AbstractNew V2O5 nanofilm electrodes without binder and conductive agents were fabricated by sintering the V2O5 film precursor at 300℃ on stainless steel substrates, which were coated from CTAB-containing V2O5 sol gel electrolyte by electrodeposition. X-Ray diffr
Other Abstract以含有CTAB的V2O5溶胶为电解液,采用电沉积法在不锈钢基体上沉积V2O5薄膜前体,经300℃烧结处理后制备了无黏结剂和导电剂的V2O5纳米薄膜电极。XRD测试表明该方法制备的V2O5薄膜是含水相的V2O5·n H2O,与未添加CTAB制备的薄膜相比,其层间距明显变大。FESEM和AFM测试发现CTAB辅助电沉积制备的V2O5薄膜具有粗糙多孔的表面形貌;XPS测试表明CTAB辅助电沉积制备的V2O5薄膜中含有更多的低价钒离子(V4+)。电化学测试发现该方法制备的V2O5薄膜具有优异的嵌/脱Na
