Gelion plc

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

 

Successful Advancement of Three Lithium-Sulfur Patents in the U.S.

 

Gelion plc (AIM: GELN), the global energy storage innovator, is pleased to
announce further strengthening of its Lithium-Sulfur (Li-S) intellectual
property portfolio, with the award of two patents and the acceptance of one
application by the United States Patent and Trademark Office (USPTO).

This development marks a positive development in Gelion's IP strategy,
reinforcing protection of its core Li-S technology. By securing patent
coverage in critical areas, Gelion continues to build a defensible moat around
its unique approach to next-generation sulfur technology.

Strengthening U.S. Patent Protection

Gelion has successfully advanced several patent applications pertaining to its
core Li-S technology this year including:

·     Two newly granted patents and one application allowed in the U.S.,
providing protection for different aspects of the Group's technology and
aligning directly with its roadmap.

·      These patents protect advancements that deliver:

o  enhancement of cycling performance and extension of cell lifespan -
resulting in longer usable life with cells able to be charged and discharged
more times without significant decline in energy outputs

o  one-step manufacturing of single or double-sided protective coatings on
alkali metal electrodes - reducing manufacturing complexity and costs, and
enabling improvements in safety and cycling stability

o  precision thermal and state-of-charge management of cells within a module
- preventing thermal runaway, enhances operational safety, and improves
efficiency.

Each of these advances strengthens Gelion's proprietary position and directly
supports real-world deployment of safer, high-performance Li-S batteries.

A Leading Global Li-S Portfolio

With this progress, Gelion's Li-S portfolio now comprises over 200 patents and
applications across 40 families, spanning anode, cathode, electrolyte, cell
engineering, manufacturing techniques, and battery management. This breadth of
coverage provides end-to-end protection across the Li-S value chain and
underpins the Company's strategy to commercialise safer, lighter, and
longer-lasting batteries.

John Wood, CEO of Gelion, commented: "Gelion's investment in innovation is
aimed at establishing a position of recognition in the global battery
marketplace.  IP registration and protection is an important factor in
achieving this.  Our pace of innovation is strong and in particular we have
strong momentum gaining new knowledge about how to deliver enhanced
performance from Sulfur technology".

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.
