Positive electrodes typically refer to high-potential electrode sheets containing active substances that undergo reduction reactions during discharge.
Key Precautions for Anode and Cathode Sheets:
1. Inspect for burrs and unevenness on the blade edge, and be mindful of the safety precautions when using the knife during operation.
2. Do not mix blades for positive and negative pole cuttings.
3. Continuously inspect the quality of the sheets during cutting, separating any substandard ones into separate categories; do not mix them together.
4. After the pieces are cut and inspected, they are then transferred to the subsequent production processes.

Lithium-ion battery anode and cathode material recycling equipment is a processing and recovery line for various waste lithium-ion batteries, mainly through physical processing methods. It processes new energy lithium-ion batteries, cylindrical pouch cells, hard shell batteries, and steel shell 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.

During the assembly 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 the battery is produced during the process:
1. A positively charged sheet that is too light can lead to "low capacity" in the battery.
2. Excessive positive electrode weight can lead to leakage and bulging during battery charging, and in severe cases, may cause the battery to explode.
3. If the negative electrode sheet is too light, it can cause leakage and bulging during the battery charging process, and in severe cases, it may lead to an explosion.
4. If the cathode sheets are too heavy, it can affect the battery's fit in the casing during assembly, leading to damage or short-circuiting of the cathode and anode sheets. Additionally, the excess weight of the cathode sheets can result in wasted battery raw materials, reducing the material utilization rate of the battery. Therefore, both underweight and overweight cathode sheets can significantly impact the battery.

The battery is composed of positive and negative electrodes, so the material used for the electrodes directly affects the battery's performance. Understanding the specific structure of the battery, we can then delve into the composition of the positive and negative electrodes. The positive electrode is made up of sintered nickel (a conductor) and positive electrode chemical raw materials. The negative electrode is made of steel strip and negative electrode chemical raw materials. Simply put, the chemical raw materials are tightly connected to the sintered nickel (steel strip) through a slurry, forming the positive (negative) electrode. The positive electrode typically refers to a high-potential electrode containing active substances that undergo a reduction reaction during discharge.

The recycling and processing technology for anode sheets consists of the following steps:
1. Waste lithium-ion battery cathode material is transported to a shredder via a conveyor belt and shredded to 15-25 mesh.
2. Material processed by the crushing machine is conveyed to the analyzer.
3. The analyser separates the crushed material through air separation, sorting out metal materials and lithium cobalt oxide powder.
4. The separated lithium cobalt oxide powder is conveyed to the collection unit by an induced draft fan.
5. The waste gas in the aggregate unit is purified through a pulse filter before being discharged, and the metal materials sorted by the analyser are then screened through a grading sieve. The grading sieve further separates the metal materials, separating out lithium cobalt oxide powder and the metallic fraction.
6. Lithium cobalt oxide powder from the grading screen is channeled into the aggregate collector via an induced draft fan from the first output end. Aluminum powder, separated by the grading screen, is directly collected from the third output end. Other materials separated by the grading screen enter the air classification machine via the second output end. The air classification machine further sorts 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 gathered into the aggregate collector via the induced draft fan. Thus, the non-metallic lithium cobalt oxide powder and metallic aluminum powder in the cathode sheets are successfully separated.
