A multilayer graphene/GeO2 tubular nanoarchitecture by a strain-driven method shows simultaneously a high reversible capacity of 919 mAh g−1 at 0.1 C after 100 cycles, a remarkable cycling performance of over 100% capacity retention after 700 cycles with a very high capacity of 821 mAh g−1 at 1 C, and superior rate capability.
