857 Redox Flow Cell Test System
Scribner
The 857 is an Integrated Turn-Key Test System for Redox Flow Cell Research & Development. It boasts a 20 A current range as well as a multi-range potentiostat for high accuracy. Included with the system is the powerful, user friendly FlowCell™ software for system operation & experimentation.
- 0.07 A, .07 A, 7 A, 20 A current range
- High-current, multi-range potentiostat operates in current- or voltage-controlled operation
- ± 5 V operation for non-aqueous electrolytes
- Charge / discharge cycling & performance characterization
- Four reservoir sizes- 100 mL, 250 mL, 500 mL, and 1 L
- Whole and half-cell voltage, EIS and HFR measurement
- Impedance Analyzer for EIS and HFR measurements during charge, discharge and at OCV
- High-impedance V-sense inputs for whole and half-cell measurements including EIS & HFR
- State-of-charge (SOC) voltage inputs for DC SOC measurement when used with SOC cell
- All non-metallic electrolyte handling system: pumps, electrolyte reservoirs, drain and purge valves
- Cell and electrolyte temperature control up to 50 oC
- Peristaltic pumps with variable flow control including forward and reverse
- Electrolyte shielding with inert gas purge blanket
- Electrolyte reservoir stirring
