Method for assembling a hybrid lithium supercapacitor

摘要: The invention relates to a method for developing hybrid supercapacitor, said including: at least step of assembling together negative electrode, made one non-porous carbon material, and positive porous electrodes being separated from each other by means separator impregnated with liquid electrolyte containing lithium salt dissolved in solvent; then first charging step, wherein is characterized that: a) the lithium-ion concentration electrolyte, before greater than or equal 1.6 mol/L; b) 50 wt % contains selected among LiTFSI derivatives thereof; c) 80 vol solvent cyclic alkyl carbonates, acyclic lactones, esters, oxalanes, mixtures thereof, it understood that 20 ethylene carbonate; d) material electrode materials, mean size pores which 0.7 nm has specific surface area more 700 m2/g; e) materials capable inserting ions having no 150 f) after assembly supercapacitor carried out plurality consecutive steps up maximum voltage (Umax) between 4 5 volts, current density varying 10 mA/g 400 mA/g. Each following an intermediate self-discharge discharge lower
