US-based lithium sulfur battery producing company Lyten consistently surpasses 90% yield from its automated battery production line, confirming the manufacturing capability of its lithium sulfur battery utilizing a sulfur cathode and lithium metal anode, the company announced Tuesday.
Lyten's pilot facility proved the company's ability to rapidly scale up production of lithium-sulfur batteries by converting existing lithium-ion gigafactories to lithium-sulfur production within a six-week period that cost less than 2% of the total capital output.
'Lyten now has demonstrated that lithium-sulfur can be built in standard cylindrical and pouch formats, can be scaled to automated manufacturing, and can be done on the same equipment and processes already being used around the globe to manufacture legacy lithium-ion,' Dan Cook, Lyten CEO and co-founder, was quoted as saying in the statement.
'The result is a significant reduction in the manufacturing scale-up risk for a locally sourced and locally manufactured battery that can leapfrog the performance and cost of existing lithium-ion and future solid-state batteries,' he added.
Lyten argued that its lithium-sulfur battery chemistry utilizes no NMP (N-methyl-2-pyrrolidone) in the cathode manufacturing process, eliminating the potential health, safety and environmental impacts of the highly toxic solvents that are standard in the current lithium-ion batteries.
The company also announced that the lithium-sulfur battery cell is proven to be highly tolerant of metallic contamination, significantly reducing the capital equipment and operational costs associated with preventing metal contamination in today's leading battery chemistries.
'To achieve mass market adoption, lithium-sulfur must be able to be manufactured at enormous scale and at a price immediately on par with or better than today's already scaled-up lithium-ion batteries,' said Celina Mikolajczak, chief battery technology officer at Lyten.
'The complete elimination of NMP and its ability to tolerate metallic contamination and defects creates a cell that is highly manufacturable. Lower-cost production that is better for the environment is a win every way you look at it,' Mikolajczak said.
