Advantages of Vanadium Redox Flow Battery (VRFB)

Long-Term Stable Operation

Since there is no need for heat resistance, the battery body have a long lifetime and the design can stand for 20 years. In addition, compared with other batteries which have a limited number of charge and discharge, the number of charge and discharge for RFB is unlimited, and its electrolyte can be used for a long-term. Thus, cost reduction after 20 years is possible.

  • Advantages In Safety Aspect

    The electrolyte is non-flammable and the battery operates in room temperature, so there are no tendency of ignition or explosion.

  • Vanadium Redox Flow Battery
  • Scalability

    Since it is possible to adjust the storage capacity by the amount of electrolyte and the output by the size of the battery cell stack, it can be design freely based on output and charge capacity.

Applications of Vanadium Redox Flow Battery (VRFB)

Storage battery are necessary for:
① Output variation relaxation: To reduce the output fluctuation.
② Smoothing:Controlling the difference power demand between day and night.
③ Emergency power supply:During emergency situation.
④ Smart grid
VRFB is scalable, and it is expected to be utilized for various energy construction in the future.


It accumulates by storing the excess photovoltaic power generation (during day time) or low price electricity during nighttime, then discharges it when photovoltaic power is not generated (example: during nighttime) or in the peak-hours (high demands).
