Sion Power’s Licerion battery tech reaches more than 2500 cycles

Sion Power has reached a development milestone with its Licerion Electric Vehicle (EV) technology, demonstrating more than 2500 cycles to 70% of their initial capacity.

The company said that the results were achieved by multi-layered pouch cell prototypes. During the demonstration, the battery was charged in 180 minutes (C/3 rate) and completely discharged in 45 minutes (4C/3 rate) 2,500 times before it dropped below the minimum original capacity that is considered acceptable for electric cars.

C is generally the capacity divided by 1 hour; this means a fully charged battery with a capacity of 10Ah should be able to provide 10 Amps for one hour. The Licerion cells may not be able to stand fast charging like solid-state batteries and robust like many other cells, but what makes them impressive are their technical specifications.

The Location is a versatile hybrid lithium-metal cell technology that utilizes several levels of lithium protection and can be paired with common cathode materials. The current 6 Ah large-format Licerion EV cell can be fast-charged to 80% capacity in less than 15 minutes. It has exceeded 800 cycles as validated by an independent test laboratory under the identical conditions of C/3 4C/3. The Location-EV with 17 Ah cell has been independently verified with actual specific energy of 400 Wh/kg and energy density of 780 Wh/L.

“Finding a practical balance between specific energy, energy density, and cycle life is a large part of battery development,” says Tracy Kelley, CEO of Sion Power. Mr. Kelley goes on to say. “This excellent R&D achievement demonstrates the headroom of our technology when it comes to developing products for commercial trucking and automotive applications.”
