| Abstract: | Recovery of Ni-Cd batteries was studied by a self-designed vacuum-aided recycling system under laboratory conditions. The impacts of temperature, pressure and time were studied respectively. The mechanism of vacuum thermal recycling was also discussed. The results show that , at constant pressure, the increase of temperature can improve the separation efficiency of cadmium. When the temperature is 1173 K, the cadmium can evaporate completely from the residue during 3 h at 10 Pa. The reduction of pressure in a certain range is effective to separate cadmium by vacuum distillation. Distillation time is a very important factor affecting separation of cadmium. |
