Battery life has always been a major obstacle to the development of electric vehicles. In Ningbo, Zhejiang, this “endurance spell†is being broken, and new research techniques are expected to solve the “mileage anxiety†of electric vehicles.
The reporter learned from the Ningbo Institute of Materials of the Chinese Academy of Sciences that the research team recently used graphene to develop a kilowatt-class aluminum air battery. The energy density is more than four times that of the current commercial lithium-ion battery. One kilogram of aluminum can make the electric car run 60. Kilometers, which doubles the life of electric vehicles, has an attractive market prospect in electric vehicle range extenders.

It is reported that the battery system has an energy density of 510Wh/kg, a capacity of 20kWh, and an output power of 1000W. Through the actual demonstration, the system can simultaneously power a TV, a computer, an electric fan and 10 60W lighting bulbs, which preliminarily verified the power generation capability of the aluminum air battery system.
Liu Zhaoping, director of the Zhejiang Provincial Key Laboratory of Graphene Application Research, said that if the battery is used in a new energy vehicle, the body can be light and the cruising range can be greatly improved. If used on a mobile phone charging treasure, the output power can be greatly improved. In addition, the traditional communication base station acid lead battery is replaced once every 3-4 years, while the aluminum air battery developed by Ningbo Materials has a storage time of about 15 years, and the battery life is much longer.
"It is the advantage of high energy density, low price, abundant resources, green pollution-free, long discharge life, etc. Aluminum air battery has attractive market prospects in communication base station backup power supply and electric vehicle range extender application." Liu Zhaoping said .

In recent years, the global research on metal-air batteries has not stopped, but its industrial development still faces many technical bottlenecks. For example, the electrode power density needs to be improved, and it is difficult to meet the high power output and low anode utilization.
The "industrial magic" of graphene has made a new breakthrough in this research. Xue Yejian, senior engineer of the Power Lithium Battery Engineering Laboratory of Ningbo Institute of Materials Science, Chinese Academy of Sciences, told reporters that they used graphene composite manganese-based oxide catalyst and new graphene-based high-efficiency air cathode to increase the power density of single cells by 25%, greatly improving the metal. Comprehensive performance of air batteries.
It is reported that the research team is actively designing and developing a 5kW high-power aluminum air battery system for communication base station backup power and electric vehicle range extender. In addition, Ningbo Materials Institute has invested 3 million yuan to purchase a non-standard production line - pilot test line, which is expected to be completed by the end of August. This production line can produce 35,000 cathodes of metal air batteries annually. The "super energy battery" can be mass-produced in the future.
