Abstract

Lithium cells based on NMC cathodes or graphite anodes and ionic liquid-based electrolyte mixtures are investigated. The electrode tapes, using water-soluble natural binders, as well as the ionic liquid materials, are prepared through eco-friendly routes involving H2O as the only processing solvent. The Li/NMC and Li/graphite half-cells are studied by cyclic voltammetry, impedance spectroscopy and galvanostatic cycling tests at different temperatures. The results herein reported, demonstrate the performance improvement in terms of cycling behavior and ageing resistance, granted by the ionic liquid mixtures with respect to the electrolytes reported in literature based on a single ionic liquid. © 2016 Elsevier B.V.
