Abstract Developing efficient, lightweight, and durable all‐solid‐state supercapacitors is crucial for future energy storage systems. The study focuses on optimizing electrode materials to achieve high capacitance stability. This introduces a novel two‐step pyrolysis process synthesize activated carbon nanosheets from jute sticks (JAC), resulting in an optimized JAC‐2 material with yield (≈24%) specific surface area (≈2600 m 2 g −1 ). Furthermore, innovative situ synthesis approach employed hybrid nanocomposites (NiCoLDH‐1@JAC‐2) by integrating JAC nickel‐cobalt‐layered double hydroxide nanoflowers (NiCoLDH). These serve as positive the negative asymmetric (HSCs), exhibiting remarkable performance metrics. HSCs of 750 F , capacity 209 mAh (at 0.5 A ), density 100 Wh kg 250 W ) using PVA/KOH solid electrolyte, while maintaining outstanding cyclic Importantly, functional theory framework utilized validate experimental findings, underscoring potential this enhancing HSC enabling large‐scale production transition metal‐based layered hydroxides.
