Principle of Redox Flow Battery (RFB) System- Key Features -
Product Lineup & Layout
» Cost Reduction The containerization of the flow battery reduces the cost of transportation and local commissioning.
» Lifetime & Cycle-basis Economic ValuesBenefits stacking from multiple battery services by unlimited number of cycles over its long lifetime
» Flexible Combination of Output & CapacityPower intensive mode: Up to 200% Design flexibility: Easy expansion of capacity
» Reduction in Installation AreaThe two-storey design and increase in battery output reduce the installation area of our flow battery system.
Example: 500 kW × 3h (1,500 kWh) Model
» The state of charge (SOC) can be monitored on a real time basis. It is directly measured during operation by electromotive force (voltage) at the monitoring cell.
» No significant deposition of solution through chemi-cal reactions in the Vanadium redox flow battery
» Our redox flow battery consists of non-flammable materials and electrolyte.
» No constraint of system operation on depth of discharge (DoD) and number of cycles
— Depth of Discharge: 100% — Unlimited number of cycles over lifetime
» Electrolyte: Vanadium sulphate aqueous solution — Non-flammable liquid — The mixing of positive and negative electrolyte does not result in ignition.
» Cell stacks and pipes: Polyvinyl chloride (PVC) — Non-explosive (Ignition point: 455°C) — High self-extinguishing capability
Easy monitoring & management of the available capacity even in a complex operation
Redox: Reduction & Oxidation reactionsFlow: Electrolyte flows through electrochemical cells
Long design lifetime of 20 years&
Semi-permanent use of electrolyte
Extremely low possibility of fire resulting from the flow battery materials and electrolyte
Highly capable of longlife multiple-cycle operations
