Ca2Ge7O16 NS/CNT composites on Ni foam have been successfully fabricated for long cycling lithium-ion batteries.
Flexible CNT@SnS2 sponges with controllable mass ratios and various morphologies of loaded SnS2 from tubular nanosheaths to nanosheets have been fabricated and can be used as free-standing and binder-free electrodes applied in lithium-ion batteries.
