Abstract

Abstract : Correlation between conductivity the components of electrodes mass of Li batteries and electrochemical properties of these electrodes and Li batteries based on these electrodes have been investigation. The various types of the graphene and the graphite have been used as conductive additives for cathodes (positive electrodes). Various types of sulfide, manganese dioxide, lithium manganese spinel, and sulfides have been used as active materials of electrodes of Li batteries. The conductivity of powder materials have been investigated using the innovating non-contact non-destructive electromagnetic method. Impedance, galvanic cycling and current-voltage characteristics of the electrodes have been investigated.
