Sodium Ion | Comparison Against Lithium Ion

Na-ion battery

Li-ion battery

Elemental Abundance

~23000 ppm

20 ppm

Gravimetric Energy density

140-150 Wh/Kg

140-280 Wh/Kg depending on chemistry (NMC, LFP, LTO, NCA etc.)

Volumetric Energy Density

250-400 Wh/L

250-750 Wh/L depending on chemistry (NMC, LFP, LTO, NCA etc.)

Cycle Life

Fast Charging Capability

Demonstrated @ 4C for short period of time; R&D still ongoing

Depends on chemistry (NMC - <1C, LFP - <2C, LTO - <6C)

Operating Temperature

–20oC to 60oC

0oC – 45oC (For LTO, –30oC 60oC

Safety

Safe to transport at 0V

Usually transported @ 50% SoC to avoid over-discharge
