چکیده انگلیسی
In present work, microrod structured La2O3 thin films are grown on to the stainless steel substrate using a binder free single step hydrothermal method. The structural, morphological and active surface area properties of La2O3 thin film are studied by scanning electron microscope (SEM), X-ray diffraction (XRD), contact angle, X-ray photoelectron spectroscopy (XPS), Fourier transformation spectroscopy (FT-IR), and Brunauer-Emmer-Teller (BET) techniques. The La2O3 thin film electrode showed the maximum specific capacitance of 250 F gâ1 at a scan rate of 5 mV sâ1 with an excellent cycling performance (81%) up to 1000 cycles. The La2O3 thin film electrode shows maximum specific energy and specific power of 80 Wh kgâ1 and 1.5 kW kgâ1, respectively. The symmetric solid state supercapacitor devices (SSSD) with La2O3 thin film have been fabricated using gel electrolyte (PVA-LiClO4).
