The cathode foil is composed of foam nickel (conductive material) and cathode chemical raw materials, while the anode foil is made up of steel strips and anode chemical raw materials. In simple terms, the chemical raw materials are tightly bonded to the foam nickel (steel strip) through a casting process, forming the cathode foil (anode foil). The cathode foil typically refers to high-potential electrode sheets containing active substances that undergo reduction reactions during discharge.

The recycling and processing technology for positive electrode sheets consists of the following processes:

1. Spent lithium-ion battery cathode material is conveyed to a shredder, where it is shredded to 15-25 mesh.

2. Material processed through a shredder is then conveyed to the analyzer.

3. The analytical machine separates the crushed material through air classification, separating out metal materials and lithium cobalt oxide powder.

4. The separated lithium cobalt oxide powder is conveyed to the aggregate collector by an induced draft fan.

5. Waste gases from the aggregate equipment are purified through a pulse filter before being discharged, and the metal materials sorted by the analyzer are then screened through a grading sieve. The grading sieve further separates the metal materials, separating lithium cobalt oxide powder and the metallic portion.

6. Lithium cobalt oxide powder from the grading screen is drawn into the aggregate collector via an induced draft fan from the first outlet. Aluminum powder filtered from the grading screen is collected directly from the third outlet. Other materials filtered from the grading screen enter the air classification separator via the second outlet. The air classification separator further grades and separates these materials, separating metallic aluminum and lithium cobalt oxide powder. The separated metallic aluminum is recovered and collected, while the separated lithium cobalt oxide powder is drawn into the aggregate collector by the induced draft fan. At this point, the non-metallic lithium cobalt oxide powder and metallic aluminum powder in the cathode sheet are successfully separated.

Key Considerations for Anode and Cathode Sheets:

1. Inspect for burrs or unevenness on the blade edge, and be mindful of blade usage precautions during operation.

2. Do not use the same blade for cutting positive and negative electrodes.

3. Continuously inspect the quality of the film during the cutting process, segregate any substandard pieces, and ensure they are not mixed with the good ones.

4. After the pieces are cut, they are inspected and then transferred to the next production process.

In the manufacturing process of battery packs, the following patterns are observed: the negative electrode determines the battery's stability and overcharge (discharge) performance, while the positive electrode determines the battery's capacity. If during the production process:

1. A lighter positive electrode can lead to a "low capacity" battery.

2. Overweight positive electrode sheets can cause leakage and bulging during the battery charging process, and in severe cases, may lead to battery explosion.

3. An underweight anode sheet can cause leakage and bulging during battery charging, and in severe cases, it may lead to an explosion.

4. Excessive weight on the negative electrode sheet can make it difficult to fit into the battery housing during assembly, leading to damage or short-circuiting of the positive and negative electrode sheets. Additionally, the heavier negative electrode sheet can result in wasted battery raw materials, reducing the material utilization rate of the battery. Therefore, whether the positive and negative electrode sheets are too light or too heavy, they can significantly affect the battery.

The composition of batteries consists of positive and negative electrodes, hence the materials attached to the electrodes significantly affect battery performance. Understanding the specific structure of batteries allows us to delve into the composition of the electrodes. The positive electrode is made up of sintered nickel (conductive material) and positive electrode chemical raw materials. The negative electrode is composed of steel strip and negative electrode chemical raw materials. In simple terms, the chemical raw materials are tightly bonded to the sintered nickel (steel strip) through a pulling slurry, forming the positive (negative) electrode. The positive electrode typically refers to electrodes with high potential that contain active substances undergoing reduction reactions during discharge.

Lithium-ion battery anode and cathode material recycling equipment is a processing and recovery line for various waste lithium-ion batteries, primarily through physical processing methods. It processes new energy lithium-ion batteries, cylindrical pouch cells, hard-case batteries, and steel-case batteries, converting them into anode and cathode materials. It separates valuable metals from the batteries. The cathode is formed by applying lithium cobalt oxide powder to both sides of an aluminum foil collector, while the anode structure is similar, consisting of carbon powder bonded to both sides of a copper foil collector. The processing technology consists of cathode and anode sheet processing techniques. The lithium-ion battery anode and cathode sheet processing system and technology includes a feeding platform, conveyor, shredder, analyzer, induced draft fan, collection device, pulse purifier, and grading sieve and separator.
