Article Abstract

3D printing (3DP) has emerged as a transformative technology for the fabrication of electrochemical energy storage devices (EESDs), offering unprecedented advantages in design freedom, shape conformality, and material versatility. Unlike previous reviews that narrowly focus on specific materials or device types, this review offers a comprehensive and integrative perspective on the role of 3DP across the full architecture of EESDs, including batteries, supercapacitors, and fuel cells. Recent advances are highlighted in ink formulation strategies tailored for electrochemical functionality, advanced printing techniques enabling microscale precision and structural complexity, and the integration of printed components into functional devices. In discussing future directions, particular emphasis is placed on artificial intelligence (AI)-guided hybrid 3DP approaches that enable the simultaneous use of multiple materials and printing methods within a single process, facilitating the creation of customizable, multifunctional, and shape-adaptable EESDs. By outlining key opportunities and ongoing challenges, this review aims to provide a comprehensive roadmap for the future development of 3D-printed electrochemical energy storage technologies.

Carbonized wood has great potential as a self-supported electrode for energy storage/conversion applications. However, developing efficient and economical bifunctional electrodes by customizing the surface structure remains a challenge. This study proposes a novel multifunctional electrode design strategy, using N/P co-doped carbonized wood (NPCW) as carriers and in situ grows copper nanoparticles (Cu NPs) as nucleation centers to induce vertical growth of CuCo-layered double hydroxid (LDH) nanosheets along the substrate.

A novel aggregation-induced emission (AIE) system with superior performance was successfully developed through local chemical modification from thiophene to thiophene sulfone. This approach, leveraging easily accessible tetraphenylthiophene precursors, dramatically enhances the photophysical properties in a simple oxidation step. Notably, the representative 2,3,4,5-tetraphenylthiophene sulfone (3c) demonstrates remarkable solid-state emission characteristics with a fluorescence quantum yield of 72% and an AIE factor of 240, substantially outperforming its thiophene analog.

The rapid development of liquid exfoliation technology has boosted fundamental research and applications of ultrathin two-dimensional (2D) materials. However, the small-sized exfoliated 2D materials with a high specific surface area may exhibit poor chemical stability. Understanding the stability of 2D crystals will be significant for their preservation and service and for the development of new stable phases via the spontaneous transition from unstable structures.

It is anticipated that wide-bandgap semiconductors (WBGSs) would be useful materials for energy production and storage. A well-synthesized, yet scarcely explored, diamond-like quaternary semiconductor LiZnGeS has been considered for this work. Herein, we have employed two well-known functionals GGA and mGGA within a framework of density functional theory (DFT).

Electronic capacitor films based on polymer matrices and inorganic nanofillers capable of storing more energy play a crucial role in advanced modern electrical industries and devices. Herein, a series of nanocomposite films composed of "core-shell-dot" BNNs-PDA@Ag hybrid structures with multiple breakdown strength enhancement mechanisms as fillers and methyl methacrylate--glycidyl methacrylate (MG) copolymers as matrices were successfully synthesized. The introduced 2D and wide-bandgap BNNs not only enhanced the breakdown strength by taking advantage of their excellent physical properties, but also further improved their energy storage properties both at ambient and elevated temperatures through the formation of deeper traps at the organic-inorganic interface.
