The electrolyte acts as the medium that allows the movement of lithium ions between the cathode and anode. High ionic conductivity is to be taken into consideration while designing LiB electrolytes as it ensures easier movement of Li + ions back and forth during the charge and discharge cycle. The electrolyte is made up of two components the solvent and the Li + conducting salt. The solvents used are aprotic and highly polar. Commonly used LIB electrolyte solvents include ethylene carbonate (EC) dimethyl carbonate (DMC), diethyl carbonate (DEC), and ethyl methyl carbonate (EMC). The conducting salts have high solubility in the solvent. It should also be compatible with battery components like the current collector and the separator. Lithium hexafluorophosphate (LiPF6), Lithium-bis(trifluoro methyl sulfonyl)imide (LiTFSI) and lithium-bis(fluoro sulfonyl) imide (LiFSI) are commonly used conducting salts in LiBs. The electrolyte plays a major role in determining the relative ease with which lithium ions can move through it. Various electrolytes used in LiBs have been extensively reviewed .
