C@MoS2@PPy sandwich-like nanotube arrays as an ultrastable and high-rate flexible anode for Li/Na-ion batteries

A Flexible and freestanding C@MoS2@PPy sandwich-like nanotube arrays on steel foil have been fabricated by a simple template-based approach. Due to the inner conductive carbon submicron tube arrays (CSTAs) skeleton and outer PPy coating, the resultant hybrid anode owns robust Li-ion and Na-ion electrochemical storage performance.421
