A highly conductive 3D current collector that is dendritic, lightweight, and robust is synthesized for binder-free electrodes in lithium-ion batteries. It has excellent chemical/electrochemical stability in a wide voltage window (0-5 V) and robust mechanical behavior even after 600 cycles of compression. When active materials are grown in situ on the as-obtained current collector, the resulting cycling stability and rate capability far exceed those of conventional electrodes and other 3D current collectors.
