In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn\u2019t shining and the wind doesn\u2019t blow.<\/p>\n

One possibility is to use any excess solar- and wind-based energy to charge solutions of chemicals that can subsequently be stored for use when sunshine and wind are scarce. At that time, the chemical solutions of opposite charge can be pumped across solid electrodes, thus creating an electron exchange that provides power to the electrical grid.<\/p>\n

The key to this technology, called a redox flow battery, is finding chemicals that can not only \u201ccarry\u201d sufficient charge, but also be stored without degrading for long periods, thereby maximizing power generation and minimizing the costs of replenishing the system.<\/p>\n

University of Rochester researchers, working with colleagues at the University at Buffalo, believe they have found a promising compound that could transform the energy storage landscape.<\/p>\n

In a paper published in Chemical Science<\/em>,<\/a> an open access journal of the Royal Society of Chemistry, researchers in the lab of Ellen Matson, assistant professor of chemistry, describe modifying a metal-oxide cluster, which has promising electroactive properties, so that it is nearly twice as effective as the unmodified cluster for electrochemical energy storage in a redox flow battery.<\/p>\n

\u201cEnergy storage applications with polyoxometalates are pretty rare in the literature,\u201d says lead author Lauren VanGelder, a third-year PhD student in Matson\u2019s lab. \u201cThere are maybe one or two examples prior to ours, and they didn\u2019t really maximize the potential of these systems.\u201d<\/p>\n

\u201cThis is really an untapped area of molecular development,\u201d adds Matson.<\/p>\n

The cluster was first developed in the lab of German chemist Johann Spandl, and studied for its magnetic properties. Tests conducted by VanGelder showed that the compound could store charge in a redox flow battery, \u201cbut was not as stable as we had hoped.\u201d<\/p>\n

However, by making what Matson describes as \u201ca simple molecular modification\u201d\u2014 replacing the compound\u2019s methanol-derived methoxide groups with ethanol-based ethoxide ligands\u2014the team was able to expand the potential window during which the cluster was stable, doubling the amount of electrical energy that could be stored in the battery.<\/p>\n

Says Matson: \u201cWhat\u2019s really cool about this work is the way we can generate the ethoxide and methoxide clusters by using methanol and ethanol. Both of these reagents are inexpensive, readily available and safe to use. The metal and oxygen atoms that compose the remainder of the cluster are earth-abundant elements. The straightforward, efficient synthesis of this system is a totally new direction in charge-carrier development that, we believe, will set a new standard in the field.\u201d<\/p>\n

The electrochemical testing required for this study involved equipment and techniques not previously used in the Matson lab. Hence the collaboration with Timothy Cook, assistant professor of chemistry at the University of Buffalo, and Anjula Kosswattaarachchi, a fourth-year graduate student in the Cook lab. VanGelder visited the Cook lab for training on testing equipment, and in turn helped Kosswattaarachchi with synthesizing compounds.<\/p>\n

The two groups have applied for a National Science Foundation grant as part of an ongoing collaboration to further refine the clusters for use in commercial redox flow batteries.<\/p>\n

Matson stressed the \u201ccrucial role\u201d played by VanGelder, who conducted the initial testing and experiments on the clusters while Matson was on maternity leave. \u201cAs a third-year graduate student, she did an incredible job of starting this project. She\u2019s played an important role in driving this research effort in the lab,\u201d Matson says.<\/p>\n

A University Furth Fund<\/a> Award that Matson received last year enabled the lab to purchase electrochemical equipment needed for the study. Patrick Forrestal \u201919 of the Matson lab also contributed to the study.<\/p>\n","protected":false},"excerpt":{"rendered":"
