Our batteries have been tested extensively through thousands of cycles. Here are some of the impressive results. Independent third-party tests validate these results.
ReFlex™ has been tested more than any other flow battery model. Smart design decisions to meet NFPA 855, UL1973 and other proven industry standards reflect decades of customer-driven partnerships and field experience that hit the technology sweet-spot. ReFlex™ is produced in semi-automated and fully computerized ISO9001 & ISO14001 rated facilities.
All ReFlex™ deployed to date with almost 1,000,000 hours of operation remain fully available, with the longest systems operating for almost two years. ReFlex™ is the only vanadium flow battery product design for series installation and including seamless bypass feature to increase system-level availability 150X over containerized designs.
Series-connected ReFlex™ autonomously work together to maintain uniform state of charge with patent-pending no-loss state of charge (SOC) matching technology. Rather than using resistors or overcharging to force charge alignment, this no-loss capacity alignment is key to optimal long-term capacity without rest periods.
CHARGE AND DISCHARGE
Comprehensive charge and discharge characterizations for different use cases have validated the flexibility of ReFlex™ to adapt to customer needs. The ideal number of ReFlex™ modules can be easily deployed to match virtually any application requirement.
Mechanical integrity of ReFlex™ was proven by 3rd party testing on a hydraulic shaker table. A production ReFlex™ endured 5G testing through all resonant-frequencies for a full hour. ReFlex™ has also passed tilt-testing to 45° in all directions.
Rigorous 100% discharge testing of a 4 times larger stack, validated zero capacity fade for 3,400 cycles. Detailed materials analysis substantiated no chemical, electrochemical, or mechanical degradation mechanisms.
To prove our battery presents no risk of thermal runaway, we short circuited a fully charged stack. This resulted in a temperature change of just 9°C. Further, 3rd party testing by DNV GL demonstrated the electrolyte is entirely non-flammable. This gives ReFlex™ over flammable storage solutions as some are already being banned in populated areas due to fire and toxic gas hazards. Fire departments classify Lithium-ion fires as defensive fires that cannot be extinguished with the goal being to limit collateral damage. These hazards multiply as storage system capacities increase.
ReFlex™ is designed to proven NFPA 855, UL1973 and other proven industry standards to ensure resiliency, and to simplify system design, production, installation and O&M.
