| titleOfInvention | Lithium ion battery cathode material ferrous silicate/silicon dioxide/carbon and preparation method thereof |
| abstract | The invention discloses a lithium ion battery cathode material ferrous silicate/silicon dioxide/carbon and a preparation method thereof, belonging to the technical field of new materials and electrochemistry. The lithium ion battery cathode material is a three-layer composite material with a hollow structure, wherein the inner core is ferrous silicate, the middle layer is silicon dioxide, and the outermost coating layer is organic pyrolytic carbon. The preparation method comprises the preparation of ferroferric oxide nano particles, a silicon dioxide coating process, a carbon coating process and an acid etching ferroferric oxide removing process. Compared with the prior art, the hollow structure in the prepared material particle plays a good role in inhibiting the volume expansion of the material in the charge and discharge process, and is beneficial to improving the structural stability of the particle and the electrochemical performance of the electrode. The cathode material prepared by the method has excellent cycling stability, the first reversible specific capacity is more than 600mAh/g, and the capacity is hardly attenuated after 140 cycles. |
