What are the recycling methods of waste phosphate?lithium ion golf cart batteries wholesaler

　　① By crushing the abandoned iron phosphate battery to obtain a positive film,

　　② Under the conditions of an inert atmosphere or restoring atmosphere, the thermal tablets are carried out to carbonize the adhesive.

　　③ The active substance and aluminum foil are effectively separated under the action of ultrasonic shock separation.

　　④ Add an appropriate amount of raw materials to the obtained iconic iron phosphate recycling material to obtain the required lithium, iron, and phosphorus,

　　⑤ Then synthesize new lithium iron phosphate according to the high temperature and solid phase.

　　a. Use two methods of organic solvent NMP and alkaline solution to the active substances obtained by being separated from the positive film soaking;

　　b. In the air atmosphere, heated it at 200 ° C for 4h to remove the adhesive and carbon in it, and add lithium, iron source and phosphorus source compounds to the lithium iron phosphate powder obtained;

　　c. Optimize the lithium, iron, and phosphate molby added, and then add sucrose to it, and then in the hydrogen hydrogen mixed gas environment, d. Boil the mixed powder at 700 ° C constant temperature 煅 9h, and get lithium iron phosphate material after burning.

　　e. The test results of physical characteristics and electrochemical performance show that the synthetic iron phosphate particles are uniform and complete in structure. The first discharge ratio of the battery made of lithium iron phosphate is greater than 120mAh/g. The capacity maintenance rate is still above 95%, indicating that the new synthetic iron phosphate has met the requirements of preparing battery electrode materials.
