Gelion plc is pioneering next-generation battery technologies for clean energy storage solutions. Established in 2015 from the University of Sydney, the company specializes in two key battery types: lithium-sulfur and zinc-bromide. Currently listed on the AIM market of the London Stock Exchange, Gelion’s integrated energy storage systems emphasize reliability, cost-effectiveness, and environmental sustainability. With projections indicating a demand for 180 times more battery production by 2030 to support renewable energy adoption, the company’s innovations are essential in meeting this challenge.

Battery Technology

Gelion’s technological focus is on two distinct battery chemistries. Their lithium-sulfur (Li-S) technology represents a significant improvement over conventional lithium-ion batteries, offering enhanced energy density and safety features. Notable achievements include the fabrication of a 395 Wh/kg lithium-sulfur 9.5 Ah pouch cell and achieving 402 Wh/kg energy density with their GEN3 semi-solid-state Li-S cell.

The zinc-bromide battery technology features a non-flow gel design that is ideal for stationary energy storage applications. These batteries operate without costly cooling systems and can completely discharge without sustaining damage. They perform exceptionally well in extreme environments and remote locations, showcasing reliable operation across varied temperature ranges.

Furthermore, through its subsidiary OXLiD, Gelion has developed an ultra-thin, flexible solid electrolyte system aimed at high-energy, long-cycle batteries for aerospace and automotive uses. This advancement underscores the company’s commitment to pushing the boundaries of battery technology.

Recent Projects

In late 2024, Gelion received a £2.5 million (A$4.8 million) grant from ARENA to launch the Advanced Commercial Prototyping Centre Project in Sydney. This facility aims to enhance the production of Gen 3 Lithium Sulfur and Silicon Sulfur battery technologies. Additionally, the company commenced its energy storage solutions business, achieving its first commercial order. Moreover, Gelion established Battery Minerals Ltd, a UK subsidiary focusing on Li-Ion recycling, supported by a £170,000 grant from DBT.

Investors

Gelion’s investor landscape features key shareholders, including Perinato Pty Ltd (Maschmeyer Family Trust) with a 12.7% stake, Janus Henderson Investors holding 6.8%, and Adrien Amigues with 6.28%. The company has successfully concluded multiple funding rounds, including a £4.0 million capital raise in 2023 and a £1.7 million raise in 2024. Strategic collaborations with entities like Glencore and Ionblox further bolster Gelion’s technological capabilities.
