mobile and stationary applications.
