Low Temperature Conductivity Study of MultiOrganic Solvent Electrolyte for Lithium-Sulfur Rechargeable Battery Application: Recent Study | Chapter 12 | Current Research and Development in Chemistry Vol.1
The
conductivity of an electrolyte plays a significant role in deciding the
performance of any battery over a wide temperature range from –40°C to 60°C. In
this work, the conductivity of lithium bis (trifluoromethanesulfonyl) imide
(LiTFSI) at a varied salt concentration range of 0.2 M to 2.0 M in a
multi-solvent organic electrolyte system over a wide temperature range –40°C to
60°C are reported. The mixed solvents used were 1, 3-dioxolane (DOL), 1,
2-dimethoxyethane (DME), and tetraethylene glycol dimethyl ether (TEGDME) with
an equal ratio of DOL: DME: TEGDME (1:1:1 by volume). The experimental analysis
performed over the wide temperature range revealed the maximum conductivity at
salt concentrations ranging from 1.0 M to 1.4 M for equal molar solvents. The
optimum salt concentration and maximum conductivity in a different solvent
composition ratio (i.e., 3:2:1) for all the temperatures is reported herein.
The temperature-dependence conductivity of the salt concentration did not fit
the Arrhenius plot but it resembled the Vogel-Tamman-Fulcher plot behaviour.
The present conductivity study was carried out to evaluate the overall operable
temperature limit of the electrolyte used in the lithium-sulfur battery.
