Sion Power to ramp production of lithium metal battery
US battery techology developer Sion Power is starting to ramp up production of a lithium metal battery.

The large format lithium metal-based battery, developed with BASF of Germany, will offer 500 Wh/kg, 1,000 Wh/L and 450 cycles. This compares to around 100 Wh/kg for lithium ion cells used in electric cars.

The company is buying production equipment and recruiting staff for its plant in Tucson, Arizona, says Tracy Kelley, Chief Executive Officer of Sion Power. “Sion Power is supplementing our outstanding core team with talented scientists and engineers from a variety of fields to support our efforts toward production readiness,” se said. “When this step toward commercialization is complete, we will be well equipped and ready to produce a rechargeable battery unlike any on the market today.”

The company has more than 172 issued patents in the US and abroad, with152 pending for the technology. The rechargeable Licerion cells measure 10 cm x 10 cm x 1 cm and have a capacity of 20 Ah. At the core of Licerion technology is a protected metallic lithium thin film anode with multiple levels of physical and chemical protection to enhance the safety and life of lithium metal anodes. These anodes are paired with traditional lithium-ion intercalation cathodes.

The pilot equipment for the large format Licerion battery is currently being optimised for production at the  Tucson plant. When complete, batteries and battery packs will be available for a variety of applications from electric vehicles to unmanned vehicle systems as well as military and portable power packs. "We are on track to deliver product to a select group of partners by the end of 2018,” said Kelley.
