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.

Abstract Exploring new carbon‐based electrode materials is quite necessary for enhancing capacitive deionization (CDI). Here, hollow mesoporous carbon spheres (HMCSs)/metal‐organic frameworks (MOFs) derived (NC(M)/HMCSs and NC(M)@HMCSs) are successfully prepared by interface‐coating space‐encapsulating design, respectively. The obtained NC(M)/HMCSs NC(M)@HMCSs possess a hierarchical nanoarchitecture with abundant nitrogen doping, high specific surface area, meso‐/microporous pores. These merits conducive to rapid ion diffusion charge transfer during the adsorption process. Compared NC(M)/HMCSs, exhibit superior electrochemical performance due their better utilization of internal space carbon, forming an interconnected 3D framework. In addition, introduction Ni ions more synergistic effect between ZIF(M)‐derived N‐doped shell compared other (Mn, Co, Cu ions). resultant Ni‐1‐800‐based CDI device exhibits excellent salt capacity (SAC, 37.82 mg g −1 ) good recyclability. This will provide direction MOF nanoparticle‐driven assembly strategy application CDI.

Abstract Adopting a nano- and micro-structuring approach to fully unleashing the genuine potential of electrode active material benefits in-depth understandings research progress toward higher energy density electrochemical storage devices at all technology readiness levels. Due various challenging issues, especially limited stability, micro-structured (NMS) electrodes undergo fast performance degradation. The emerging NMS scaffold design is pivotal aspect many as it endows them with both robustness enhancement, even though only occupies complementary facilitating components for main mechanism. However, extensive efforts are urgently needed optimizing stereoscopic geometrical scaffolds minimize volume ratio maximize their functionality fulfill ever-increasing dependency desire power source supplies. This review will aim highlighting these strategies, summarizing corresponding strengths challenges, thereby outlining solutions resolve principles, key perspectives future in this field. Therefore, be one earliest reviews from viewpoint.
