RNS Number : 7244D  Gelion PLC  16 October 2025

16 October 2025

Gelion plc
("Gelion", the "Company" or the "Group")

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 ."

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.
