The composition of the battery consists of positive and negative electrodes, so the materials attached to the positive and negative electrodes directly affect the battery's performance. Understanding the specific structure of the battery, we then reverse-engineer the composition of the positive and negative electrodes.

The battery is composed of positive and negative electrodes, so the materials attached to the positive and negative electrodes directly affect the battery's performance. Understanding the specific structure of the battery, we can then look back at 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 up of steel strips and negative electrode chemical raw materials. Simply put, the chemical raw materials are tightly bonded to the sintered nickel (steel strip) through a slurry, forming the positive (negative) electrode. The positive electrode typically refers to an electrode with high potential that contains active substances undergoing a reduction reaction during discharge.

Lithium-ion battery anode and cathode material recovery equipment is a processing and recovery line for various waste lithium-ion batteries, mainly through physical processing methods. It is designed for the production line of treating new energy lithium-ion batteries, cylindrical soft packaging batteries, hard shell batteries, and steel shell batteries, to process anode and cathode materials, separating valuable metals from the battery. The cathode is formed by applying lithium cobalt oxide powder on both sides of an aluminum foil collector, while the anode structure is similar, composed of carbon powder bonded to copper foil collectors. The processing technology consists of two parts: cathode and anode sheet processing. The lithium-ion battery anode and cathode sheet processing system includes a feeding platform, conveyor, shredder, analyzer, induced draft fan, material collection device, pulse purifier, and a grading and sorting machine.

Key considerations for anodes and cathodes:

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

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

3. Continuously inspect the quality of the sheets during the cutting process, segregate any substandard ones, and ensure they are not mixed together.

4. After the pieces are cut, they are inspected and then transferred to the subsequent production processes.

The cathode sheet recycling process consists of the following steps:

1. Spent lithium-ion battery cathode material is conveyed to a crusher by a conveyor belt, where it is crushed to 15-25 mesh.

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

3. The analyzer separates the crushed material through air separation, selecting out metal materials and lithium cobalt oxide powder.

4. The separated lithium cobalt oxide powder is transported to the collection unit by an induced draft fan.

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

6. Lithium cobalt oxide powder from the grading sieve is channeled into the aggregate collector via an induced draft fan from the first output end. Aluminum powder filtered out by the sieve is collected directly from the third output end. Other materials filtered out are fed into the air classification machine through the second output end. The air classification machine further sorts the materials that have passed through the grading sieve, 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 sheet are successfully separated.
