Product Overview

The 5.5 Ah square-shell sodium-ion power cell combines a 2.90 V nominal voltage with high-rate charging and discharging capability for compact power battery designs.

The cell is specified with a 148 x 18 x 65 mm class form factor, 10C continuous charging, 30C continuous discharging and a cycle-life target of at least 45,000 cycles under the listed operating mode.

Performance Features
  • 5.5 Ah rated capacity and 2.90 V nominal voltage.
  • 2.0-3.45 V operating voltage at or above 0 C; 1.5-3.45 V below 0 C.
  • 10C continuous charging and 30C continuous discharging.
  • 40C pulse charging and 75C pulse discharging for 10 seconds.
  • At least 80% capacity retention after 45,000 cycles under 20-80% SOC and 4C charge / 4C discharge conditions.
