RELAXATION AND IMPEDANCE CHARACTERISTICS OF LITHIUM AND LITHIUM-ION SECONDARY BATTERIES AT THE DIFFERENT STAGES OF CYCLING

摘要

Information about the properties of the single components of lithium power source-cathode,anode,electrolyte is insufficient for predicting the characteristics of an actual lithium battery.The characteristics of lithium battery are determined by a number of additional factors:the resistance of the electrode/electrolyte interface;by the volume redistribution of the components of electrode structure during discharge/charge of the power source;concentration and electric fields appearing in porous structures in the absence of convection.
