Various composites including (1-x-y) LiNi0.7Co0.3O2, xLi2MnO3 and yLiCoO2 systems were synthesised using the sol--gel method. Stoichiometric weights of the LiNO3, Mn(Ac)2·4H2O, Co(Ac)2·4H2O, Ni(NO3)2·6H2O for preparing of 28 samples have been used. We found that the sample "Li1.167Ni0.117Co0.699Al0.017Mn0.167O2" with Al doped is the best composition for cathode material in LIBTs. Obviously, the weight of cobalt used in this sample is lower compared to LiCoO2 which is an advantage in view point of cost and toxicity. Charge-discharge characteristics of the mentioned cathode materials were investigated by performing cycle tests in the range of 2.4--4.6 V. Our results confirmed that this kind of system can help removing the mentioned disadvantage of cobalt with high efficiency. |
