Lithium-Sulfur Cell High Energy Density Milestone Achieved
Gelion (AIM: GELN), el innovador angloaustraliano en baterías, anuncia una actualización sobre el desarrollo de su batería de litio-azufre (Li-S) de próxima generación.
Gelion has achieved a high energy density milestone by fabricating a 395 Wh/kg lithium-sulfur 9.5 Ah pouch cell (commercial cell format). This result represents a c. 60% increase in the energy density (lower weight) compared with current lithium-ion batteries (approximately 250 Wh/kg).
Further to the announcement on 19 March 2024, Gelion had produced 1.0 Ah cells using the OXIS Gen2 cell technology that achieved energy density of 245 Wh/kg. The achievement of 395 Wh/kg aligns with the independent energy density modelling projections for a larger cell format.
Achievement of this milestone represents a key technology proof point for Gelion. By re-establishing this performance, building on the OXIS Gen 2 technology and IP acquired from Johnson Matthey. The Company has set a new benchmark against which to compare upcoming 'Next Generation' cell which targets further performance improvements upon this announced result.
On 19 March 2024, Gelion identified that testing of our Next Generation cell technology is exhibiting our expected solid-to-solid conversion (see Glossary) comportamiento toward enhanced stability and longevity. We will continue to progress these developments in addition to the silicon-sulfur cell technology in cooperation with Ionblox.
Gelion's ambition for its next generation platform is to unlock the potential of sulfur batteries for a wide range of global applications including electric vertical-takeoff-and-landing (eVTOL) aircraft, drones, electric vehicles (EV), and stationary energy storage (ESS), as high Wh/kg translates to lighter batteries and opens many advantages for these markets. Sulfur being an abundant material offers a future not limited by geographically concentrated and controlled battery metals which significantly improves battery lifecycle sustainability.
John Wood, director ejecutivo de Gelion, dijo: "This result further validates Gelion's Li-S technology plan. In 2023 we established a leading Li-S cell technology foundation following the acquisition of OXLiD and the IP acquired from OXIS and Johnson Matthey. Whilst these are still early results, we intend to build on them actively throughout 2024, unveiling and demonstrating the unique core proposition that Gelion is assembling.
"We continue to build on our position within the global battery industry and focus on establishing a strong identity and market presence which is centred on the key metrics of performance, cost, and safety, ready to leverage once our technologies go-to-market."
Antecedentes
In May 2023, Gelion updated on the progress made using the battery technology package acquired from Johnson Matthey (containing, in addition to its own IP, the Li-S IP and know-how from OXIS Energy). Gelion has worked over the past nine months to benchmark, improve on, and define a next generation approach to Li-S battery development.
Li-S batteries are an advanced alternative to Li-ion batteries that can achieve much greater gravimetric energy densities (measured as amount of energy per battery weight). This is critical to drive down the weight in mobile applications such as EV's, e-aviation, and drones, reducing auxiliary component cost and lessening their upfront environmental impact. They do not contain rare metals in the cathode and can be scaled to meet the demands of global electrification. The technology shows promise to be safer (lower risk of fires) than current batteries.

Glosario
Ah | Ampere hours. A measure of capacity stored in the cell. The larger the number the higher the capacity. |
Densidad de energía (Wh/kg) | The ratio of energy stored per unit weight i.e. Watt-hours per kilogram. The higher the number the lighter the battery. |
Pouch cell | An industry standard format of a battery which comprises a flat pouch-shaped design with a multi-layered laminate structure. |
Solid-to-solid conversion | A low or polysulfide-free conversion of sulfur within the cathode. Polysulfides are a liquid form of sulfur that are corrosive and reduce cycle life in traditional lithium-sulfur batteries. Solid-to-solid conversion helps mitigate the formation of the polysulfides. |
Acerca de Gelión
Gelion ("gel: ion") es un innovador mundial en almacenamiento de energía que apoya la transición hacia una economía más sostenible mediante la comercialización de dos tecnologías de próxima generación de importancia mundial: celdas híbridas de litio-azufre (Li-S) y zinc (Zn). para electrificar aplicaciones móviles y estacionarias. Gelion plc (el Grupo) cotiza en la bolsa El mercado AIM de la Bolsa de Valores de Londres y es propietaria total de Gelion Technologies Pty Ltd, con sede en Australia. Gelion es diseñando y entregando tecnología de baterías innovadora para permitir esa transición y generar valor para sus clientes e inversores.
azufre de litio
Gelion's effort is directed at the potential for the Li-S chemistry to deliver double the gravimetric energy density of standard Lithium-ion chemistries whilst concurrently reducing cost and increasing safety, targeting the EV and e-aviation markets, helping to make global transport, energy consumption and storage more sustainable.
Gelion está desarrollando un producto para su cátodo de azufre de alta densidad energética en sus instalaciones ampliadas de I+D en Sydney, lo que le permite integrarse con una variedad de ánodos que van desde grafito hasta silicio y litio metálico, según la aplicación específica.
Gelion también se expandió recientemente en el Reino Unido al adquirir OXLiD Ltd, aumentando significativamente su capacidad en la mejora de cátodos, acelerando así el camino hacia socios comerciales y la comercialización.
Zinc
Gelion está adaptando su tecnología de zinc para incluir una tecnología de cátodo alternativo, una celda híbrida de zinc para desarrollar baterías complementarias de próxima generación para el ecosistema de plomo-ácido. Las primeras pruebas indican que esta solución tiene el potencial de mantener buenos niveles de densidad de energía con mayores aspectos de costo y seguridad. Una vez completamente desarrollada, Gelion pretende que su tecnología de zinc proporcione una extensión de mercado duradera y sostenible dentro del ecosistema que sustenta las baterías de plomo-ácido.
