COMPOSITE POWDER FOR USE IN AN ANODE OF A LITHIUM ION BATTERY, METHOD FOR MANUFACTURING A COMPOSITE POWDER AND LITHIUM ION BATTERY

摘要

Composite powder for use as electrochemically active material in an anode of a lithium ion battery, whereby the particles of the composite powder comprise a carbon-based matrix material and silicon particles embedded in this matrix material, whereby the silicon particles and the matrix material have an interface, characterized in that at this interface there are Si-C chemical bonds present.
