Flow battery laboratory

• Engineering & Technology

Tel:+34 943 206 744

An experimental environment dedicated to the development, optimisation, and validation of energy storage systems based on flow battery technologies.

The laboratory has expertise in vanadium-based technologies and other emerging chemistries, enabling work with different configurations and technology readiness levels.

It is equipped with test benches at different scales, ranging from material testing to the validation of complete stacks and their operation under representative conditions.

Equipment

• Test benches at different scales:
  - Small scale (less than 25 cm²) for material testing
  - Intermediate scale (less than 250 cm²) for design validation and scalability assessment
  - Full scale (greater than 250 cm²) for operation of final battery stacks
• Arbin 5V–5A battery cycler (4 channels, up to 20A)
• Arbin 5V–20A battery cycler (4 channels, up to 100A)
• Power electronics (programmable bidirectional power supply and/or inverter)
• Instrumentation for measuring electrochemical variables (voltage, current, State of Charge (SOC), flow rate, pressure, and temperature)
• Balance of Plant (BoP) auxiliary systems (pumps, tanks, and heat exchanger)
• Data acquisition and control systems (BMS)

• Flow battery material testing (electrodes, membranes, and electrolytes): assessment of efficiency, stability, and electrochemical compatibility
• Electrochemical performance analysis: cycling, efficiency, degradation, and service life
• Design, development, and validation of cells and stacks at intermediate scale
• Design and integration of complete systems at full scale (stack, BoP, power electronics, and BMS)
• Independent testing of third-party stacks, including detailed technical reports
