Adopting a nano- and micro-structuring approach to fully unleashing the genuine potential of electrode active material benefits in-depth understandings and research progress toward higher energy density electrochemical energy storage devices at all technology readiness levels. Due to various challenging issues, especially limited stability, nano- and micro-structured (NMS) electrodes undergo fast electrochemical performance degradation. The emerging NMS scaffold design is a pivotal aspect of many electrodes as it endows them with both robustness and electrochemical performance enhancement, even though it only occupies complementary and facilitating components for the main mechanism. However, extensive efforts are urgently needed toward optimizing the stereoscopic geometrical design of NMS scaffolds to minimize the volume ratio and maximize their functionality to fulfill the ever-increasing dependency and desire for energy power source supplies. This review will aim at highlighting these NMS scaffold design strategies, summarizing their corresponding strengths and challenges, and thereby outlining the potential solutions to resolve these challenges, design principles, and key perspectives for future research in this field. Therefore, this review will be one of the earliest reviews from this viewpoint.
采用纳米和微观结构化方法来充分释放电极活性材料的真正潜力,有助于在所有技术成熟度水平上对更高能量密度的电化学储能装置有更深入的理解和研究进展。由于各种具有挑战性的问题,特别是稳定性有限,纳米和微观结构化(NMS)电极的电化学性能会快速退化。新兴的NMS支架设计是许多电极的关键方面,因为它赋予电极稳健性和电化学性能提升,尽管它在主要机制中仅占互补和促进性组件。然而,迫切需要做出大量努力来优化NMS支架的立体几何设计,以最小化体积比并最大化其功能,以满足对能源电源供应不断增长的依赖和需求。本综述旨在突出这些NMS支架设计策略,总结其相应的优势和挑战,从而概述解决这些挑战的潜在解决方案、设计原则以及该领域未来研究的关键观点。因此,本综述将是从这个角度进行的最早的综述之一。
