dc.description.abstractFilms of electrochromic Ni oxide, with thickness in the similar to 100-1000-nm range, were prepared by reactive advanced gas deposition (AGD) and, for comparison, also by reactive DC magnetron sputtering (MS). Voltammetric cycling was performed in an electrolyte of lithium perchlorate in propylene carbonate in the voltage range 2.0-4.1 V vs Li/Li+, and concurrent optical transmittance modulation was studied at a wavelength of 530 nm. For the thickest films, the optical modulation range was as large as similar to 54% and the maximum transmittance was similar to 82% for deposition by AGD, whereas the corresponding numbers were similar to 45% and similar to 87% for MS. Rutherford backscattering spectrometry together with measurements of film thickness demonstrated that the porosity of 400-500-nm-thick films made by AGD and MS were similar to 84% and similar to 45%, respectively. The charge exchange per mass unit was as high as 48-67 C g(-1) for samples made by AGD. The corresponding number was much lower for MS, namely 13-18 C g(-1). These results lend convincing support to the view that the electrochromism of Ni-oxide-based films in Li-ion-conducting electrolytes is dominated by surface effects.
