Lithium battery refers to a battery containing lithium in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Li-ion batteries do not contain metallic lithium and are rechargeable;

Because dry batteries are made of carbon poles, manganese dioxide powder, and zinc shells. So if you don't recycle the used dry batteries, just throw away the batteries at will, and the used batteries will be buried underground together with other domestic waste. After being buried in the ground, the divalent manganese and zinc in the waste battery will change into soluble manganese bicarbonate and zinc bicarbonate respectively in the presence of oxygen deficiency and carbon dioxide, and dissolve in the groundwater that people drink daily. Once people drink it, people will have strange symptoms of madness. Manganese changes are at the root of this madness.

At the same time, a button battery can pollute 600 tons of water, which is equivalent to a person's lifetime drinking water; while a No. 1 battery is buried underground, which can make one square meter of land lose its use value, and the land requires It took nearly a hundred years to degrade this battery, so the recycling of used batteries is urgent;

However, for some rural areas, due to the imperfection of waste sorting facilities and the weak awareness of waste sorting and environmental protection among residents, the used up batteries are directly discarded, or directly put into the trash can without sorting, thus As a result, used waste batteries directly coexist with the living environment of residents, which will not only pollute the living environment of residents, but also affect the health of residents.

Based on the overall implementation of the present invention, when the battery passes through the buffer layer 36, the battery will roll down onto the collecting plate 21. Since the collecting plate 21 is initially flush with the bottom of the buffer layer 36, the battery passing through the buffer layer 36 can Rolling directly onto the collecting plate 21 can reduce the degree of impact on the battery during this process, thereby preventing the battery from being damaged. At the same time, because the collecting plate 21 is in a balanced state under the action of the spring, when a battery rolls down to the collecting plate 21 When going up, the weight on the upper surface of the collecting plate 21 increases at this time, thereby causing the collecting plate 21 to move down for a certain distance. As the weight on the collecting plate 21 gradually increases, the collecting plate 21 gradually moves down. The gradual increase of battery weight on the plate 21 controls the distance that the collecting plate 21 moves down, which can increase the content of the collecting battery in the collecting plate 21, and can also prevent the distance between the collecting plate 21 and the buffer layer 36 from increasing instantaneously, resulting in The battery rolled down on the buffer layer 36 is hit;

At the same time, since the balls 23 are provided on the surface of the collecting plate 21, when the battery rolls down onto the collecting plate 21, the battery will move towards the door 13 under the action of the balls 23. During this process, the batteries can be prevented from accumulating near the buffer layer. 36, thereby reducing the collection plate 21 to collect the battery content.

During specific implementation, the rollers 35 and the balls 23 arranged on the collection plate 21 are more densely arranged in the storage bin 3 in the button battery collection bin 2 and the battery plate battery collection bin 2;
