Lithium bis(oxalato)borate as an electrolyte for micromesoporous carbide-derived carbon based supercapacitors

► Lithium bis(oxalato)borate (LiBOB) as an electrolyte for EDLCs. ► High energy and power density EDLCs based on mixed carbonate solvents (EC + DMC). ► Mo2C derived micro/mesoporous carbon as an electrode material. ► Ideal capacitive behavior at moderate cell voltages ΔV < 3.0 V. ► High diffusion resistance due to big molar volume of anions.
