Battery maker Gelion claimed a high energy density milestone by making a 395Wh/kg lithium-sulphur 9.5Ah pouch cell with 60% higher energy density than current lithium-ion batteries.
The Australian company said this aligns with the independent energy density modelling projections for a larger cell format. The company is aiming to make sulphur batteries for a wide range of applications, including EVs, electric vertical-takeoff-and-landing aircraft, drones and energy storage. A high Wh/kg translates to lighter batteries and many advantages for these markets, it said.
John Wood, CEO of Gelion said: “This result further validates Gelion’s lithium-sulphur technology plan. In 2023 we established a leading lithium-sulphur 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.”
