Li-S Energy Ltd (ASX:LIS) has seen its share price rise 25% on news it has substantially improved the performance of its lithium-sulfur battery technology, achieving almost 500 watt hours (Wh) per kilogram as indicative of lithium-sulfur cell performance.
The company has manufactured full-size 10Ah semi-solid-state cells which deliver an energy density of 498Wh/kg on first discharge from its Phase 3 automated pouch cell production facility.
After formation cycling, the performance rose to 456Wh/kg – an industry leading figure – with the cells continuing to cycle in ongoing testing.
The market responded strongly, and by 14:31 AEDT, shares in LIS were trading at 17 cents – a rise of 41.67% since the market opened.
The crucial nature of this news lies in the fact higher energy density – yielded by these improvements – results in a lighter battery. LIS’ focus on the growing market of drones, defence, and electric aviation means weight is an important factor.
Potential range, payload, and operating time are set to improve based on this data.
CEO of LIS partner V-TOL Aerospace Mark Xavier said the development would be significant for the drone and aerospace industries.
“V-TOL would like to congratulate LIS on this significant milestone achievement that has
exceeded our expectations and initial requirements for our joint development of the Pegasus uncrewed air system,” he said.
“We anticipate cell performance at this level will generate substantial global interest and
opportunity for LIS across the drone, aerospace and defence sectors.“
