Sion Power reports 400 Wh/kg, 700 Wh/L and 350 cycles under 1C for Li-ion battery with Li-metal anode technology
Sion Power reported that a Licerion-Ion system has achieved 400 Wh/kg, 700 Wh/L and 350 cycles under 1C discharge conditions. Dr. Yuriy Mikhaylik, Sion Power’s Director of Materials, is presenting details on this performance in an invited presentation at the ECS meeting in Honolulu this week.
Licerion, a product of Sion Power’s technical collaboration with BASF (earlier post), is a comprehensive battery system that significantly enhances the energy and cycle life of rechargeable batteries using a physically protected metallic lithium anode. The physical protection is based on ceramic-polymer composite membranes and is combined with specialized cell design and electrolyte systems providing smooth, dendrite-free lithium deposition and chemical protection of the exposed metallic lithium surface. This approach addresses the safety and cycle life problems that have historically plagued lithium-metal electrodes.
Sion combines its protected lithium anodes with intercalated metal oxide cathodes typically used for Li-ion batteries (Licerion-Ion) and with advanced sulfur cathodes (Licerion-Sulfur).
Sion, in collaboration with BASF, is targeting 500 Wh/kg, 1000 Wh/L and 1000 cycles.

Sion Power’s Licerion-Sulfur products are being commercialized via its partnership with Airbus Defence and Space. (Earlier post.) An earlier version of the technology was employed in setting a world record for the longest duration unrefueled flight for a high altitude pseudo-satellite (HAPS).

Sion Power is in the process of expanding its facilities in Tucson, Ariz. for the production of prototype large format Licerion Ion cells. These cells will be available by December 2017. In the interim, Sion Power is evaluating potential volume manufacturing partners to supplement in-house capacities.
