Battery technology company Li-S Energy has announced that its GEN3 semi-solid-state lithium sulfur (Li-S) battery cells have successfully passed a rigorous series of nail penetration tests with the results exceeding both the civilian and US military performance standards.
A total of 28 cells were tested, with the cells exceeding the nail penetration test requirements of the civilian UL2271 and UL2580 standards and the United States Military Performance Specifications MIL-PRF-32383/4X requested by the company’s aerospace partners.
"The ability to safely and reliably operate and transport drone technology is heavily reliant on battery stability," said Mark Xavier, CEO of V-TOL Aerospace, an Li-S Energy technology partner, who noted that the results will have a major impact on the civilian and military drone industry.
"The Li-S Energy GEN3 cell nail penetration test results indicate a far better risk profile than current battery technology which I believe will save lives and improve operational performance. We are looking forward to trialling the GEN3 cells in the coming months as part of our collaboration program with Li-S."
Li-S Energy is currently completing a $10 million three production line for the technology in Geelong, Victoria which will be able to complete hundreds of cells a month.
In the coming months Li-S Energy intends to conduct a suite of safety tests including crush, external short circuit, drop, vibration, high altitude, thermal (hot/cold range), plus extensive cycle testing to meet specific partner requirements and to finalise cell performance data sheets.
