We have developed kilowatt-grade aluminum air battery with energy density up to 510 Wh/Kg by means of graphene

The research team recently developed an aluminum air battery power generation system based on graphene air cathode with an energy density of 510 Wh/Kg(watt-hour per kilogram) and a capacity of 20 kilowatt-hours. The output power is 1000 watts. The actual demonstration shows that the battery system can simultaneously power a television, a computer, an electric fan, and 10 60-watt lighting bulbs, and the initial verification of the power generation and power supply capacity of the aluminum air battery system.

Graphene is a "fighter" in materials. China has developed kilowatt-grade aluminum air batteries using graphene. This is a major breakthrough in the field of new energy and new materials.

Xueyejian, senior engineer of Ningbo Institute of Industrial Technology of the Chinese Academy of Sciences, told reporters that the core material of aluminum air batteries is a cathode catalyst doped with graphene. The product uses an aluminum plate as an anode, and an air cathode inserted into a graphen-based composite catalyst is placed in a container containing an electrolyte. Aluminum reacts with air to generate electricity.

The aluminum air battery currently has 22 national patents and can be used in electric vehicles, communication base stations and other fields. Because graphene-based composite oxides are used as catalysts, the dispersion of the material can reduce the internal consumption of the battery itself, and the aluminum air battery is several times more powerful than the normal Gaochu battery, greatly improving the endurance.

If used on the new source car, it can reduce the battery volume, make the body light, greatly increase the mileage; If it is used on mobile phone charging, it can greatly increase the output power; However, if the communication base station uses this type of battery, the advantage is also obvious. At present, the communication base station in China uses lead-acid batteries, which are replaced every two or three years. It is very difficult for some remote areas to update, but the service life of aluminum air batteries is 15 ~ 20 years. This challenge can be addressed to a large extent.

The reporter also learned that in the future, aluminum air batteries can also be used on horse lights and navigation lights, because when people in the sea encounter an emergency lack of electricity, they can use seawater and connect wires to generate electricity. This can also make the journey safer and more convenient for some donkeys.

According to Dr. Liuzhaoping, a researcher at the Zhejiang Provincial Key Laboratory of Graphene Applied Research, the experimental production line for experimental production of aluminum air battery cathode using graphen-based composite oxide as a catalyst has been completed, and it can be mass-produced and marketed in the future.
