Notes to Editors

About Gelion

Gelion ("gel: ion") is a global -energy storage innovator, supporting the transition to a more sustainable economy by commercialising two globally important next generation technologies: Lithium-Sulfur (LiS) and Zinc-based (Zn) hybrid cells to electrify mobile and stationary applications. Gelion plc (the Group) is listed on the London Stock Exchange's Alternative Investment Market and wholly owns 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.

Lithium Sulfur

Gelion's effort is directed at the potential for the LiS chemistry to deliver double the gravimetric energy density of standard Lithium-ion chemistries whilst at the same time reducing cost and increasing safety targeting the EV and e-aviation market, helping to make global transport, energy consumption and storage more sustainable.

Gelion is developing a product for its high energy density sulfur cathode at its expanded R&D facilities in Sydney, enabling it to integrate with a variety of anodes ranging from graphite to silicon to lithium metal, depending on the targeted application.

Gelion recently also expanded in the UK¹ by acquiring OXLiD Ltd, significantly increasing Gelion's capability in cathode improvement thereby accelerating path to commercial partners and commercialisation.

Zinc

Gelion is adapting its zinc technology to comprise an alternate cathode technology, a zinc hybrid cell to develop complementary next-generation batteries for the lead-acid eco-system. Early testing indicates that this solution has the potential to maintain good energy density levels with enhanced cost and safety aspects. Once fully developed, Gelion intends for our zinc technology to provide a durable and sustainable market extension within the ecosystem that supports lead-acid batteries.
