Dramatic Drop in Cell Resistance through Induced Dipoles and Bipolar Electrochemistry

Journal of the Electrochemical Society, 2022
The use of slurries of conducting particles has been considered a way to extend the electrode area in some energy storage electrochemical cells. When suspensions of conducting particles are used in electrolytes a decreased impedance is observed, even ...
