The electrochemical performance of a thick Ge film (ca. 1020 nm) is dramatically improved by adopting vertically aligned carbon nanotube (VACNT) arrays as a 3D current collector. The VACNT-supported thick Ge film exhibits high reversible specific capacity (1352 mAh g(-1) ), and excellent capacity retention (97.2% after 100 cycles) and rate capability (843 mAh g(-1) at 10 C).

Surface-engineered tape-casting (SETC) is a facile and scalable preparation method to fabricate freestanding, flexible and foldable MWCNT and MWCNT-composite sheets.

A hierarchical three dimensional carbon nanowire arrays on carbon cloth is developed as an efficient flexible nanostructure current collector for TiO 2 based anodes. This unique electrode exhibits not only ~300 times higher mass
