摘要：

Highly conductive and hybridized microtubes relying on strain-released ultrathin Ti/Ge bilayer nanomembranes are reported. These hybrid multilayer microtubes show a remarkably enhanced reversible capacity up to 1495 mA h g(-1) with a high first-cycle Coulombic efficiency of 85%, and demonstrate an excellent capacity of approximate to 930 mA h g(-1) after 100 cycles.
