Gelion develops high-energy-density lithium-sulfur cell

Australian battery manufacturer Gelion has fabricated a 395 Wh/kg lithium-sulfur 9.5 Ah pouch cell.

Gelion had previously produced 1.0 Ah cells using the OXIS Gen2 cell technology it acquired from Johnson Matthey, providing specific energy of 245 Wh/kg. Reaching 395 Wh/kg aligns with independent modelling projections for the energy density of a larger cell format, the company said. Gelion aims to supply sulfur batteries for a wide range of applications including mass-market EVs, electric vertical-takeoff-and-landing (eVTOL) aircraft, drones and stationary energy storage systems (ESS), as higher specific energy translates to lighter batteries.

“This result further validates Gelion’s Li-S technology plan,” said John Wood, CEO of Gelion. “Whilst these are still early results, we intend to build on them actively throughout 2024, demonstrating the core proposition that Gelion is assembling.”
