This invention relates to the field of lithium battery material recycling technology, specifically to a method for recycling and utilizing cathode materials from retired lithium iron phosphate batteries. The recycled retired lithium iron phosphate battery cathode materials are crushed, and the fragments are soaked in a solvent with stirring. After filtration, the filter residue is repeatedly washed with deionized water and dried to obtain coarse powder of the recycled cathode material. The coarse powder is subjected to ICP testing, and lithium, iron, phosphorus, grinding aids, and anhydrous ethanol are added for wet ball milling. After ball milling, the powder is dried to obtain a precursor. The precursor is then sintered under a nitrogen atmosphere to obtain the lithium iron phosphate cathode material. This method for recycling retired lithium iron phosphate battery cathode materials is simple, environmentally friendly, and economically efficient. The recycled cathode material meets the requirements for use in the battery industry.

The utility model discloses an air conditioner, including panel subassembly and air deflector subassembly, panel subassembly includes panel part and buffer, and panel part has the air outlet edge, and the air outlet edge participates in the definition of the air outlet of air conditioner, and the buffer is wrapped at least part of the air outlet edge, and the air deflector subassembly is movably arranged at the air outlet, to open and close the air outlet and / or adjust the air outlet direction, and the buffer is arranged apart from the air outlet edge and the air deflector subassembly. Therefore, the buffer can realize the soft contact between panel part and air deflector subassembly, and improves the grinding problem between panel part and air deflector subassembly.
