Li-S Energy claims to boost energy density by 45% with new 20-layer lithium-sulfur battery

Li-S Energy has revealed its first 20-layer battery cells using its third-generation semi-solid-state lithium-sulfur (GEN3 Li-S) technology.

GEN3 Li-S 20-layer battery cells use a patented low-flammability electrolyte Li-nanomesh technology and Boron Nitride Nanotubes (BNNTs) to prevent dendrite formation. Compared to the company’s second-generation lithium-sulfur cells, the new cells offer greater energy density and more safety, due to a lower-porosity cathode material, optimized cathode material composition and low-flammability electrolyte. 

GEN3 cells currently demonstrate specific energy of 400 Wh/kg and energy density of 540 Wh/l. Li-S Energy says this is roughly double the energy density of Li-ion cells.

“Based on inquiries to date we anticipate this will be of significant commercial interest to high-value partners in sectors such as drones and eAviation,” the company said. “In addition to the GEN3 semi-solid-state Li-S cells, we continue to progress our R&D on full solid-state electrolytes in a co-funded project within the ARC Research Hub for Safe and Reliable Energy at Deakin, where we jointly aim to create a full-solid-state Li-S battery.”
