One of the greatest challenges nanotechnology is facing today, is the lack of processes to organise nanoparticles into well-controlled structures at scale. Similar to how advanced lithography has enabled the mass production of transistors, we need to develop methods to reliably and cost effectively assemble nanomaterials at scale. If successful, such processes can potentially revolutionise how we filter water, fabricate biomedical implants, harvest and store energy, to name a few. This PhD project will follow a methodical approach to develop such a process for large area coating of battery electrodes using Roll-to-Roll. We will use a methodologic approach to optimise material morphology from the bottom-up, starting with nanoscale optimisation of nanomaterial interfaces, microscale pore structures and large scale coating. This PhD project has an interesting new angle at addressing this challenge by combining R2R processing with Microfluidics and self-assembly for the first time. The improved morphological control over the electrode architecture that will be attained by this project will allow for improved ion and electron transport in the electrode, which is of key importance to improve for instance the charging times required in electrical vehicles, which to date remain a major bottleneck for a wider adoption of electrical vehicles. Figure 2 shows an example of how advanced nanomaterials will be synthesised (Figures 2a-c), how they will be coated on R2R using microfluidic coating heads (Figure 2d), and the resulting self-assembled materials (Figure 2E). Finally, the fabrication process pursued in this project is not only useful for advancing battery electrodes, but also for many other applications with high societal impact, including water filtration and catalysis.

纳米技术今天面临的最大挑战之一是缺乏将纳米颗粒组织成规模可控结构的过程。与先进的光刻技术如何实现晶体管的大规模生产类似，我们需要开发出可靠且具有成本效益的方法来大规模组装纳米材料。如果成功的话，这些过程可能会彻底改变我们过滤水，制造生物医学植入物，收集和储存能量的方式。这个博士项目将遵循一种有条不紊的方法来开发这样一种使用卷对卷的电池电极大面积涂层工艺。我们将使用一种方法学的方法来优化材料形态从自下而上，从纳米材料界面，微米级孔结构和大规模涂层的纳米级优化开始。这个博士项目有一个有趣的新角度，通过将R2 R处理与微流体和自组装首次结合起来来应对这一挑战。该项目将实现对电极结构的改进的形态控制，这将允许改进电极中的离子和电子传输，这对于改善例如电动车辆中所需的充电时间至关重要，迄今为止，这仍然是电动车辆更广泛采用的主要瓶颈。图2显示了如何合成先进纳米材料（图2a-c），如何使用微流体涂覆头将其涂覆在R2 R上（图2d）以及所得自组装材料（图2 E）的示例。最后，该项目所追求的制造工艺不仅可用于推进电池电极，还可用于许多其他具有高度社会影响的应用，包括水过滤和催化。
