Monoclinic beta-AgVO3 nanoribbons with thickness of 10-20 nm, width of 80-100 nm and length of several hundred micrometers have been successfully prepared by a water evaporation method at 100 degrees C for 6 h without using any template and organic surfactant. A possible evolution mechanism from alpha-AgVO3 nanorods to beta-AgVO3 nanoribbons is proposed. The AgVO3 nanostructures are demonstrated as promising cathode materials in lithium ion batteries. The as-prepared beta-AgVO3 nanoribbons show improved electrochemical performance in comparison with alpha-AgVO3 nanorods due to the ultrafine morphology and thermodynamic stable crystal structure yielding a discharge capacity of 355 mA h g(-1) at a current density of 30 mA g(-1). It can still remain 32% of its initial discharge capacity after 20 cycles.
