Abstract

The invention mainly relates to the technical field of electrolyte, and discloses a supercapacitor electrolyte which is manufactured by the raw materials of the following parts by weight: 51-53 partsof 1,4-butyrolactone, 37-39 parts of propylene carbonate, 32-34 parts of 2-methyl-2-propanol, 28-30 parts of glycidyl methacrylate, 24-26 parts of acrylic acid-2-hydroxyethyl ester, 13-15 parts of sec-butyl acetate, 11-13 parts of acrylic acid-2-ethyl hexyl acrylate, 1.6-1.8 parts of ditrifluoromethane lithium sulfimide, 1.1-1.3 parts of lithium hexafluorophosphate and 0.3-0.5 part of benzyl triethylammonium chloride. The supercapacitor electrolyte is safe and environment-friendly, and the situation of volatilization of toxic substances caused by overcharging of the capacitor does not occur inuse so that the environment and the human health can be protected; the electrolyte is appropriate in viscosity, convenient to use and stable in the property, and the specific capacitance is enhancedfor 10.8%, the electric storage capacity is enhanced for 13.5%, the sales volume is enhanced for 11.4% and the economic income is enhanced for 13.7%.

Description

technical field [0001] The invention mainly relates to the technical field of electrolytes, in particular to a supercapacitor electrolyte. Background technique [0002] As people pay more and more attention to the energy environment, supercapacitors, as a new type of energy storage device, are highly valued by governments of various countries. It has both the characteristics of batteries and capacitors. , electrolytes have received significantly less attention. [0003] At present, the electrolytes of supercapacitors mainly include water systems, organic systems, ionic liquids and solid electrolytes, but they all have certain shortcomings. Water system and organic system electrolytes have certain pollution to the environment, and ionic liquids and solid electrolytes are unstable and difficult to promote. Therefore, A new supercapacitor electrolyte is needed. Contents of the invention [0004] In order to make up for the defects of the prior art, the purpose of the presen...
