“…In contrast, organic cathode materials composed of lightweight elements (such as C, H, O, N, and S) have inherent advantages such as resource renewability, environmental friendliness, and structural diversity. [86][87][88][89][90] Therefore, organic cathode materials are considered as promising cathode candidates in aqueous Zn-organic batteries (ZOBs). The research on organic cathode materials for aqueous ZOBs can be traced back to polyaniline (PANI) in 1985.…”

Aqueous zinc‐ion batteries (ZIBs) have emerged as the most promising candidate for large‐scale energy storage due to their inherent safety, environmental friendliness, and cost‐effectiveness. Simultaneously, the utilization of organic electrode materials with renewable resources, environmental compatibility, and diverse structures has sparked a surge in research and development of aqueous Zn‐organic batteries (ZOBs). A comprehensive review is warranted to systematically present recent advancements in design principles, synthesis techniques, energy storage mechanisms, and zinc‐ion storage performance of organic cathodes. In this review article, we initially summarize the energy storage mechanisms employed by aqueous ZOBs. Subsequently, we categorize organic cathode materials into small‐molecule compounds and high‐molecular polymers respectively. Novel polymer materials such as conjugated polymers (CPs), conjugated microporous polymers (CMPs), and covalent organic frameworks (COFs) are highlighted with an overview of molecular design strategies and structural optimization based on organic cathode materials aimed at enhancing the performance of aqueous ZOBs. Finally, we discuss the challenges faced by aqueous ZOBs along with future prospects to offer insights into their practical applications.

The physical microtopography, in an effective and stable manner, can powerfully confer biomaterials with enhanced osteoconduction for the repair of critical‐sized bone defects. However, the realization of the osteoconductive microtopography within a 3D porous scaffold is still unmet. Herein, this work presents a stone‐cottage‐inspired printing strategy to build microsphere patterned scaffolds with a tunable microtopography for accelerated bone regeneration. The customized composite inks of poly (lactic‐co‐glycolic acid) microspheres as “Stone” and alginate hydrogels as “Mortar” endow the fibers of as‐printed scaffolds with a stable and tunable groove‐ridge microstructure. Owing to this microtopography, microsphere patterned scaffolds significantly promote cell recruitment, immune response, angiogenesis, and osteogenesis. Meanwhile, compared to 55 and 85 µm, 25 µm width of groove‐ridge microstructure displays the most osteoconduction for repair of critical bone defects. Mechanistically, while cells prefer to adhere to microstructure with a bigger width and higher modulus in the early phase, this microstructure should also act as a barrier for cell growth and its smaller width is more beneficial for cell communication and differentiation in the later phase. Overall, it provides a robust strategy to fabricate the osteoconductive microtopography within a 3D scaffold, broadening the manipulation of physical morphology in tissue engineering.

Nickel‐Zinc (Ni‐Zn) batteries offer an interesting alternative for the expanding electrochemical energy storage industry due to their high‐power density, low cost, and environmental friendliness. However, significant reliability challenges such as capacity fading, self‐discharge, thermal instability, and electrode degradation detract from their competitiveness in the market, hindering their widespread adoption. This study thoroughly examines the degradation mechanisms and approaches to improve the reliability of Ni‐Zn batteries: Starting with their basic chemistry, operating principles, and degradation pathways, strategies for improvement are explored including material modification, electrolyte optimization, cell design approaches, and thermal management techniques. Advanced characterization methods for data collection and reliability assessment are discussed, including electrochemical, structural, spectroscopic, and in situ techniques which are noted for their ability to identify key areas of concern for this cell chemistry. We further consider emerging trends such as novel materials, hybridization with other energy technologies, and the challenges of large‐scale implementation, emphasizing the need for standardized reliability testing protocols. Opportunities for the integration of advanced sensing, such as fiber Bragg grating (FBG) sensors for real‐time monitoring and anomaly detection, along with machine learning (ML) and prognostics and health management of Ni‐Zn batteries are highlighted, as these open the door to future research directions. This comprehensive review should serve as a resource for researchers, engineers, and industry experts aiming to advance and commercialize dependable, high‐performing Ni‐Zn battery technology for a sustainable energy future. image
