ELECTROACTIVE MATERIAL AND ITS USE IN ANODES FOR LITHIUM-ION CELLS |
| 摘要 |
The present invention relates to a novel electroactive material which comprises a graphitic carbon phase C and a (semi)metal phase and/or a (semimetal) oxide phase (MOx phase) and also to the use of the electroactive material in anodes for lithium ion cells. The invention further relates to a process for producing such materials. The electroactive material comprises: a) a carbon phase C; b) at least one MOx phase, where M is a metal or semimetal, x is from 0 to <k/2, where k is the maximum valence of the metal or semimetal. In the electroactive material of the invention, the carbon phase C and the MOx phase form essentially co-continuous phase domains, with the average distance between two neighboring domains of identical phases being not more than 10 nm, in particular not more than 5 nm and especially not more than 2 nm. |
