Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 The metal-air battery system shown mainly includes a casing (not shown in the figure), an air diffusion electrode 2, a metal electrode 1, an electrolyte solution 6 containing an alkaline electrolyte, and an electrolyte acceleration device 7, etc.

[0016] Wherein, the air diffusion electrode 2 and the metal electrode 1 are accommodated in the cavity formed by the casing. Metal electrode 1 adopts conventional foam matrix, its thickness is 0.1~10mm, its porosity is 70~98%, and its material is Ni, Cu, NiCrFe, ZnCu, NiCu, NiCrW, NiFe or Ti; Also preferably on its surface A non-conductive layer is formed, and the non-conductive layer is a metal oxide layer or a porous polymer film layer. By forming a non-conductive layer on the foam substrate, when it is assembled with a cathode and an electrolyte to form a metal-air battery, dendrites can be avoid...

Abstract

The invention relates to a metal-air battery system, which includes a housing, an air diffusion electrode, a metal electrode, an electrolyte solution containing an alkaline electrolyte, and an electrolyte accelerating device. The first channel of the electrolyte; the first channel communicates with the outside of the casing through an external conduit to form an electrolyte circulation circuit for accommodating the flow of the electrolyte; the electrolyte acceleration device is connected to the electrolytic In the liquid circulation circuit, it also includes a second channel formed on the other side of the metal electrode and communicated with the first channel through the metal electrode, the second channel communicates with the outside of the housing through the The external conduit is connected, and the metal electrode is a foam matrix, which avoids the phenomenon of irregular consumption of the metal electrode, is conducive to improving the charging and discharging power and the stability of the battery, and alleviates the growth of metal dendrites to prolong the service life.

Description

technical field [0001] The invention belongs to the field of metal-air batteries, and relates to a battery system, in particular to a metal-air battery system. Background technique [0002] With the rapid development of mobile electronic devices, everything from mobile phones and laptops to electric vehicles rely on batteries to provide power. At present, the energy density of batteries is the technical bottleneck that limits the battery life of various electronic devices. Metal-air batteries are ideal candidates for next-generation batteries due to their extremely high theoretical energy density. Metal-air batteries generally include metal electrodes, air-diffusion electrodes, and electrolytes, among which the electrolyte plays an important role in metal-air batteries. Due to the limitation of the electrolyte, the existing metal-air batteries usually have low power, and the distance between the cathode and anode changes slightly as it is continuously consumed, resulting i...
