Gelion PLC - London-based battery energy storage systems firm - Achieves major technical milestone in the development of its next-generation sulfur battery technology, calling it "a major step" towards delivering high-energy-density, low-cost sulfur-based batteries for e-aviation, electric mobility, stationary storage and other commercial applications. Specifically, Gelion says its proprietary cathode active material crosses the 4Q threshold, demonstrating stable cycling with the industry-recognised 4Q areal capacity in coin cells, the industry-standard platform for evaluating new battery materials. This follows the successful technology transfer from the Max Planck Institute of Colloids and Interfaces and the Gelion CAM scale-up announced in September. Gelion says the achievement directly supports its energy-density and cost objectives for next-generation sulfur-based batteries. Read More
