11. Battery recycling
When the equipment or internal equipment reaches the end of its service life, it cannot be disposed of together with domestic waste. Some internal components can be recycled, and some components will cause environmental pollution.
11.1 Recovery process and steps of cathode materials
Aluminum foil as collector is amphoteric metal. Firstly, it is dissolved in NaOH alkali solution to make aluminum enter the solution in the form of NaAlO2. After filtration, the filtrate is neutralized with sulfuric acid solution and precipitated to obtain Al (OH)3. When the pH value is above 9.0, most of the aluminum precipitates, and the obtained Al (OH)3 can reach the level of chemical purity after analysis. The filter residue is dissolved with sulfuric acid and hydrogen peroxide, so that lithium iron phosphate enters the solution in the form of Fe2 (SO4) 3 and Li2SO4, and is separated from carbon black and carbon coated on the surface of lithium iron phosphate. After filtration and separation, the pH value of the filtrate is adjusted with NaOH and ammonia water. First, iron is precipitated with Fe (OH) 3, and the remaining solution is precipitated with saturated Na2CO3 solution at 90 . Since FePO4 is slightly dissolved in nitric acid, the filter residue is dissolved with nitric acid and hydrogen peroxide, which directly precipitates FePO4, separates impurities such as carbon black from acid solution, leaches Fe (OH) 3 from filter residue respectively, and precipitates Li2CO3 with saturated Na2CO3 solution at 90 .
48

11.2 Recovery of anode materials
The recovery process of anode materials is relatively simple. After the separation of anode plates, the purity of copper can be more than 99%, which can be used for further refining electrolytic copper.
11.3 List of recycling equipment
Recovery of diaphragm The diaphragm material is mainly harmless, and has no recycling value. List of recycling equipment Automatic dismantling machine, pulverizes, wet gold pool, etc.
