Non-contact detection methods for the electrical conductivity of energy storage materials

Energy issues have always been one of the key issues that humans pay close attention to. The storage and conversion of energy are crucial steps in solving energy problems. Therefore, research on supercapacitors with excellent performance has always been a hot topic, among which the detection of electrical conductivity is a key issue in the research on supercapacitors. Based on the principle of inductive thermoacoustic detection, this paper proposes a non-contact detection method for the electrical conductivity of energy storage materials. The detection principle of this method was studied through theoretical analysis, and then simulations and experiments were carried out to verify the feasibility of this method, opening up a new technical approach for the detection of the electrical conductivity of energy storage materials and being of great significance for promoting the further development of energy storage materials.
