Sion Power to introduce new battery format


The US-based lithium-metal battery specialist Sion Power is introducing their ‘Licerion’ rechargeable battery for electric vehicles at the Battery Show North America in Novi, Michigan in September. The 17 Ah Licerion EVcell boasts over 400 Wh/kg and 810 Wh/L in a large-format pouch cell.

According to the manufacturer, the new cell format is particularly powerful, because “Sion Power is backing Licerion technology with decades of research and development in rechargeable lithium-metal battery technology”. As a result, the company has developed a full-scale cell that “meets the requirements of next-generation automotive targets”. Additionally, independent testing has already been undertaken on the new cells, with the result that 6 Ah Licerion-EV cells reached over 800 cycles, demonstrated fast charge capability (80% of charge in 15 minutes), excellent power capability, and safety, according to Sion.

“This is a watershed moment for Sion Power’s push toward next-generation electrified vehicles,” says Tracy Kelley, CEO of Sion Power. Mr. Kelley goes on to say, “I am extremely proud of what we have accomplished. Our Licerion-EV technology has demonstrated a blend of energy, safety, and electrical performance that is unmatched. We look forward to continued work with our partners to commercialize our revolutionary battery system.”

Sion Power first attracted our notice in 2016, when the startup was cooperating with BASF to develop battery cells with an energy density of 400 Wh/kg and 700 Wh/kg, as well as 350 charging cycles and in 2018, when the company made their production announcement.
