With the development of economy, people have higher and higher requirements for material and spiritual life, and more and more smart devices are entering people’s homes. The sweeping robot, also called the lazy sweeper, is a smart household appliance that can automatically vacuum. 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, which is why it is called a robot. As intelligent sweeping robots enter thousands of households, people's requirements for sweeping robot batteries are gradually increasing. They focus on energy saving and environmental protection, have long service life, safety and stability, and are suitable for environmental temperatures in different regions.
