Abstract

The invention provides a metal-air battery provided with an electrolyte concentration detector. The metal-air battery comprises a housing (1), and a metal-air battery unit (2); the metal-air battery unit (2) comprises a battery housing (3), electrolyte (4), a metal electrode used as the positive electrode, and an air electrode used as the negative electrode; the upper end and the lower end of one side of the battery housing (3) are provided with a liquid inlet pipe (5) and a liquid outlet pipe (6) respectively; the electrolyte concentration detector (7) is arranged in the housing (1), and is connected with a concentration detecting rod (8) via wire; the concentration detecting rod (8) is inserted into the electrolyte (4) via a lower end opening of the battery housing (3); the housing (1) is provided with an air port (9); the housing (1) is provided with an output voltage terminal (10); an output terminal of the metal-air battery unit (2) is communicated with the output voltage terminal (10); and power line of the electrolyte concentration detector (7) is communicated with the output voltage terminal (10). According to the metal-air battery provided with the electrolyte concentration detector, electrolyte concentration can be adjusted at any time; battery service life is prolonged; and high performance of air batteries is realized fully.

Description

technical field [0001] The invention belongs to the technical field of air battery devices, in particular to a metal-air battery with an electrolyte concentration detection device. Background technique [0002] Air batteries have many advantages such as cheap and easy-to-obtain raw materials, stable discharge voltage, high energy and environmental protection, so they are widely used at present. However, during the use of the air battery, it is necessary to let the positive electrode into the air, so there is an air intake hole on the air positive electrode. This structure often causes the moisture inside the battery to volatilize, causing the battery to dry up and the moisture in the air to enter the inside of the battery and dilute it. The problem of the electrolyte has seriously affected the service life of the zinc-air battery and the full play of its superior performance. Contents of the invention [0003] The purpose of the invention is to overcome the problem that t...
