Effect of lithium perchlorate concentration on lithium cation transference number in sulpholane solutions

To increase the accuracy of determining the lithium cation transference numbers we proposed to measure them at different values of the polarizing voltage and extrapolate the calculated values to the zero value of the polarizing voltage. It was established that the lithium cation transference numbers increased linearly with the increasing concentration of LiClO4 solutions in sulfolane. It is assumed that the increase in the lithium cation transference numbers takes place due to the change in lithium perchlorate state in sulfolane solution and the mechanism of ion transfer. It was shown that the maximum cation conductivity was achieved at the concentration of lithium perchlorate sulfolane solution of about 2M
