Embodiment 1

[0033] The positive active material is carbon nanotube (CNT), and the binder is polytetrafluoroethylene (PTFE). The mass ratio of the two is 9:1, and alcohol is sprayed to mix the two evenly, and finally a gelatinous substance is obtained. The above-mentioned jelly-like substance is evenly coated on the molybdenum sheet of the positive electrode current collector, and placed in an oven at 120° C. for about 24 hours to continue drying to obtain the positive electrode of the battery used in the present invention. Take 0.25mm thick Cu 11 Al 9 alloy, ultrasonically cleaned in absolute ethanol for several hours and then dried to obtain the negative electrode of the battery. The separator is glass fiber, and the electrolyte is AlI 3It is mixed with 1-butyl-3-methylimidazolium chloride at a molar ratio of 1.5:1 to form an aluminum-containing non-aqueous electrolyte. The electrolytic cell is a soft bag packed with aluminum-plastic film. The assembly of the whole battery is carrie...

Embodiment 2

[0035] The positive active material is WS 2 , mix it with the conductive agent Super-P and the binder polytetrafluoroethylene (PTFE) at a mass ratio of 7.5:1.5:1, disperse in a certain amount of alcohol, and ultrasonically mix the three evenly for 60 minutes. The mixture was baked in a 60°C oven until it became gelatinous, and the gelatinous active material was evenly coated on the molybdenum sheet of the positive electrode current collector, and the obtained positive electrode was dried in an oven at 120°C for about 24 hours to obtain the positive electrode for the present invention. The negative pole is metal aluminum with a thickness of 0.20 mm that has been ultrasonically cleaned in alcohol for several hours. Separator is glass fiber, electrolyte is AlCl 3 Aluminum-containing non-aqueous electrolyte prepared by mixing with 1-propyl-3-methylimidazolium chloride salt in a molar ratio of 1.3:1. The electrolytic cell device is made of a glass bottle with a polytetrafluoroeth...

Description

technical field [0001] The invention belongs to the technical field of new green energy batteries, and in particular relates to a non-aqueous solution aluminum ion secondary battery and a preparation method thereof. Background technique [0002] In recent years, with the continuous reduction of non-renewable energy sources (such as oil, coal, natural gas) and the environmental pressure and greenhouse effect brought about by their use, the development and utilization of clean and renewable energy sources has become a current research hotspot. Among them, electric energy has become a key factor in the development and utilization of renewable and clean energy because it is at the core stage of various energy conversions. However, to realize the efficient utilization of these electric energies, the problem of electric energy storage is involved. The rechargeability and dischargeability of secondary batteries is currently the most effective and promising way to solve electrical ...
