Sion Power’s experimental lithium metal cells deliver 2,500 cycles

Sion Power says one of its multilayer lithium metal pouch cells has performed for over 2,500 cycles, retaining 70% of its initial capacity.

The cell was charged for 180 minutes at the C/3 rate and completely discharged in 45 minutes at the 4C/3 rate.

The experimental cell is part of Sion Power’s Licerion product line. Licerion batteries have lithium metal anodes and are compatible with LFP and NMC cathodes. The company says its 6 Ah Licerion cell can be fast-charged to 80% capacity in less than 15 minutes. An independent test lab validated its achievement of 800 cycles at the C/3 rate and the 4C/3 rate. Also, the firm says a 17 Ah version was independently verified to reach an actual specific energy of 400 Wh/kg and an energy density of 780 Wh/l.

“This excellent R&D achievement demonstrates the headroom of our technology when it comes to developing products for commercial trucking and automotive applications,” said Sion Power CEO Tracy Kelley.
