Tiivistelmä väitöstutkimuksesta:
In order to leave a healthy world to the upcoming generations, there is an urgent need to reduce the consumption of fossils fuels and switch to renewable energy sources. The use of solar and wind as clean energy sources requires the utilization of storage systems, like batteries, that can balance their intermittent generation. For that purpose, large-scale and cost-effective energy storage systems are required. We believe that the flow battery technology can be the answer for this issue. This dissertation explores flow batteries using alternative materials and introduces a monitoring system that enables an insight into the battery operation.
During my investigations, I studied the use of organic compounds as the active materials for flow battery applications. We think that organic molecules can offer a sustainable solution: if synthetized from renewable sources with easy procedures, these materials could solve the scalability and cost limitations. Additionally, with the proper molecular design, they can provide improvements in the battery performance. During these years, in a highly cooperative research work, we studied materials derived from vitamin-B6, called pyridoxals, and we modified well-known structures, denominated viologens, to improve desired key properties. Furthermore, we successfully introduced a new family of molecules, azoniafluorenones, which enable to build-up flow batteries with high-energy density. Finally, we also developed a measurement system that allows a deep monitoring of the battery operation with high reliability. This system provides very useful information to predict the cause of problems that lead to lifetime reduction and energy losses. These investigations are a step forward for the deployment of flow batteries to accelerate the transition to a more sustainable society.
