Metal-air battery low-temperature starting adaptive control structure and remote monitoring method

Abstract

The invention discloses a metal-air battery low-temperature starting adaptive control structure and a remote monitoring method, the metal-air battery low-temperature starting adaptive control structure comprises an upper support frame and a lower support frame which are arranged in parallel, the upper support frame is fixedly arranged at the top of the rear side of a galvanic pile box, and the lower support frame is fixedly arranged at the bottom of the rear side of an electrolyte box; guide rails are arranged on the two sides between the two guide rails respectively and provided with an oxygen candle box in a sliding mode. The slideway is arranged on one side of the aluminum air battery, and the spring and the push rod motor are arranged at the upper end and the lower end of the slideway respectively, so that the oxygen candle box can be arranged up and down along the slideway, and the oxygen candle box is in contact with or separated from the electrolyte box by sliding up and down; and the contact area of the oxygen candle box and the electrolyte box is adaptively adjusted, so that the electrolyte is heated, and the low-temperature starting efficiency of the aluminum air battery and the heat dissipation performance of excess temperature are improved.

Description

technical field [0001] The invention relates to the technical field of temperature of metal fuel cells, in particular to an adaptive control structure and remote monitoring method for metal-air battery low-temperature startup. Background technique [0002] At present, aluminum-air batteries are an important branch of metal-air batteries, which use aluminum as the negative electrode of metal-air batteries. Since metal aluminum is abundant in my country, its cost is low and its acquisition is relatively easy, this type of battery has good application and development prospects. The reaction materials of aluminum-air batteries mainly include aluminum-air anode plate, air electrode and KOH alkaline electrolyte. In the battery, the aluminum alloy first reacts with the hydroxide ions in the strong alkaline electrolyte to form aluminum hydroxide, and releases free electrons at the same time. Free electrons flow into the air electrode and react with water to form new hydroxide ions...

AI Technical Summary

Problems solved by technology

Of course, the disadvantages of this scheme are: (1) The combustion of the oxygen candle is uncontrollable. After ignition, the combustion must be stopped until the chlorate is completely decomposed.

(2) The heat released by the oxygen candle is too large, and the temperature of the electrolyte can be rapidly increased in a low-temperature environment, but after the aluminum-air battery works normally, the heat generated is harmful heat and needs to be discharged in time

(3) This type of aluminum-air battery is mostly used in the long-term standby state, how to monitor the working life of the oxygen candle for a long time

However, the existing research cannot achieve different degrees of heating effects according to the real-time temperature values ​​of the low temperature environment

Furthermore, there are relatively few studies on how to ensure the long-term effectiveness of oxygen candle boxes for long-term backup aluminum-air batteries
