Street Calls of the Week
LONDON - Battery technology company Gelion plc (AIM:GELN) announced Thursday that its Sulfur Cathode Active Material (CAM) has been successfully integrated into coin cells using standard lithium-ion and sodium-ion battery components, demonstrating its potential as a drop-in solution for existing manufacturing infrastructure.
The company reported that its sulfur-based cathode material functions with conventional electrolyte systems based on carbonate solvents and hexafluorophosphate salts, which are widely used in gigawatt-scale battery production. This compatibility addresses a significant technical barrier, as traditional sulfur cathodes typically cannot be used with these standard electrolyte systems due to chemical incompatibilities.
According to the announcement, Gelion has tested its Sulfur CAM in both lithium-ion and sodium-ion cell architectures using industry-standard components including polyolefin separators and graphite or hard carbon anodes.
"These results reflect Gelion’s commitment to accelerating our battery technologies toward the broad market," said John Wood, CEO of Gelion, in the press release statement.
The development builds on the company’s previous announcement in September 2025 regarding the successful transfer of technology from the Max Planck Institute of Colloids and Interfaces and scale-up of the cathode material.
Gelion stated that this advancement could allow its technology to be integrated with established materials supply chains and manufacturing processes used in current battery production for electric vehicles, energy storage systems, and personal devices.
The company indicated it will continue refining its Sulfur CAM for specific applications with lithium-ion and sodium-ion battery components, while also working toward cathodes with industrially relevant areal capacity and prototype cell development.
