Lithium-Metal Rechargeable Batteries Meet EV Performance Needs

February 19, 2020 by Paul Shepard

Sion Power® announced the demonstration of its Licerion EV™ technology. Licerion EV is specifically designed for electric vehicle applications, focusing on high energy density, increased cycle life, and fast charging capability.

Through optimization of its protected lithium anode (PLA) and advanced electrolyte formulations, Sion Power performed tests on 1.8 Ah cells, which resulted in 800 full depth of discharge cycles to 70% capacity. Sion Power projects Licerion EV will have 420 Wh/kg and 700 Wh/L when scaled to commercial design. Charge times of 15 minutes to 100% state of charge were repeatedly demonstrated with 99.7% efficiency.

"This achievement demonstrates a remarkable balance between high energy density, faster charge times, and longer cycle life," says Dr. Urs Schoop, Chief Technical Officer at Sion Power. Dr. Schoop goes on to say that, "Though battery experts know fast charging is not ideal for battery longevity, the market demands this as an option. Sion Power has the technology to produce a viable alternative to traditional lithium-ion cells for many applications, including EV."
