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 three-electrode metal-air battery test mold with positive anti-fluctuation interference. Background technique [0002] A metal-air (oxygen) battery is a high-efficiency battery with metal as the negative electrode and air (oxygen) as the positive electrode. Because its cathode is mostly made of lightweight porous carbon and other materials, the oxygen, the active reactant of the negative electrode of the partially structured battery, 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 light-weight porous carbon, the oxygen of the negative reactant is obtained directly from the air. At present, the performance of metal-air (oxygen) batteries is characterized by using traditional battery molds to assemble simulated batteries to measure their electrochemical propertie...
