SnO 2 –carbon nanotube (CNT) composite sheets are synthesized using poly(vinylpyrrolidone) to uniformly load a monolayer of SnO 2 nanoparticles onto the surfaces of CNTs and CNT bundles within cross‐stacked CNT sheets. When they are used as high‐capacity (over 850 mA h g –1 ) and binder‐free anodes in rechargeable lithium‐ion batteries, they exhibit good cycle performance, as shown in the lower portion of the figure.
