摘要：
Nanoporous NiO/V2O5 hybrid film has been successfully prepared by combining chemical bath deposition (CBD) and electrochemical deposition methods. The electrochemical and optical properties of the hybrid film were investigated by cyclic voltammetry (CV), amperometric i-t, UV-vis spectroscopy and colorimetry analysis. Compared with single V2O5 electrochromic film, the NiO/V2O5 hybrid electrochromic film reveals reasonably good cyclic stability, better transmittance modulation (35% at 776 nm) and higher coloration efficiency (30.6 C-1 cm(2) at 776 nm). The noticeably improved electrochromic properties are mainly attributed to the introduction of NiO polycrystal substrate with nanoflake-like structure, which helps strengthen the structural stability of V2O5 film and improve the performance of Li+ ions intercalation/deintercalation.
