The voltage of lithium - intercalation reaction, impedance and structural stability of intercalation - type cathode material were analysed and calculated. theoritical results show that the reaction voltage depends on the content of lithium and the bond energy, and that the key ways to lower the electrode impedance are to increase the electronic conductivity of the electrode and the diffusion coefficient of lithium ion in the host and to decrease the size of powder. in addition, the thermal stability of lithium - insertion structure can be improved by using crystallographic co - lattice theory and doping treatment
