Gelion reports sulfur battery breakthrough, inks MTA with top manufacturer

LONDON - Gelion plc (AIM:GELN), a global innovator in energy storage, has announced a significant breakthrough in sulfur battery technology, demonstrating promising high power and cycling capabilities. The advancements could potentially disrupt markets for drones, transportation, and energy storage systems. The company, building on its collaboration with the Max Planck Institute of Colloids and Interfaces (MPI), has successfully integrated MPI’s technology into sodium-sulfur coin cells, which are a standard battery testing platform.

The initial testing phase yielded impressive results, including superior power capability, with coin cells demonstrating robust capacity retention at rapid six-minute charge and discharge cycles. Additionally, the tests indicated outstanding longevity, with the batteries supporting over 1,000 charge and discharge cycles while retaining industry-standard capacity.

These advancements are particularly noteworthy as sulfur batteries have historically faced challenges regarding short cycle life and low power output, limiting their commercial viability. However, Gelion’s results suggest a potential shift, offering solutions that meet the high-power demands of electric vehicles and the rapid acceleration required by drones.

In a strategic move to foster commercialization, Gelion has entered into a Materials Testing Agreement (MTA) with a tier-one battery manufacturer. This partnership will allow the manufacturer to test and validate Gelion’s materials while ensuring the protection of intellectual property and confidentiality. The company expects to execute the agreement shortly, with more details to be announced in due course.

Gelion’s CEO, John Wood, expressed optimism about the company’s progress and the rapid engagement with significant global industrial players. The MTA is seen as a critical step toward the large-scale adoption of Gelion’s sulfur battery solutions.

These developments are based on a press release statement and are part of the ongoing narrative of innovation within the energy storage sector. As the industry seeks sustainable and high-performance battery technologies, Gelion’s recent advancements position the company as a potential key player in the market’s evolution.
