Physicochemical properties of lithium salt solutions in mixtures of sulfolane with dimethyl disulfide

The physicochemical properties of lithium salt solutions in the mixtures of sulfolane with dimethyl disulfide were studied. It was established that the introduction of dimethyl disulfide (5–10% mas.) into sulfolane solutions of lithium perchlorate and lithium trifluoromethanesulfonate leads to the increase in their specific ion conductivity, the decrease in the viscosity, and the reduction in the activation energies of the specific ion conductivity and the viscous flow.

Физико-химические свойства растворов литиевых солей в смесях сульфолана с диметилдисульфидом

Установлено, что введение диметидисульфида (5-10% вес.) в сульфолановые растворы литиевых солей приводит к увеличению электропроводности, снижению вязкости и уменьшению энергий активации электропроводности и вязкого течения. Корригированная электропроводность сульфолановых растворов литиевых солей при введении диметилдисульфида уменьшается, что обусловлено снижением степени электролитической диссоциации солей. Наиболее существенное снижение корригированной электропроводности наблюдается для растворов перхлората лития.

Composite solid electrolytes based on lithium doped N-methyl-N-propylpiperidinium salt

The effect of lithium perchlorate (LiClO4) on the transport and thermal properties of the ternary system consisting of N-methyl-N-propylpiperidinium perchlorate, highly dispersed γ-aluminum oxide (having the specific surface area of 200 m2 /g), and lithium perchlorate was investigated. It was shown that the obtained composites exhibited thermal stability up to at least 190°C.

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.
