Recycle the production of batteries in the process of substandard batteries and corners, this part of the battery will be tested and sorted, the battery can be used in energy storage equipment or low-speed electric vehicles, and the end-of-life battery is harmlessly dismantled into regenerated battery materials. What metals and materials can be crushed and recycled by the waste lithium battery recycling equipment?
The positive electrode is generally lithium manganate or lithium cobaltate, lithium nickel cobalt manganate material, and the positive electrode powder will be sold to downstream metallurgical enterprises for purification after treatment by lithium battery recycling equipment.
The negative electrode is made of graphite, or carbon with a structure similar to graphite, and the conductive collector is made of electrolytic copper foil with a thickness of 7-15 microns. At present, graphite is the mainstream commercial lithium cathode material, its theoretical gram capacity is 372mAh/g, the better graphite cathode material on the market can reach 360mAh/g, and the gram capacity gradually tends to the limit value. Lithium battery recycling equipment can process and sell the anode material to downstream gold treatment enterprises and other graphite industries.
The conductive collector of the negative electrode of lithium battery uses copper foil, as the collector fluid of lithium battery, - the general thickness is usually between 7-20um. At present, new energy vehicles are equipped with copper foil thickness of 8-12μm, and the mass of copper foil of the whole vehicle reaches more than 10kg. The copper powder will be recycled as raw material for lithium battery and used in various copper products, so that the product can be recycled in a green sense.
The conductive collector of the positive electrode of the lithium battery uses aluminum foil, the positive electrode of the electric car lithium battery needs to use aluminum foil, and requires the car itself to be as light as possible, and aluminum is the preferred material for lightweight automotive parts, aluminum plays a vital role in the development of electric and hybrid vehicles. 2030 electric vehicle ownership will account for more than 30% of total ownership, the new energy vehicle industry for the aluminum The new energy vehicle industry has opened up a new application field for aluminum.
The Chinese new energy vehicle industry has opened up a new application area for aluminum. After the lithium battery recycling equipment, the aluminum foil in the lithium battery is separated in the form of aluminum powder, which is sold to downstream metallurgical enterprises and various aluminum products enterprises, truly achieving resource recycling without waste.
Diaphragm is one of the most critical internal structure of lithium batteries, its role is to separate the positive and negative electrodes to prevent the battery short circuit, as the electrolyte is an organic solvent system, so the need for organic solvent-resistant diaphragm material, generally using high-strength thin film diaphragm, lithium battery recycling equipment to obtain the diaphragm is used in a variety of plastic products.
Battery shell is divided into steel shell, aluminum shell, nickel-plated iron shell, aluminum-plastic film, battery cap. As the battery shell material types are not -, Will classify and collect all kinds of shells and sell them to different metallurgical enterprises and steel products enterprises.
