Method for recycling waste lithium ion battery positive electrode material by using reed biomass

The invention relates to a method for recycling a waste lithium ion battery positive electrode material by using reed biomass. The method comprises the following steps that heating, stirring and centrifuging are carried out by using biomass reeds and water as raw materials (the mass ratio of reed powder to water is 1: 4) to obtain green solvent reed juice; and 5-10 g of the reed juice and 0.025-0.1 g of the waste lithium ion battery positive electrode material are weighed, and the waste lithium ion battery positive electrode material is recycled under the conditions that the reaction temperature is 25-120 DEG C and the reaction time is 8-24 hours. The method for recycling the waste lithium ion battery positive electrode material by using the reed biomass is provided, and the method is green, low in cost, simple and convenient, and has a very high practical application value. 本发明涉及一种利用芦苇生物质回收废旧锂离子电池正极材料的方法，该方法以生物质芦苇与水为原料(芦苇粉末与水质量比为1∶4)加热搅拌并离心后得到绿色溶剂芦苇汁。称取芦苇汁5克～10克，废旧锂离子电池正极材料用量0.025克～0.1克，在反应温度为25摄氏度～120摄氏度、反应
