Battery structure and battery pack structure suitable for metal-air batteries

Abstract

The invention provides a battery structure suitable for a metal-air battery and a battery pack structure thereof, including: a casing and a casing cover; the casing includes: a frame, one side of the frame is provided with a positive electrode tab and a metal sheet Negative electrode; electrode, the electrode includes a first electrode and a second electrode, which are respectively arranged on both sides of the frame; the cover includes: a positive pole lug connector, which is detachably connected to the positive pole lug; the negative pole The ear is provided through the case cover, and when the case cover is connected to the housing, one end of the negative pole tab is in contact with the negative pole of the metal sheet, and the other end of the negative pole tab is opened. The hole is detachably connected with the negative electrode lug connecting piece. The invention has a simple structure, the metal-air battery and its battery pack structure are easy to disassemble, have good water retention and air tightness, and the metal-air batteries can be flexibly connected in series and parallel.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a battery structure suitable for a metal-air battery and a battery pack structure thereof. Background technique [0002] With the development of the global economy, the problems of environmental pollution and energy depletion are becoming more and more serious. It is very important to develop renewable energy and energy conversion storage technology. Among emerging battery technologies for energy storage applications, metal-air batteries, which use inexhaustible atmospheric oxygen as the active cathode material, are a promising alternative to conventional power technologies. Since the first electrode of the metal-air battery is a three-phase reaction interface of gas, solid, and liquid, there are high requirements for the leak-proof and air-tightness of the metal-air battery. [0003] Just as the invention patent with the publication number CN1262035C discloses an "air-oxyg...

AI Technical Summary

Problems solved by technology

[0003] Just as the invention patent with the publication number CN1262035C discloses an "air-oxygen-supplied fuel cell stack", the structure design of the current metal-air battery is not perfect, and bolts are usually used to fix the first electrode on the casing, and there is a large artificial error, it is easy to cause liquid leakage due to uneven force on the fixed point

At present, there is no clear introduction to the fixing method of the first electrode and the zinc electrode for the battery structure design without bolts. In the actual use process, glue is usually used to fix the first electrode, which is not only time-consuming and human error is obvious, but also makes the first electrode of the battery Inconvenient disassembly and assembly of electrodes

In addition, there is a gap between the electrode lead-out end and the cover of the current metal-air battery, and the airtightness of the battery is not good, which easily leads to the loss of electrolyte
