Embodiment 1

[0031]Preparation of polyacetylene active material: Put polyvinyl chloride (PVC) in a tubular resistance furnace, under the protection of argon, heat at 100°C-500°C for 3-8h, more preferably at 200°C-400°C for 4-6h , most preferably heated at 300°C for 5h, so that the polyvinyl chloride material can be completely dehydrochlorinated to obtain polyacetylene.

Embodiment 2

[0033] Preparation of polypyrrole active substance: add 1.0×10 -5 mol / L surfactant sodium dodecylbenzenesulfonate aqueous solution 30mL, pyrrole 0.06mL, vigorously stirred for 10min, cooled, and added dropwise pre-cooled 138mmol / L ammonium persulfate solution 6.5 mL, after the dropwise addition is completed, store in the refrigerator for 24 hours. Then filter, the filter cake was washed successively with distilled water and absolute ethanol, and vacuum-dried at 80° C. for 12 hours to obtain polypyrrole as a black powder.

Embodiment 3

[0035] Preparation of polyaniline active material: Add 20.27g n-butanol, 10.2g dodecylbenzenesulfonic acid and 11.42g deionized water in turn in the reaction bottle, stir to make them evenly dispersed, add 2.33g aniline solution to the above solution , continue to stir for 2 hours, slowly dropwise add an aqueous solution containing 7.13g of ammonium persulfate to the above solution, dropwise for 1 hour, stir and polymerize for 5 hours, then filter, wash thoroughly with ethanol and deionized water in turn, and dry under vacuum at 80°C 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 with ionic liquid as electrolyte and polymer as positive electrode active material. It belongs to the technical field of electrochemical and chemical power supply products. Background technique [0002] The development of modern science and technology, the shortage of energy and the increasing emphasis on environmental protection require rechargeable batteries with high energy density, low price, abundant resources, safe use, and environmental friendliness. Aluminum battery is one of the batteries with the highest energy density, and has no pollution to the environment. The raw material resources used are abundant, cheap and safe to use, which is in line with the direction of battery development. Metal aluminum is a high-energy carrier as the negative electrode of the battery, with a theoretical specific capacity of 2980mAh / ...
