An organic electrolyte for a wide-temperature high-voltage type super capacitor, and a preparing method therefor. The organic electrolyte is formed by mixing electrolyte salts, an ion liquid and mixed organic solvents. The concentration of the electrolyte salts in the organic electrolyte is 0.5 mol/L to 1.5 mol/L, the concentration of the iron liquid is 0.01 mol/L to 0.05 mol/L, and the mixed organic solvents are formed by mixing acetonitrile and low-melting-point solvents according to a volume ratio being 1: (0.1 to 2). In the preparing method for organic electrolyte, a formula of the super capacitor organic electrolyte is optimized and improved, low-melting-point components added in the organic electrolyte are screened in the design, an ion liquid is added, high-temperature-resistant performance and high-voltage-resistant performance of the organic electrolyte are improved while the solidification point of the organic electrolyte is reduced, the use temperature range is between -65ºC and 70ºC, the use temperature range is wide, the voltage withstanding range can reach approximately 2.75 V, and good low-temperature-resistant performance, high-temperature-resistant performance and high-voltage-resistant performance are realized. The preparing method has simple process steps and high operability, and is applicable to industrial production. |
