Chemical engineering professor Dr. Jodie Lutkenhaus and chemistry assistant professor Dr. Daniel Tabor has published their findings about lithium-free batteries in“There would be no battery fires anymore because it’s water-based,” Lutkenhaus said. “In the future, if materials shortages are projected, the price of lithium-ion batteries will go way up.
According to their article, redox-active, non-conjugated radical polymers are promising candidates for metal-free aqueous batteries because of the polymers’ high discharge voltage and fast redox kinetics. The reaction is complex and difficult to resolve because of the simultaneous transfer of electrons, ions, and water molecules.
“Theory and experiment often work closely together to understand these materials. One of the new things that we do computationally in this paper is that we actually charge up the electrode to multiple states of charge and see how the surroundings respond to this charging,” Tabor said.
