Abstract
A silicon-carbon composite. In order to improve the cycle stability of a lithium cell equipped therewith, the silicon-carbon composite is produced by a condensation reaction of silicon particles surface-modified with a first condensation-capable group and carbon particles surface-modified with a second condensation-capable group, the silicon particles being covalently bonded to the carbon particles via the condensation reaction product of the first condensation-capable group and the second condensation-capable group. In addition, a method for the production thereof and to an electrode, an electrode material, and a lithium cell is described.
Claims15
A method, comprising:
- forming a silicon-carbon composite by reacting, in a condensation reaction, silicon particles that are surface-modified with a first condensation-capable group and carbon particles that are surface-modified with a second condensation-capable group capable of condensing with the first condensation-capable group;
- wherein the silicon particles are covalently bonded to the carbon particles via a product of the condensation reaction in which the first condensation-capable group reacts with the second condensation-capable group.
