Principle of Redox Flow Battery (RFB) System - Key Features - Concept Generation V5+/ V4+ Electrolyte Tank Pump System Configuration Container Type of Redox Flow Battery » Cost Reduction The containerization of the flow battery reduces the cost of transportation and local commissioning. » Lifetime & Cycle-basis Economic Values Benefits stacking from multiple battery services by unlimited number of cycles over its long lifetime » Flexible Combination of Output & Capacity Power intensive mode: Up to 200% Design flexibility: Easy expansion of capacity » Reduction in Installation Area The two-storey design and increase in battery output reduce the installation area of our flow battery system. Product Lineup Example of System Layout Example: 500 kW × 3h (1,500 kWh) Model 1177m Charge Discharge Load V2+/ V3+ Electrolyte Positive Negative V2+ V3+ Heat exchanger Pump PCS Cell Grid AC PCS DC Cell stack V5+ V4+ H+ Tank Charge Discharge Electrode Membrane Configuration of a single cell Electrode Electrode Pump Electrolyte tank Frame Membrane Bi-polar plate Feature 1: Accurate Monitoring of SOC Feature 2: Fire Safety » 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. » Our redox flow battery consists of non-flammable materials and electrolyte. » 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 Feature 4: No operational constraint on cycle life » No constraint of system operation on depth of discharge (DoD) and number of cycles — Depth of Discharge: 100% — Unlimited number of cycles over lifetime Monitoring Cell V PCS AC250kW AC250kW AC250kW AC750kWh AC1,125kWh AC1,500kWh 6.1m×4.9m×6m 9.1m×4.9m×6m 12.2m×4.9m×6m Easy monitoring & management of the available capacity even in a complex operation System Size & Installation Area Output Capacity Installation Area Feature 3: Long-life operation » No significant deposition of solution through chemi- cal reactions in the Vanadium redox flow battery Positive Electrode Negative Electrode 1MW 1MW 10MW 3MWh 6MWh 45MWh 15m×17m 27m×17m 103m×27m 1MW 4.5MWh 21m×17m Charge 4+ 5+- 3+ V V +e Charge V +e- V2+ Discharge Discharge 10MW 30MWk 85m×27m 8m 10MW 60MWh 131m×27m 01 02 e- Positive flow Negative flow e- Redox: Reduction & Oxidation reactions Flow: Electrolyte flows through electrochemical cells Basic Specification per Module Capacity Dimensions 3 hours model 6 hours model Output 4.5 hours model Extremely low possibility of fire resulting from the flow battery materials and electrolyte Long design lifetime of 20 years & Semi-permanent use of electrolyte Highly capable of longlife multiple-cycle operations Product Lineup & LayoutPDF Image | Redox Flow Battery Sumitomo
