The Gibbs free energy of adsorption of Li and K atoms/ions on surfaces of CNT(8, 0), CNT(8, 0)-MnO and CNT(8, 0)-CdO2 are calculated. The cell voltages(Vcell) of Li and K atoms/ions adsorption on studied surfaces are examined. The Vcell of LIBs with metal-oxides attached to CNT(8, 0) as anode electrodes are higher than those KIBs. The adsorbed metal oxides(MnO and CdO2) on CNT(8, 0) increased the charges, electronic conductivity and Vcell of LIB and KIB, efficiently. The CNT(8, 0)-CdO2 as anode electrodes in LIB and KIB is proposed.展开更多
