1. A negative electrode for a rechargeable lithium battery, comprising an assembly of non-sheet-shaped graphite particles, at least one silicon-based particle in a region formed between the non-sheet-shaped graphite particles and at least one sheet-shaped graphite powder particle between the non-sheet-shaped graphite particles contacting at least one non-sheet-shaped graphite particle and at least one silicon-based particle,
wherein a size of the at least one silicon particle is smaller than a length of the longest axis of the at least one sheet-shaped graphite powder particle. |
