Three-electrode metal-air battery testing mold with positive electrode resisting to fluctuation interference

Abstract

The invention discloses a three-electrode metal-air battery testing mold with a positive electrode resisting to fluctuation interference. The mold comprises a counter electrode wire (1), a counter electrode rubber plug (2), a three-neck flask (3), a counter electrode (4), a reference electrode wire (5), a reference electrode rubber plug (6), a reference electrode (7), a working electrode wire (8),a ventilating guide pipe (9), a working electrode sleeve (10), a working electrode assembly (11), injected gas phase air bubbles (12) and electrolyte (13). With the traditional three-neck flask (3) being a mold basis, a working electrode resisting to liquid surface fluctuation caused by gas injection is designed based on the principle of floating, and the mold is simple in structure and capable of being operated at normal voltage to prevent the electrolyte from leaking under high voltage. Injected air can fully make contact with a reaction interface, so that testing efficiency is improved. Meanwhile, by adopting the designed working electrode sleeve, the counter electrode and the reference electrode are protected, and remaining gas can be further collected.

Description

technical field [0001] The invention relates to the field of metal-air batteries, in particular to a test mold for a three-electrode metal-air battery with positive pole anti-fluctuation interference. Background technique [0002] A metal-air (oxygen) battery is a high-efficiency battery that uses metal as the negative electrode and air (oxygen) as the positive electrode. Because its cathode is mostly made of lighter porous carbon and other materials, the active reactant oxygen of the negative electrode of the battery with a partial structure can be ventilated or directly obtained from the air. Compared with traditional metal batteries, it can have higher energy density. Because its cathode mostly uses lighter porous carbon, the oxygen of the negative electrode reactant is directly obtained from the air. At present, the characterization of metal-air (oxygen) battery performance mostly uses traditional battery molds to assemble simulated batteries and measure its electroche...
