Abstract

The invention relates to a battery taking bromine-containing ionic liquid as a positive electrode active material and an assembling method thereof. The battery comprises a positive electrode chamber and a negative electrode chamber, which are separated through a cation-exchange membrane; electrolyte of the positive electrode chamber comprises the bromine-containing ionic liquid; ionic liquid electrolyte is injected into the negative electrode chamber. The bromine-containing ionic liquid in the battery provided by the invention is obtained by taking a bromine elementary substance and organic salt to react. According to the battery provided by the invention, the ionic liquid is used as the electrolyte, the bromine-containing ionic liquid is used as the positive electrode active material, aluminum or magnesium is used as a negative electrode, and aluminum and magnesium electrodes have no passivation films in the ionic liquid so that the battery has relatively high reversibility; the battery is a cheap, environment-friendly and high-energy-ratio battery system.

Example Embodiment

[0053] Example 1
[0054] A battery includes a positive electrode chamber and a negative electrode chamber separated by a Nafion membrane; the electrolyte in the positive electrode chamber includes tetraethylammonium tribromide, and the negative electrode chamber is injected with an ionic liquid electrolyte; carbon nanotubes are inserted into the positive electrode chamber The positive electrode, the negative electrode chamber is immersed with an aluminum negative electrode.
[0055] The ionic liquid electrolyte is prepared by mixing anhydrous aluminum chloride and 1-ethyl-3-methyl-imidazolium chloride in a molar ratio of 2:1.
[0056] The assembling method of the battery specifically includes the following steps:
[0057] (1) The carbon nanotube positive electrode, tetraethylammonium tribromide, and ionic liquid electrolyte are placed in a glove box filled with argon;
[0058] (2) Use Nafion membrane and sealing ring for lamination and assembly;
[0059] (3) Insert the positive electrode of the carbon nanotube into the positive electrode chamber, and inject tetraethylammonium tribromide into the positive electrode chamber of the battery; the ionic liquid electrolyte is injected into the negative electrode chamber of the battery, and the aluminum negative electrode is immersed in the ionic liquid electrolyte, and then is sealed, formed, and cleaned. That is, the battery is obtained.
