Description
Technical Field
The invention relates to the technical field of battery recovery, in particular to disassembly and recovery equipment for a waste lithium battery pack.
Background
The lithium battery is a primary battery using lithium metal or lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution, unlike a lithium ion battery, which is a rechargeable battery, and a lithium ion polymer battery. The inventor of lithium batteries was edison. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. Therefore, lithium batteries have not been used for a long time. With the development of microelectronic technology at the end of the twentieth century, miniaturized devices are increasing, and high requirements are made on power supplies. The lithium battery has then entered a large-scale practical stage.
Lithium batteries generally have two shapes: cylindrical and square. The battery is internally in a spiral winding structure and is formed by spacing a polyethylene film isolating material which is very fine and has strong permeability between a positive electrode and a negative electrode. The positive electrode comprises a current collector consisting of lithium cobaltate (or lithium nickel cobalt manganese oxide, lithium manganate, lithium iron phosphate and the like) and an aluminum foil. The negative electrode is composed of a current collector composed of a graphitized carbon material and a copper foil. The battery is filled with organic electrolyte solution.
Lithium ion batteries have the advantages of high energy, long service life, low pollution and the like, and are widely used in various fields such as collection, computers, electric bicycles, electric automobiles, national defense and the like. Especially in the recent years, the explosive growth of electric automobiles and the associated large-scale power lithium battery market have the greatly increased demand and rejection of lithium batteries. The waste lithium ion batteries contain a large amount of available resources, such as valuable metals like iron, copper, aluminum, etc., and if the waste lithium batteries are improperly recovered, the waste lithium batteries can cause great resource waste and environmental pollution. Substances such as anode and cathode materials and electrolyte solutions of the lithium ion battery have great influence on the environment and human health. Therefore, if the waste lithium ion battery is treated by a common garbage treatment method (including landfill, incineration, composting and the like), metals such as cobalt, nickel, lithium, manganese and the like, inorganic compounds and organic compounds in the waste lithium ion battery can cause serious pollution to the atmosphere, water and soil, and the waste lithium ion battery has great harm. If the substances in the waste lithium ion battery enter the environment, heavy metal nickel, cobalt and arsenic pollution, fluorine pollution, organic matter pollution, dust and acid-base pollution can be caused. The electrolyte and its transformation products of waste lithium ion battery, such as LiPF6, LiCF3SO3, HF, P2O5, etc., solvent and its decomposition and hydrolysis products, such as DME, EMC, methanol, formic acid, etc., are all toxic and harmful substances, which can cause personal injury and even death.
In the prior art, the recycling of waste lithium batteries is just started, and the existing method for disassembling the waste lithium batteries in the recycling process has great limitation; the mode of disassembling of current old and useless lithium cell is manual disassembling usually, and prior art generally is artifical disassembling, utilizes the hammering breakage, and the in-process is disassembled in the manual work, and risk such as electrolyte is revealed and heavy metal diffusion easily appears, has electrolyte corrosion people's hand or inhales potential safety hazards such as gas harm health, and the manual work is disassembled and is taken a lot of work hard, inefficiency.
