GELION PLC
GELION PLC is a public limited company registered in England and Wales under company number 09796512, according to Companies House. Incorporated on 26 September 2015, the company is recorded with an “Active” status, with its registered office at C/O External Services Limited, Central House, 20 Central Avenue, St Andrews Business Park, Norwich, NR7 0HR.

GELION PLC is a battery technology developer spun out of the University of Sydney in 2015 by Professor Thomas Maschmeyer of the university’s School of Chemistry, which remains a shareholder in the company, according to a University of Sydney news release. The company develops next-generation energy-storage chemistries, including lithium-sulfur cells for electric vehicles, drones and electric aviation, sodium-based cells, and non-flow zinc-bromide gel batteries marketed under the Endure brand for off-grid and stationary renewable-energy storage in agriculture, mining and remote communities. GELION PLC has also developed a lithium-ion battery recycling process aimed at recovering lithium and other materials from spent cells and manufacturing waste, according to the company’s own reporting.
GELION PLC’s ordinary shares have been admitted to trading on AIM, the London Stock Exchange’s market for smaller growth companies, under the ticker GELN since 1 December 2021, when the company listed at an initial market capitalisation of £154 million, according to the University of Sydney. For the six months ended 31 December 2025, the company reported total income of £0.5 million, up from £0.4 million a year earlier, and a pre-tax loss narrowed to £3.3 million from £3.6 million, with cash and cash equivalents of £10.5 million, according to unaudited half-year results announced on 2 March 2026.
On 21 October 2025, GELION PLC and TDK Corporation announced a full collaboration agreement to develop battery technologies using GELION PLC’s sulfur cathode active material, with prototyping planned at TDK’s plant in Nagano, Japan. On 30 June 2026, Matthew Forster Wood was appointed Chief Executive Officer and director, succeeding John William Wood, who stepped down from the board the same day, according to company announcements.

Shareholders
Shareholders of GELION PLC
Companies House’s persons-with-significant-control register for GELION PLC (company number 09796512) currently records no active individual or corporate person with significant control. The company’s sole active filing on the register is a statement, dated 25 September 2016, that “there is no registrable person or registrable relevant legal entity in relation to the company,” according to Companies House. Since GELION PLC’s ordinary shares were admitted to trading on AIM on 1 December 2021, changes in shareholdings above the disclosure thresholds are announced separately through the Regulatory News Service as director dealings and notifications of major holdings, rather than recorded on the PSC register. The University of Sydney has stated that it holds a shareholding in GELION PLC as a result of the company’s 2015 spin-out from the university, though its current percentage interest was not independently verified against a primary filing in this review.
Data availability
Classification: Partial. Companies House confirms that no individual or entity currently meets the UK’s threshold for registration as a person with significant control of GELION PLC, but a complete, independently verified breakdown of the company’s major AIM shareholders was not compiled from a primary regulatory filing in this review.
