| Abstract: | The preparation of cobalt ferrite nanocrystals by coprecipitation method using spent lithium-ion batteries dissolved in H2SO4 was studied . The suitable coprecipitation pH value is 10.0. The effects of calcining temperature on the structure and morphology of products were studied by XRD, IR and TEM. The results show that the particle average size increases with the increasing of the calcined temperatures. The suitable calcined temperature is 700 ℃ and the crystallite of cobalt ferrites is 32.7 nm. |
| Keywords: | non-metallic inorganic material cobalt ferrite lithium-ion batteries coprecipitation |
