METHOD FOR EVALUATING CONDUCTIVE MATERIAL FOR USE IN RECHARGEABLE BATTERY

Abstract: a method for evaluating a conductive material for use in a rechargeable battery is provided. the rechargeable battery includes an electrode plate in which a mixture layer, containing an active material and the conductive material, is formed on a substrate. the method includes preparing a paste containing simulated primary particles and the conductive material. the simulated primary particles are formed of an insulative material that simulates the active material of the rechargeable battery. the method further includes applying the prepared paste to a simulated substrate that simulates the substrate of the rechargeable battery, drying the applied paste to prepare a test coating containing the simulated primary particles, and measuring a coating resistance r(��cm) to evaluate the conductive material. the coating resistance corresponds to a surface resistance of the test coating.
