Abstract

CaV6O16·3H2O spong-like and tube-like three-dimensional (3D) structures were constructed by a simple hydrothermal method. The 3D structures composed of superlong CaV6O16·3H2O nanobelts have good tailorability. CaV6O16·3H2O papers with different thickness can be obtained by simply pressing (cutting) and drying the 3D structures. The electrochemical performances of the obtained CaV6O16·3H2O paper as the self-standing cathode for lithium-ion batteries (LIBs) were 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 provide the possibility for designing high-performance cathode for LIBs.
