The wide-spread proliferation of aqueous MXene-based supercapacitor has been largely shadowed by the limited cell potential window(typically in the range of 0-0.6 V).To address this baffling issue,designing asymmetric supercapacitor(ASC)is proposed as a rational strategy to enlarge the potential window(thus energy density)of individual cell in aqueous *** this date,however,it still remains a great challenge to develop easy fabricating,3D nanostructured,and pseudocapacitive cathode materials that can perfectly match with MXene *** this work,we propose a supramolecular strategy to construct conducting polymer hydrogel(CPH)with highly interconnected 3D nanostructures and large pseudocapacitance,which can finely match with 2D Ti_(3)C_(2)T_(x).The as-assembled CPH//Ti_(3)C_(2)T_(x) ASCwith CPH cathode and MXene anode can operate in a broadened potential window of 1.15 V in aqueous PVA/H_(2)SO_(4) gel electrolyte with remarkably improved energy density of 16.6μWh/cm^(2)(nine times higher than that of symmetric MXene supercapacitor).Additionally,this ASC exhibits outstanding cyclic stability with no trackable performance decay over 30,000 galvanostatic charge and discharge *** is demonstrated in this work that employing positive CPH electrode is a feasible yet promising strategy to enhance the potential window and energy density of aqueous MXene supercapacitors.

Although room temperature ionic liquids(ILs)have emerged as potential next-generation electrolytes for their wide electrochemical stability window(ESW),the trade-off between this window and viscosity has hindered their widespread use in energy storage ***,we present for the first time that such a trade-off can be balanced by mixing two ILs with the common anion([NTf_(2)]^(-))but different cations([EMIM]^(+) and[N1114]^(+))***[EMIM]cation-based IL possesses low viscosity while the[N1114]cation-based IL exhibits wide *** the concentrations of each IL in the mixtures can result in different electrolyte properties,we demonstrate a systematic approach by exploring the properties of various concentration *** addition,the corresponding cell voltage of their resulting graphene supercapacitors(SCs)accompanied based on the interaction between the binary ionic liquid and the electrodes,and the associated electrochemical performance were studied to determine the optimum electrolyte system for the highest SC energy *** well-balanced viscosity/ESW trade-off is achieved in binary IL consisting 50 vol%[EMIM][NTf_(2)]and 50 vol%[N1114][NTf_(2)]as evident from the extraordinary electrode specific capacitance of 293.1 F g^(-1) and the ultrahigh SC energy density of 177 Wh kg^(-1),which approaches that of a lithium-ion battery.
