<p>Provided is a lithium ion battery cathode material, comprising a material capable of being alloyed with lithium, a chemically bonded organic group, and a carbon material for cladding the material capable of being alloyed with lithium; and the carbon material is chemically bonded to the material capable of being alloyed with lithium via the organic group. Also provided is a preparation method of the lithium ion battery cathode material. The cathode material not only alleviates the dramatic volume expansion and shrinkage of the material capable of being alloyed with lithium, and the introduced carbon material helps to improve the conductivity of the whole material; moreover the cathode material also ensures the overall stability of the cathode material, and reduces the probability of network disconnection during electronic transmission, thus further improving the electrochemical performance of the cathode material.</p> |
