Abstract

The invention discloses a metal air battery which comprises an air electrode, a metal electrode, an electrolyte, a controller, a power amplifier and an ultrasonic generator. When a metal air battery of a vehicle is started, the controller receives a starting instruction through a bus and generates an electric signal with set frequency according to the starting instruction, the power amplifier amplifies the electric signal with the set frequency, the ultrasonic generator converts the amplified electric signal into an ultrasonic vibration signal, and attachments covering the metal electrode is separated by the electrolyte, so that the metal air battery is rapidly started. When the metal air battery of the vehicle is turned off, the controller receives a turning off instruction through the bus and controls stop of the ultrasonic generator through the power amplifier according to the turning off instruction, and the surface of the metal electrode can generate a compact attachment serving as an oxidation film, so that self-corrosion of the metal electrode can be avoided during stop.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a metal-air battery. Background technique [0002] The vehicle can reduce the pollution to the driving environment by the discharge form of the battery it carries, and has a significant effect on reducing the air pollution in the metropolis. Although it may not be able to reduce the final carbon dioxide emissions, the above effects are still very meaningful due to the unevenness of people's living conditions. At present, lithium-ion batteries widely used in vehicles have low energy density, and the cruising range of vehicles is low. Polymer lithium-ion batteries with high energy density may spontaneously ignite under high temperature and sunlight conditions. Therefore, the development of metal-air batteries with high energy density and safe use has become a promising solution. [0003] At present, metal-air batteries use metal zinc, aluminum, magnesium, etc. as the negative e...
