Development of new electronic conductivity measurement method for lithium-ion battery electrodeslurry

Abstract

The electrode-slurry preparation process plays an important role to obtain the maximum performance from lithium-ion batteries. A new electronic conductivity measurement method for the electrode-slurry using alternative current impedance measurement was proposed. Electronic conductivity of the electrode-slurry decreased with increasing the electronic conductive additives. It was found that the proposed method is quite useful to characterize the electrode-slurry.
