Kaixiang Lin, a team member and one of the study's authors, said they considered "about a million different quinones" but ended up developing a whole new class of electrolyte material. He also added that it's simple to make and can be manufactured in large quantities for cheap. Flow batteries store energy in solutions kept in tanks, you see. The bigger the tank, the larger the amount of energy it can hold, so this molecule could lead to high-capacity batteries. Lin and his fellow researchers plan to study their creation more closely, but they're also still on the lookout for other organic molecules that can outperform it.
