One step preparation of a high performance Ge–C nanocomposite anode for lithium ion batteries by tandem plasma reactions

We employ a tandem plasma reaction method to prepare ultrafine Ge nanoparticles embedded in a carbon matrix in one step. The obtained Ge-C composite exhibits very high lithium storage capacity (980 mA h g(-1)) and excellent cycling performance (less than 2% capacity loss in 100 cycles).
