Abstract

The invention relates to an open-type metal-air fuel cell group with easily replaceable anodes. All metal electrodes in the battery pack are located in the electrolyte pool; the air electrode is fixed in the electrode tank on the side wall of the electrolyte pool; the base of the anode circulation device is fixed on the electrolyte pool along the upper surface of the side wall of the electrolytic tank; The mechanism is fixed above the base through the bracket; the timing belt inside the connecting rod transmission mechanism circulates in the connecting rod transmission mechanism; the raised bump is fixed on the base; the upper connecting rod of the anode connecting rod is fixed on the timing belt, and the upper connecting rod It can be flexibly connected with the lower connecting rod, and the lower connecting rod is fixedly connected with the fixing frame that clamps the metal electrode; when the anode connecting rod rotates to the lifting bump, the lower connecting rod is located on the lifting bump, and the fixing frame clamps The metal electrodes held are brought over the electrolyte cell. The invention can improve the replacement efficiency of metal electrodes.

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...
