Renowned Scientist Prof. Markus Antonietti Appointed as Technology Advisor

Gelion (AIM: GELN), the global energy storage innovator, is pleased to announce the appointment of Professor Dr. Dr. h.c. Markus Antonietti as Technology Advisor, effective immediately. He will provide strategic guidance on battery technology development, primarily supporting the recently announced collaboration with the Max Planck Institute (MPI) on pioneering sulfur battery innovations.

Professor Antonietti is one of the world's most influential scientists, currently ranked as the fourth best chemical scientist globally and first in Germany[1]. He is the Founding Director of the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, and his groundbreaking research spans sustainable chemistry, catalysis, electrocatalysis, artificial photosynthesis, carbon sequestration, and soil remediation. Throughout his distinguished career, he has received numerous prestigious awards, including the Goldschmidt-Elhuyar Award (2003), the Grignard-Wittig Award (2011), the Liebig Medal (2016), and the Order of Merit of the Federal Republic of Germany (2018). In 2024, he was honoured with the prestigious Solvay Chair in Chemistry.

Professor Antonietti's appointment marks a significant milestone for Gelion, bringing invaluable expertise and aligning with the Company's vision to advance cutting-edge battery technologies. To recognise his contribution, he will receive 1.5 million nominal cost options over Gelion's ordinary shares of 0.1p each, vesting equally over three years with the exercise period being five years from the Commencement Date. Any IP generated under this advisory contract will vest with Gelion.

Prof. Thomas Maschmeyer, Founder and Director of Gelion, commented: "I am delighted that Gelion has been able to attract such an outstanding and internationally sought-after individual as Prof. Antonietti into a technology advisory role. His involvement is a strong endorsement of our journey and a validation of our mission to push the boundaries of energy storage innovation."

John Wood, CEO of Gelion, added: "Prof. Antonietti quite simply sees and understands physical systems in a manner that surpasses the ordinary. His MPI team echoes this in terms of their drive and capability. Our founder Professor Maschmeyer similarly displays, attracts and harnesses creativity, especially that required to take science to the next level into scale and application. One starts the sentence with pure chemistry and the other continues it with the process for realization."

Prof. Dr. Markus Antonietti commented: "Joining Gelion as a Technology Advisor is an exciting opportunity to translate innovative chemistry into practical solutions. Gelion's vision for advanced sulfur battery technology aligns perfectly with my research focus, and I am eager to contribute to their mission of creating sustainable, high-performance energy storage solutions."
