Description

Technical Field

[0002] As national policies strongly support the popularization of electric vehicles, power batteries, as energy storage devices for electric vehicles, have developed rapidly. However, due to the limitation of service life, power batteries need to be properly disposed and recycled after the end of their life cycle to improve the recycling of resources and reduce environmental pollution.

[0003] After disassembling retired batteries, the active components of the electrode need to be effectively separated from the current collector. Lithium iron phosphate pole pieces mainly use organic binders to make the lithium iron phosphate material adhere to the current collector. The existing process usually removes the binder by calcination, but the separation rate of the formed sheet-like lithium iron phosphate material and the current collector is still low. Therefore, it is necessary to develop a lithium iron phosphate pole piece de-powdering device to achieve efficient de-powdering of lithium iron phosphate pole pieces. Utility Model Content
