• CaV 6 O 16 ·3H 2 O paper was prepared by hydrothermal method combined with cutting and drying process. • CaV 6 O 16 ·3H 2 O paper can be directly applied as a cathode for LIBs. • The self-standing CaV 6 O 16 ·3H 2 O paper electrode shows good electrochemical performance. CaV 6 O 16 ·3H 2 O three-dimensional (3D) tubular structure has been constructed by a simple hydrothermal method without using any surfactants or additives. The tubular structure is composed of ultralong CaV 6 O 16 ·3H 2 O nanobelts with good tailorability. By simply cutting and drying the 3D tubular structure, a CaV 6 O 16 ·3H 2 O paper has been successfully prepared. Electrochemical performance of the CaV 6 O 16 ·3H 2 O paper as the self-standing cathode for lithium-ion batteries (LIBs) was investigated for the first time. It delivers an initial discharge capacity of 463.9 mAh g−1 at 50 mA g−1 and maintains at 162.3 mAh g−1 after 50 cycles. This work provides the possibility for designing high-performance, long service life and lightweight LIBs for implantable medical devices. [ABSTRACT FROM AUTHOR]
