| titleOfInvention | Preparation method of carbon/metal sulfide/carbon three-dimensional porous array composite electrode material for lithium ion battery |
| abstract | The invention relates to a preparation method of a carbon/metal sulfide/carbon three-dimensional porous array composite electrode material for a lithium ion battery. The electrode material uses a carbon skeleton obtained by calcining bamboo as an array substrate, metal oxide active substances are loaded by adopting the processes of organification removal, acidification and the like, then the stability of the material is enhanced by glucose coating and carbonization treatment, and then the electrochemical performance is increased by modifying oxides into sulfides by adopting the processes of suction filtration, drying, ultrasonic treatment and hydrothermal vulcanization, so that the carbon/metal sulfide/carbon three-dimensional porous array composite electrode material for the lithium ion battery is finally obtained. The invention is environment-friendly, does not contain noble metal and heavy metal, is convenient and feasible, is beneficial to industrial large-scale production, and the prepared electrode material has excellent conductivity and stability, high charge-discharge specific capacity and electrochemical cycle performance, and has huge application potential in the field of lithium battery cathode materials. |
