Abstract

The invention relates to a metal-air fuel battery stack with an easily-replaced open anode. All metal electrodes in the battery pack are positioned in an electrolyte tank; an air electrode is fixed inan electrode groove in the side wall of the electrolyte tank; a base of an anode circulating device is fixed on the electrolyte tank along the upper surface of the side wall of the electrolytic tank;a connecting rod conveying mechanism is fixed above the base through a bracket; a synchronous belt in the connecting rod conveying mechanism circularly operates in the connecting rod conveying mechanism; a lifting lug is fixed on the base; an upper-end connecting rod in the anode connecting rod is fixed on the synchronous belt, the upper-end connecting rod is movably connected with a lower-end connecting rod, and the lower-end connecting rod is fixedly connected with a fixing frame for clamping a metal electrode; and when the anode connecting rod rotates to the lifting lug, the lower-end connecting rod is positioned on the lifting lug, and the fixed frame brings the clamped metal electrode to the upper part of the electrolyte tank. The replacement efficiency of the metal electrode can beimproved.

Description

technical field [0001] The invention relates to the field of metal-air batteries, in particular to an open-type metal-air fuel cell stack with easily replaceable anodes. Background technique [0002] As a power battery widely used at present, the lithium-ion battery pack has the characteristics of high power density and long cycle life, and is widely used in power equipment. However, lithium-ion batteries also have their inherent defects. First, the energy density is low. In the field of electric vehicles that widely use lithium-ion batteries as energy sources, the low energy density of lithium-ion batteries has caused the cruising range of pure electric vehicles to be unsatisfactory; Lithium-ion batteries have higher requirements on the charging and discharging temperature. The general requirements are below 0°C, they cannot be charged, and below -10°C, they cannot work, which causes great inconvenience to the use in cold regions in winter. At the same time, the inherent s...
