Problems solved by technology

[0003] First of all, the overvoltage is high, mainly due to the high overvoltage of the oxygen evolution reaction in the discharge process, and RuO2 is a good and efficient catalyst for the oxygen evolution reaction, but its catalytic activity for the redox reaction is low; MnO2 is A better oxygen reduction catalyst, but the catalytic activity of the oxygen evolution reaction is low; therefore, the composite of MnO2-RuO2 can be used as an efficient dual-function catalyst

Abstract

The invention discloses a refrigerator with a storage battery power supply function. The refrigerator comprises a refrigerator body, a refrigerating system and a storage battery are arranged in the refrigerator body, and the storage battery is connected with the refrigerating system and used for supplying power to the refrigerating system. The storage battery is a lithium air battery, the lithium air battery contains MnO2-RuO2 / C catalysts used for the lithium air battery, an active substance of the catalysts is MnO2-RuO2, a carrier of the catalysts is nanocarbon, and the catalysts comprise, by mass, 5%-20% of MnO2, 25%-55% of the nanocarbon and the balance RuO2. According to the refrigerator, the storage battery is arranged on a common refrigerator, so that the refrigerator can be moved in use. Meanwhile, due to the fact that the nanocarbon is wrapped, the contact probability of the nanocarbon and Li2O2 is reduced, and accordingly side reactions are reduced. Accordingly, energy efficiency of the battery and cycle performance of the battery are improved.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with battery power supply function and a method for preparing a battery catalyst. Background technique [0002] A refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. However, it is usually desired to bring some food or other objects that need to be frozen for a long time during family trips. A travelable refrigerator is the first choice for family trips. However, refrigerators in the prior art all use alternating current, which cannot meet daily needs. As a new type of high-efficiency green and environmentally friendly energy, lithium-air batteries have ultra-high specific capacity, energy density as high as 11140wh / ...
