Abstract:In order to broaden the operating voltage of the supercapacitors , we prepared a new type of elec-trolyte salt N,N-dimethyl-N-ethyladamantanium tetrafluoroborate by 1-adamantanamine precursor and sim-ple alkylation and ion exchange reaction .And then we prepared a novel electrolyte of supercapacitors combined with common propylene carbonate (PC) solvent.The temperature dependence of the conductivity of the electro-lyte was described by the VFT equation .In addition, the electrochemical performance of the electrolyte was sys-tematically studied by using cyclic voltammetry , alternating current impedance spectroscopy , and galvanostatic charge-discharge tests .We found that the VFT equation was suitable for the electrical conductivity fitting of the system , and the electrolyte has many advantages such as wide electrochemical window , high electrical conductiv-ity, long cycle life , and high charge-discharge efficiency .Experiments show that this new type of amantadine electrolyte is a suitable electrolyte for supercapacitors .
