高纵横比多材料电极的可扩展制造对于先进的能量存储和转换系统非常重要。此类技术通常依赖于基于溶液的加工方法，其中活性材料分散在胶体墨水中。迄今为止，油墨配方主要侧重于宏观尺度的特定工艺优化（即粘度和表面/界面张力），并主要根据经验进行优化。因此，还需要了解纳米和介观尺度的相互作用，以及如何设计它们来控制与电化学系统中的性能、耐久性和材料利用率相关的宏观特性和结构。
Scalable manufacturing of high-aspect-ratio multi-material electrodes are important for advanced energy storage and conversion systems. Such technologies often rely on solution-based processing methods where the active material is dispersed in a colloidal ink. To date, ink formulation has primarily focused on macro-scale process-specific optimization (i.e. viscosity and surface/interfacial tension), and been optimized mainly empirically. Thus, there is a further need to understand nano-and mesoscale interactions and how they can be engineered for controlled macroscale properties and structures related to performance, durability, and material utilization in electrochemical systems.
