Description

Technical Field

[0001] The utility model relates to the technical field of positive electrode sheet recycling, in particular to a positive electrode sheet recycling reaction device for lithium iron phosphate batteries. Background Art

[0002] The positive electrode sheet usually refers to an electrode sheet with a high potential that contains active substances that undergo a reduction reaction during discharge. The electrode of a battery is composed of a current collector and active substances, a binder, a conductive agent, etc. Electrode sheets can be divided into different electrode sheets according to different standards, for example: self-adhesive electrode sheets, if divided according to the material, can be divided into 1. PET self-adhesive electrode sheets 2. Silicone self-adhesive electrode sheets, 3. Silicone self-adhesive electrode sheets 4. Other button self-adhesive electrode sheets; silicone electrode sheets can be divided into water-absorbing electrode sheets, heating electrode sheets, conductive electrode sheets, etc. according to their uses. In addition to electrode sheets, there are also electrode wires and related physical therapy products. The positive electrode, a physical concept, refers to the end of the power supply with a higher potential (potential). It is also used in electrochemistry. In electrochemistry, the usage habits of physics are followed. In a primary cell, the device is a power source, and the electrode where the current flows out has a higher potential and is the positive electrode. This electrode plays a reducing role, that is, the ions or molecules gain electrons. In an electrolytic cell, the device is an electrical appliance, and the electrode connected to the positive electrode of the power source plays an oxidizing role, that is, the ions or molecules lose electrons, depending on the connected power source, which is different from a primary cell.

[0003] At present, the recycling method of waste lithium iron phosphate batteries is usually scraper grinding. The positive electrode of the lithium iron phosphate battery can be grinded by a grinding device to separate the lithium iron phosphate material from the aluminum foil and grind it into fine particles of lithium iron phosphate recycled material. However, a large amount of dust will be generated in the scraper grinding process, which is not conducive to collection and will also pollute the environment. Utility Model Content
