项目摘要

Stationary energy storage solutions for the grid are becoming increasingly important to store energy from intermittent renewable sources and to meet peak energy consumptioSn demands. Redox flow batteries are attractive for microgrid and solar farm applications. Currently, techniques such as pumped hydro-electric plants are used for storing renewables at this scale, however batteries have advantages in terms of high round trip efficiencies, low maintenance costs and tuneable energy and power outputs. Redox flow batteries are particularly interesting for these large-scale storage applications. Integrating RFBs with solar cells into a single device that can be recharged directly by light presents a possible way of overcoming current prohibitively high costs associated with current systems, which require additional expensive power electronics. These systems are however still poorly understood and substantial work is needed both on the chemistry side to make the electrolytes more stable and on the materials engineering side to fabricate efficient and stable photoelectrodes and scale-up their manufacture. In this PhD project, we will focus on the latter and leverage techniques developed by the nanotech community to fabricate structured carbon electrode structures using a combination of bottom-up and top-down methods and to decorate these with nano photocatalysts.

电网的固定储能解决方案对于存储来自间歇性可再生能源的能源并满足峰值能源消耗需求变得越来越重要。氧化还原液流电池对于微电网和太阳能发电场应用具有吸引力。目前，抽水蓄能电站等技术用于存储如此规模的可再生能源，但电池在高往返效率、低维护成本以及可调节的能源和电力输出方面具有优势。氧化还原液流电池对于这些大规模存储应用特别有趣。将 RFB 与太阳能电池集成到可直接通过光充电的单个设备中，提供了一种克服当前系统相关成本过高的可能方法，该系统需要额外昂贵的电力电子设备。然而，人们对这些系统仍然知之甚少，在化学方面需要做大量的工作来使电解质更加稳定，在材料工程方面也需要做大量的工作来制造高效和稳定的光电极并扩大其生产规模。在这个博士项目中，我们将重点关注后者，并利用纳米技术界开发的技术，结合自下而上和自上而下的方法来制造结构化碳电极结构，并用纳米光催化剂装饰它们。
