Pouch cells using Sion Power Corporation’s lithium-metal anode technology have demonstrated more than 2,500 cycles to 70% of initial capacity.
The results for the firm’s Licerion technology were achieved by a multilayer R&D pouch cell, charged in 180 minutes (C/3 rate), and completely discharged (100% depth of discharge) in 45 minutes (4C/3 rate).
Licerion is a hybrid lithium-metal cell technology that uses levels of lithium protection and can be paired with common cathode materials, including LFP and NMC.
Sion Power’s 6Ah large-format Licerion EV cell has exceeded 800 cycles, as validated by an unnamed independent test laboratory under the identical conditions of C/3, 4C/3.
The same 6Ah cell can be charged to 80% capacity in less than 15 minutes, say the firm.
The Licerion-EV, 17Ah cell, has been independently verified with an actual (not projected) specific energy of 400 Wh/kg and energy density of 780 Wh/L.
