Transformational Full Collaboration Agreement with a Tier One Battery Manufacturer

Successful Transition of the Materials Testing Agreement to a Full Collaboration Agreement

Gelion plc (AIM: GELN), the global energy storage innovator, is pleased to announce that the Materials Testing Agreement signed with a Tier-One battery manufacturer ("Partner") in April 2025 has now transitioned to a multi-year Collaboration Agreement. This milestone follows the successful and independent validation of Gelion's advanced Cathode Active Material (CAM) developed in partnership with the Max Planck Institute of Colloids and Interfaces (MPI) by the Partner.

The Partner is a global electronics and battery manufacturer with over 100,000 employees globally, operates major manufacturing facilities across Asia, Europe, and the Americas, serving industries such as automotive, industrial, and consumer technology.

This Collaboration Agreement marks a significant inflection point for Gelion, demonstrating clear industry recognition of Gelion's innovative sulfur battery platform by a world-leading manufacturer. Key features of the agreement include:

·      Joint development of pouch cell prototypes using Gelion-supplied CAM, targeting advanced lithium-sulfur battery applications.

·      Gelion scaling up CAM production to support prototyping efforts across the Partner's manufacturing sites.

·      Robust provisions protecting Gelion's intellectual property and confidentiality, safeguarding the Company's proprietary advancements.  

This partnership will facilitate acceleration of Gelion's pathway from prototype to commercialisation, enabling the Company to work alongside a Tier-One manufacturer and significantly derisking the development of industry-standard cells capable of high-power output and long-cycle life. The agreement supports Gelion's strategic focus on bringing its sulfur battery platform to commercial readiness, with potential applications across next-generation mobility, aviation, and energy storage solutions.

John Wood, CEO of Gelion, commented: "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 by collaborating with a partner with the market reach and experience with the complementary technologies and manufacturing capabilities needed to develop and deliver compelling full cell propositions while allowing Gelion to stay capital light ."

About Gelion

Gelion ("gel: ion") is a global energy storage innovator, supporting the transition to a more sustainable economy by commercialising globally important next generation battery technologies: Sulfur based, Lithium-Sulfur (Li-S), Sodium-Sulfur (Na-S) and Zinc-based (Zn) hybrid cells to electrify mobile and stationary applications and battery recycling technology.

Gelion plc (the Group) is listed on the London Stock Exchange's Alternative Investment Market and wholly owns UK based OXLiD Ltd and Battery Minerals Ltd and Australia based Gelion Technologies Pty Ltd.  Gelion is designing and delivering innovative battery technology to enable that transition and return value for its customers and investors.

In addition, Gelion is also delivering commercial Battery Energy Storage Systems (BESS) projects through its Integration Solutions business.

Sulfur Batteries

Gelion's effort is directed at the potential for sulfur-based cathode active materials (CAMs) to deliver low-cost & sustainable batteries with compelling performance. In the case of Li-S batteries, the target is a high-performance light-weight battery for the EV and e-aviation market. In the case of Na-S batteries, the target is an ultra-low-cost advancement on batteries currently employed in the stationary storage and economy EV market. The company's overarching goal is to help make global transport, energy consumption and storage more sustainable.

Glossary

Ah
Ampere hours. A measure of capacity stored in the cell. The larger the number the higher the capacity.
mAh/g(S)
The unit mAh/g(S) stands for milliampere-hours per gram of Sulfur (with S indicating "Sulfur"). It is a measure quantifying how many electrons (in mAh) can be stored per gram of Sulfur.
CAM
Cathode active material
Energy density (Wh/kg)
The ratio of energy stored per unit weight i.e. Watt-hours per kilogram. The higher the number the lighter the battery.
Pouch cell
An industry standard format of a battery which comprises a flat pouch-shaped design with a multi-layered laminate structure.
Cycle life
The number of full charge and discharge cycles a battery can complete before its capacity falls below a specified level, typically 80% of the original capacity. Higher cycle life indicates longer-lasting performance.
