Abstract

<jats:title>Abstract</jats:title><jats:p>The modern research reported the simplest low–cost synthesis of Bismuth–Copper oxide (Bi<jats:sub>2</jats:sub>CuO<jats:sub>4</jats:sub>) with spruce–leaf–like morphology and its applications in supercapacitor devices. Bi (NO<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub> . 5H<jats:sub>2</jats:sub>O was used as a precursor during an electrodeposition (ED) method to create the spruce–leaf–like Bi<jats:sub>2</jats:sub>CuO<jats:sub>4</jats:sub> electrode. XRD, XPS, FE−SEM, EDX, and TEM were used to characterize the structures and morphologies of the synthesized materials, while CV, CP, and EIS were used to determine their electrochemical characteristics. The Bi<jats:sub>2</jats:sub>CuO<jats:sub>4</jats:sub> phase was confirmed by XRD patterns, and electrochemical testing demonstrated that the material had better rate capability and an SC of 431.2 F/g at a scan rate of 2 mV/s. After 5,000 cycles, it retained 81.4 % of its energy. Additionally, the maximum SC that was attained by the created asymmetric solid–state device ASSD (Bi<jats:sub>0.6 V</jats:sub>ǀǀ1 M PVA−KOHǀǀAC) was 73.7 F/g. The energy density was 55.3 Wh/Kg at a power density of 4570 W/Kg. The exceptional electrochemical performance of Bi<jats:sub>2</jats:sub>CuO<jats:sub>4</jats:sub> thin film electrodes recommends it has a promising material.</jats:p>
