At present, advocating environmental protection today, the new energy industry has been the world's more important industry. Plays a vital role is: power battery. In particular, new energy vehicles, power lithium batteries also have many advantageous features. But with the continuous development, but also incessantly renewed, so lithium battery recycling has become the environmental resource issues facing today, if the waste battery for casual disposal, it will cause a certain impact on the environment pollution, so from the recycling of resources, waste lithium battery recycling is also vital. If the lithium battery is not recycled, it will cause some harm to the environment as well as the economic value.
Power lithium batteries can be classified according to the different anode materials. Different lithium battery manufacturers use different materials, will be based on the actual situation of the enterprise to choose a more suitable material as the basic. Lithium battery is mainly composed of: positive and negative electrode, diaphragm, fluid collector, electrolyte and shell and other parts. In the lithium battery, the positive and negative electrode materials will have a great impact on the ecological environment. Take the lithium battery for vehicles.
Positive electrode materials: three elements of nickel, cobalt and manganese, lithium iron phosphate, lithium manganate and other materials.
Negative materials: carbon, artificial graphite, natural graphite, silicon-carbon alloy and lithium titanate materials, etc.
Diaphragm materials: polyolefin, mainly including polyethylene and polypropylene diaphragm
Electrolyte: carbonate solvent and lithium hexafluorophosphate electrolyte salt
Lithium battery recycling resources recycling.
Used lithium batteries contain: aluminum, copper, nickel, cobalt, manganese and many other precious metals, if its efficient recycling to promote sustainable development, used lithium battery recycling process contains three processes: pre-treatment, recycling, reuse. Pretreatment requires the first step of lithium battery discharge, disassembly and separation, this process mainly contains: short discharge, liquid nitrogen low-temperature perforation, etc.. Separation technology mainly includes: mechanical separation, heat treatment, organic solvent dissolution, etc. Recovery: the common mechanical-physical method, dry method, wet method recovery. Mechanical physical method is common is the use of lithium battery recycling equipment for recycling dismantling treatment, wet recycling: separation is through chemical solvent extraction leaching needs to be transferred to the decomposition of the metal in the positive activity of the dissolution solution, and finally in the extraction, precipitation, adsorption, and electrolysis of high-value metals for separation and recovery. Reuse: Through direct repair and regeneration, or electrode material synthesis technology, the main methods include: high-temperature solid-phase synthesis, sol-gel method, hydrothermal synthesis and electrodeposition regeneration method, etc.
