Problems solved by technology
At present, the commonly used method is to disassemble the equipment in each process and hand it over to the outsourcing supplier for cleaning, and the units that cannot be cleaned can be replaced directly
Therefore, this method not only makes the cost of equipment replacement and cleaning high, but also takes a long time, which seriously affects the production schedule.

The invention relates to the technical field of lithium ion batteries, and discloses a cleaning method for a lithium ion battery slurry conveying system. The leaning method is used for conducting typechange cleaning on the lithium ion battery slurry conveying system, and comprises the following steps that automatic feeding equipment is cleaned; a stirring cylinder, a transit cylinder and a glue making tank in a stirring system are cleaned; a slurry conveying pipeline in the stirring system is cleaned; and a temporary storage tank, a coating pipeline and a coating mold head in a coating systemare subjected to disassembling cleaning and are assembled after cleaning is completed. Through the method, parts of devices can be avoided being disassembled, the time for cleaning is saved, and thedevice type change cleaning cost is reduced.
Description
technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a cleaning method for a slurry delivery system of a lithium-ion battery. Background technique [0002] With the increase in the mileage requirements of electric vehicles, the demand for high-energy-density ternary lithium batteries is increasing. Correspondingly, the proportion of lithium iron phosphate batteries in the power battery market is gradually declining, which makes lithium battery companies Gradually increase the research and development efforts and production capacity of ternary lithium batteries. [0003] However, at present, due to its own safety issues and the recent continuous occurrence of battery pack fires, it has become the first choice of lithium battery companies to ensure the production capacity of ternary lithium batteries without blindly expanding production capacity. Among them, some lithium battery companies have begun to transform the or...
