| Abstract: | In order to measure the content of the manganese and cobalt in the cathode material LiCo_(0.1)Mn_(1.9)O_4 for Li-ion Battery accurately and quickly, we conducted the experiments for the choice of the acidic dissolving agent. Complexometry was adopted to measure the content of manganese by the condition-selection experiment.The measurement of the total content of manganese and cobalt was by returns complexometry. Finally, we made use of subtraction to compute the content of cobalt. According to the accurate result in this paper, we conclude that it is a simple, prompt method of precision. |
