通过SILAR法制备片状-棒状SrO薄膜用于超级电容器高效能量存储

The SrO thin films electrode was successfully synthesized using the Successive Ionic Layer Adsorption and Reaction (SILAR) technique, exhibiting a well-defined cubic crystalline structure with an average crystallite size of 18 nm, as confirmed through XRD analysis. The films demonstrated a flake-rod like morphology, which provided a high surface area and facilitated efficient ion diffusion, thereby enhancing their electrochemical performance. Electrochemical measurements revealed a specific capacitance ( Cs (cv) ) of 599.5 F/g at a sweep rate of 5 mV/s, coupled with outstanding cycling stability, retentive 83.4% of an initial capacitance after 6000 cycles. Additionally, the Ragone plot analysis indicated a good balance between energy density as well power density, underscoring a potential of SrO thin films electrode as a promising material for higher performance supercapacitors.
