Three Li-S Patents Advance Successfully in U.S.

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".
