The rise in sea level and atmospheric carbon emissions has spawned numerous researches on high-efficiency renewable energy sources. Solar energy and wind energy are among the best. Researchers at the University of Buffalo have developed a "fluorescent dye" called BODIPY. BODIPY is an abbreviation for "boron-dipyrromethene". It contains two unusual chemical properties that make it a "flow storage battery" (storing electrons and participating in electron transfer). One candidate.
Dr. Kosswattaarachchi holds a bottle of BODIPY super dye.
The significance of this discovery is that next-generation batteries need to handle these two aspects well (storing and releasing energy) before they can be used in large-scale power grids.
Research team leader Dr. Timothy Cook and thesis Anjula M. Kosswattaarachchi said: "BODIPY can also be used as a sensor to identify proteins and it can perform this function well."

Cook said: "With the increasing global dependence on alternative energy, we will face a big problem - how to store energy, especially in the night after the sun sets, or when the wind is no longer blowing, these energy sources are Intermittent, so we need batteries to store enough energy to power thousands of households."
This study blended PM 567 and acetonitrile solvents to create the fuel solution needed for the experiment.
Redox flow batteries are expected to solve this problem because their energy storage tanks can be easily scaled up to store large amounts of energy without exponentially increasing costs (especially compared to other systems based on lithium-ion batteries).
The current situation is that although liquid batteries have a relatively safe and cost-effective advantage, lithium-ion batteries still hold the position of market dominance.
The future is expected to supply super dyes for homes or cars.
To test the performance of the BODIPY-based battery, the team dissolved PM 567, an energy-based BODIPY dye, in acetonitrile solvent and then continued its hundreds of cycles of charge and discharge. It was found that the compound was not available throughout the entire cycle. There is a recession (this is very different from many other chemical materials).
Given that BODIPY has the same chemical properties, it is expected to develop more energy-storage dyes in the future. Based on the test results, the researchers predict that the BODIPY battery can produce a voltage of 2.3 volts.
The team’s findings have been published in the recently published journal ChemsusChem.
