Evaluation technology

Based on our experience in battery cell manufacturing and battery systems, we have a system for testing the effects of electrolytes on the battery.
The evaluation is carried out using the following various test devices.

  • VRFB mini cell test device

    It is a test device for one VRFB cell and is used for various performance tests of electrolytes.

  • Evaluation Technology
  • Electrolyte temperature test device

    About 10 sets of mini-cell test equipment stored in a constant temperature bath. Then, the electrolytes are placed into various temperatures (0 °C to 55 °C) in order to evaluate their performance, changes and limit for precipitation.

  • Evaluation Technology
  • Electrolyte stability test device

    This test is to confirm the stability of the electrolyte (eg. precipitation), depending on the temperature of the electrolyte. In order to confirm the stability, a temperature controller and a camera are combined with a microscope to evaluate the stability of the positive electrode V electrolyte (pentavalent) at high temperature and the stability of the negative electrode V electrolyte (divalent) at low temperature. (Stability evaluation detects the precipitation status of precipitated particles by changing the intensity at a specific wavelength.)

  • Evaluation Technology
  • Electrolyte long run test device

    The performance of the electrolyte is evaluated by repeating the charging and discharging of the electrolyte. The number of charge/discharge cycles of the electrolyte can be judged to be stable if the performance is stable after 300 cycles or more.
