Embodiment 1

[0031] Preparation of polyacetylene active material: Place polyvinyl chloride (PVC) in a tubular resistance furnace, under argon protection, heating at 100℃-500℃ for 3-8h, more preferably 200℃-400℃ for 4-6h It is most preferable to heat at 300°C for 5 hours to completely remove hydrogen chloride from the polyvinyl chloride material to obtain polyacetylene.

Embodiment 2

[0033] Preparation of polypyrrole active substance: add 1.0×10 to the reaction flask -5 mol / L surfactant sodium dodecylbenzene sulfonate aqueous solution 30mL, pyrrole 0.06mL, vigorously stir for 10min, cool, add dropwise the pre-cooled 138mmol / L ammonium persulfate solution 6.5 under vigorous stirring at 0℃-5℃ mL, after the dripping is completed, store in the refrigerator for 24h. Then it was filtered, the filter cake was washed with distilled water and absolute ethanol successively, and vacuum dried at 80° C. for 12 hours to obtain black powdered polypyrrole.

Embodiment 3

[0035] Preparation of polyaniline active material: add 20.27g n-butanol, 10.2g dodecylbenzene sulfonic acid and 11.42g deionized water into the reaction flask, stir to make it evenly dispersed, add 2.33g aniline solution to the above solution , Continue to stir for 2h, slowly add an aqueous solution containing 7.13g of ammonium persulfate to the above solution, dropwise in 1h to complete, stir and polymerize for 5h, then filter, wash thoroughly with ethanol and deionized water in turn, and dry in vacuum at 80℃ 12h to obtain polyaniline powder.

Abstract

The invention discloses an aluminium polymer secondary battery and a preparation method thereof. The aluminium polymer secondary battery is prepared by taking metallic aluminium or aluminium alloy, preferably foamed aluminium as the negative pole, vulcanized polyvinyl chloride or carbon-sulfur composite materials as the positive active materials, and halogen aluminic acid ionic liquid formed by aluminum subhalide and one of hyamine, phosphonium actericideor, or sulfur actericide as the electrolyte solution. The battery has the advantages of high energy density, good cycle performance, environment protection, no pollution during the preparation, low cost, simple process and favorable application prospect.

Description

Technical field [0001] The invention relates to a secondary aluminum-polymer battery. More specifically, it relates to a rechargeable aluminum battery using ionic liquid as electrolyte and polymer as positive electrode active material. It belongs to the technical field of electrochemistry and chemical power products. Background technique [0002] The development of modern science and technology, energy shortage, and increasing emphasis on environmental protection require high energy density, low price, abundant resources, safe use, and environmentally friendly rechargeable batteries. Aluminum battery is one of the batteries with the highest energy density, and it does not pollute the environment. The raw materials used are abundant, low in price, safe to use, and in line with the development direction of batteries. As the negative electrode of the battery, metal aluminum is a high-energy carrier, with a theoretical specific capacity of 2980mAh / g, second only to lithium (3870mAh...
