PEDOT-PSS coated nanostructured Ge anodes were prepared for lithium-ion batteries. The obtained binder-free electrodes show excellent electrochemical performance. The representative anode exhibits a reversible capacity of 640mAhg−1 after 1000 cycles at a current density of 2Ag−1, which is much better than the nanostructured Ge anodes without PEDOT–PSS coating. The significantly enhanced cycle performance can be attributed to that the PEDOT-PSS coating highly facilitates the structural integrity of the electrode.
