Abstract
The invention discloses a dry-type recycling method of a scraped aluminum-plastic film lithium iron phosphate battery. The dry-type recycling method comprises the following steps: 1) adding waste batteries into a conducting solution; completely discharging the batteries to be 0V; circularly cooling the conducting solution and keeping the temperature at 20 DEG C to 35 DEG C; 2) taking out the batteries and mechanically crushing the batteries; vacuumizing powder at 50 DEG C for 2h; enabling volatile matters including electrolyte and the like to enter a sealed pipeline through an exhausting hole of a vacuum pump, wherein ice water with the temperature of 3 DEG C to 5 DEG C flows outside the sealed pipeline; volatilizing the matters into liquid under the common effect of pressure and temperature and enabling the liquid to flow into a liquid storage tank for storing; 3) carrying out ultrasonic vibration on the powder and carrying out multi-grade cyclone sorting; separating according to material densities to obtain copper foil fragments, aluminum foil fragments, diaphragm fragments, lithium iron phosphate powder, graphite negative electrode powder and carbon powder respectively.
