About
Gelion plc is developing next-generation sulfur-based battery technologies designed to accelerate the global clean energy transition through sustainable, high-performance and cost-effective energy storage solutions. Central to the company’s strategy is its proprietary Nano-Encapsulated Sulfur (NES™) cathode active material technology, which uses nanoconfinement to control sulfur behaviour in lithium-sulfur and room-temperature sodium-sulfur battery architectures. NES™ is being developed to overcome historical sulfur battery limitations while targeting high energy density, strong power capability and compatibility with existing battery manufacturing infrastructure, enabling scalable “drop-in” production within established gigafactories. With target applications spanning electric mobility, e-aviation, grid and stationary storage, Gelion works with Tier One industrial, academic and government partners around the world to commercialise its NES™ platform.
