Alkali Hydroxide Triple Phase Flow Batteries (3PFB)
Technology Description:
Georgia Tech Research Corporation is developing an alkali hydroxide triple phase flow battery (3PFB) to enable reversible operation of ultrahigh energy density battery chemistries. The approach takes inspiration from fuel injectors in internal combustion engines and from conventional flow batteries. The proposed design leverages innovative pumping and handling of molten alkali metal and hydroxide species to maximize the volume of reactants over inactive components and thus increase energy density.
Market Impact Potential:
Georgia Tech Research Corporation’s design would address the electrification of aviation, shipping, and rail. The 3PFB cells will make use of simple and inexpensive materials, and the molten alkali hydroxides are air-stable, and therefore, no reactions with oxygen or nitrogen gas are anticipated.
