Abstract

A biomass-based colloidal electrolyte and a biomass-based colloidal electrolyte supercapacitor belong to the technical field of supercapacitors. The preparation method of the colloidal electrolyte is to mix seastone cauliflower with deionized water and heat it to boiling, dissolve the seastone cauliflower in deionized water, boil it with a low fire to form a sol, and then mix it with different types of electrolytes to form a colloidal electrolyte . The supercapacitor assembled with the biomass-based colloidal electrolyte has the advantages of low internal resistance and high power density. In addition, the biomass-based colloidal electrolyte has the characteristics of simple preparation process, safety and environmental protection, and easy realization of large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of supercapacitors, and in particular relates to a biomass-based colloidal electrolyte and a biomass-based colloidal electrolyte supercapacitor. Background technique [0002] Supercapacitor is a new type of energy storage device with higher energy density than traditional capacitors and higher power density than secondary batteries. It has the advantages of fast charging and discharging speed, high efficiency, long cycle life, wide operating temperature range, high safety, etc., and has broad application prospects in the fields of electric vehicles, weapons and equipment, aerospace, and power energy storage. [0003] At present, supercapacitors use aqueous or organic electrolytes. During transportation and use, the shell of supercapacitors is prone to damage and electrolyte leakage occurs. In addition, the corrosion of the electrolyte may also cause damage to the casing of the supercapacitor. The leakage o...
