The outer shell of the lithium-ion battery is aluminum-plastic film shell, stainless steel or nickel-plated steel shell and plastic shell, etc. There are different models such as square and cylindrical. The internal of the small lithium-ion battery is a winding structure, and the power battery uses more Is the laminated structure. Lithium-ion batteries are composed of positive electrode, negative electrode, electrolyte, separator, casing, etc., and the composition of the positive and negative electrodes and electrolyte of this battery is not fixed. For example, the positive electrode can be lithium cobalt oxide, lithium manganate, and ternary materials. For materials such as lithium iron phosphate, the negative electrode can be graphite, alloy material, or lithium titanate. The diversity of composition reserves a lot of space for battery design, but it brings difficulties to recycling. The treatment and disposal of waste lithium-ion batteries is not only conducive to resource recycling, but also reduces environmental hazards caused by waste batteries, and has greater economic value, but improper disposal and disposal can also bring certain environmental risks.

Lithium Battery Recycling Machine

(3) The recovery and reuse of the main metal components in the battery and the electrolyte. So far, according to the different separation methods of battery active materials and current collectors, waste lithium battery recycling technologies can be divided into high-temperature calcination methods, solvent immersion methods, and mechanical and physical separation methods.

Starting from the full life cycle of lithium-ion batteries, encourage the development of low-consumption, high-energy, and low-polluting battery products and production processes, actively promote low-pollution production processes and equipment, and control pollutants from the source. On the other hand, strengthen the research and development of waste lithium ion battery treatment and disposal technology, and actively introduce SUNY GROUP environmental protection's mature waste battery treatment technology. For different battery systems of Li Co O2, ternary materials and Li Fe PO4, different treatment and disposal processes are adopted, which is beneficial to improve the recycling efficiency and reduce the recycling cost.
