The invention discloses the discharging method and discharging agent for recycling waste batteries. It immerse the waste batteries with coke powder to form a discharging circuit and to remove the residual power off the waste batteries before destruction of the batteries. The discharging performance varied with resistivity of the coke powder, and can be measured by watching the temperature and/or the temperature change trend. The resistivity depends on the ratio of carbon composition of the coke powder and the contact quality between the coke powder and the waste batteries, and the pressure on coke powder can adjust the contact quality. Therefore, the method is able to adjust the discharging performance by adjusting the pressure to meets the discharging requirements of efficiency and safety.
A discharging method for recycling waste batteries, comprising:
A coke powder used as a discharging agent for recycling waste batteries, comprising a carbon composition 65-99 wt %, an ash composition 0.5-18%, a volatile composition 0.5-3%, and a water composition 0.5-13%, wherein the c coke powder has a resistivity 0.08-0.35 Ω·cm, a specific heat capacity about 0.78-1.5 kj/(kg·K), a thermal conductivity 2.09-2.91 kj/(m·h·K), and a particle size 0.1-0.6 mm.
