Problems solved by technology

However, according to the statistics of China Automotive Technology Research and Development Center, the recovery rate of scrap batteries in my country is less than 2%, and waste lithium-ion batteries contain a large amount of available resources, such as valuable metals such as aluminum and copper, graphite, and positive electrode materials. It also contains nickel, cobalt, manganese, lithium and other heavy metal materials and electrolytes. Once waste batteries cannot be effectively disposed of, it will not only cause waste of resources, but also cause serious pollution to the environment.
[0005] The current power battery is divided into lithium iron phosphate battery and ternary battery. In the lithium iron phosphate battery, the lithium iron phosphate material is coated on the surface of the positive aluminum foil. Decomposition reaction occurs, leading to failure of positive electrode material
[0006] In the ternary battery, the ternary material is coated on the surface of the positive aluminum foil. After the internal short circuit of the power battery, when the temperature rises to about 300°C, the ternary material will decompose and release part of the oxygen. With this temperature rise, it will exceed the combustion time of the electrolyte. , the oxygen produced by decomposition participates in combustion, and a gas explosion will occur in a limited space, resulting in failure of the positive electrode material and damage or combustion of components inside the battery
The above methods have the following disadvantages: 1. Environmental pollution, fire and explosion are prone to occur when waste batteries are discharged; Pyrolysis treatment eliminates the diaphragm and increases the discharge of pollutants; 3. The accuracy of cutting and separating waste batteries is difficult to control, which is easy to cause fires. At the same time, it is only suitable for square batteries, not for other batteries, and has strong limitations.

Description

technical field [0001] The invention relates to the technical field of crushing lithium batteries and lithium battery modules, in particular to a system for crushing charged lithium batteries and lithium battery modules. Background technique [0002] Lithium batteries are widely used in daily life due to their advantages of high energy density, large working voltage, no memory effect and long cycle life, such as cameras, mobile phones, notebook computers and portable measuring instruments and other electronic products. The preferred light and high-energy power source for electric vehicles. However, after lithium batteries are scrapped, they often bring certain harm to the environment and human health, and cause waste of resources; the recycling and harmless recycling of waste lithium batteries is imminent. [0003] With the development of society and technology, the application of lithium batteries is becoming more and more common, especially power lithium batteries and lit...
