The H6AF from SES AI is an NMC, anode-free pouch cell with 6.3 Ah typical capacity, 24.3 Wh typical energy, and a nominal voltage of 3.85 V. At 25°C, 100% depth of discharge, and C/10, the cell is specified at 525 Wh/kg gravimetric energy density. It weighs 46.0 ± 1.0 g and measures 71.5 ± 1.0 mm long by 48.5 ± 0.5 mm wide, with a thickness of 6.2 ± 0.2 mm at 0% state of charge.
The H6AF supports a maximum continuous discharge rate of 7C and a 15C maximum pulse at 50% state of charge, 25°C, for 30 seconds. Its specified discharge temperature range extends from -30 to 60°C, while charging is specified from 0 to 45°C. Brochure performance data includes discharge profiles at 0.2C, 1C, 3C, 5C, and 7C, temperature-discharge testing at 45°C, 25°C, 0°C, and -30°C, and charge-rate profiles spanning 0.33C through 3C. Cycle-life specifications state more than 70 cycles to 80% SOH at 25°C under 150 psi, compared with more than 10 cycles at 0 psi, using the stated +0.2C/-1C test condition.
