With the development of economy, people have higher and higher demands for material life and spirituality, and more and more intelligent devices are entering the people's homes. The sweeping robot, also called the lazy sweeper, is an intelligent household appliance that can automatically vacuum the ground. Because it can detect factors such as room size, furniture placement, and floor cleanliness, and rely on built-in programs to formulate a reasonable cleaning route, it has a certain degree of intelligence, so it is called a robot. With the introduction of intelligent sweeping robots into thousands of households, people's requirements for sweeping robot batteries have gradually increased. The focus is on energy saving and environmental protection, long service life, safety and stability, and suitable for environmental temperatures in various regions.
