Issue of Q3 2026 Newsletter

Q3 2026 Newsletter

Gelion is seeking to replace the critical minerals in current Lithium-ion battery cathode materials with the Company’s Nano-Encapsulated Sulfur (NES™), a material that is low cost and designed to drop-in to existing global manufacturing lines. Gelion’s NES™ is made from sulfur, which is abundant, mining-free, and free from supply chain constraints.

Gelion (LSE: GELN), the sulfur battery technology company, is pleased to publish its Q3 2026 newsletter, marking a period of strong progress for Gelion, with new global automotive collaborations, continued independent validation of NES™ with partners including QinetiQ and National Laboratory of the Rockies (NLR), and the publication of the 2026 Annual Report, reinforcing the Company’s partnership-led path to commercialisation.

ARENA ACPC Program: Project activities remain on track to support the scale-up of CAM production to meet future volume needs, with work underway to prepare for the next project milestone in Q4 2026.

Max Planck Institute of Colloids and Interfaces (MPI): Ongoing collaborative technology development, optimisation activities and knowledge exchange, with two patent applications recently filed based on Gelion's work with MPI.

Mitsui Kinzoku: The first shipment of materials has been delivered, demonstrating programme kick-off and progress against the goals set out in the agreement.

National Laboratory of the Rockies (NLR): Materials for Phase 1 of the project have been successfully shipped in line with agreement milestones, with preliminary results validating NES™ performance and reproducibility.

QinetiQ: Next collaboration is discussion following successful completion of ARMD4 drone mission demonstrator.

TDK Corporation: Third shipment of materials delivered to support continued testing and evaluation activities in line with agreement milestones.

Gelion entered into a Material Transfer Agreement with a top 15 global automotive OEM to assess the applicability of its NES™ cathode platform across a range of future electric vehicle battery technologies.

Gelion entered into a Proof of Concept Agreement with a top five global automotive OEM to evaluate its proprietary NES™ cathode active material for electric vehicle battery applications.
