There are various types of storage batteries, but our focus is on large capacity storage battery system called redox flow batteries, and we have been engaged in research and development especially in vanadium redox flow battery (VRFB),
VRFB is a superior battery in various aspects, but the cost was impeding the growth because the price of the electrolyte material (vanadium) is unstable.
Based on our research, in order to solve this problem, we found a way to recover vanadium from industrial waste which is combustion soot (EP soot) and established a technology to efficiently producing electrolyte by vanadium recovery that may lead into a stable and cheap electrolyte production.
Research on RFB with various types of electrolyte is going progressively, and if the price of vanadium can be secure/maintain at a low price, it will become a major factor of RFB growth. We will continue doing research, development and manufacture, so that we can make a significant contribution to the growth of RFB, especially from the electrolyte factor.
