University of British Columbia researchers have found a new way to make state-of-the-art materials for energy storage using a cheap lamp from the hardware store.

The researchers wanted to find a better way to make coatings that can be painted onto surfaces to conduct electricity or convert electricity into hydrogen fuels. Typically these coatings are made in more extreme conditions with expensive tools and materials. But the researchers developed a technique that allows them to use a consumer grade heat lamp to get the same results. Once the solution was painted onto a surface and heated up, it transformed into a catalytic .

These coatings can be used in a range of technologies, such as flexible electronic devices or to convert electricity into hydrogen fuels. The discovery, published today in the new open access journal Science Advances, could have implications for consumer electronics and .

"Solar farms and wind turbines don't provide a constant supply of ," says study co-author Curtis Berlinguette, an associate professor in UBC's Departments of Chemistry and Chemical and Biological Engineering. "Storing produced during times of low demand as hydrogen fuels enables that to be used later during peaks of higher demand. The catalyst coatings we can now produce more easily could help make this process cheaper and more efficient."

The researcher's new technique may also help reduce the fabrication costs of making catalyst-coated electrodes in commercial applications, such as electrolyzers.

"The technique is scalable and amenable to large-scale manufacturing," says Danielle Salvatore, a chemical engineering graduate student and the paper's lead author.

"We can create these materials on any surface without an expensive precursor," says Berlinguette, explaining that these findings build on earlier work of using more expensive UV light to create catalytic films .

A tiny, high-capacity electric battery could spawn applications we never consider.

1) Electrically heated clothing. Currently, we have to heat entire buildings to keep the occupants comfortable. However, in some cases, it might be possible for people to wear heated vests, heated pants, heated gloves, heated shoes, or heated caps--at a great overall savings in energy. Buildings that are cold are also less likely to be fungus-infected and to need frequent disinfection.

2) Misplaced items in warehouses, businesses, homes, etc are an aggravation and a financial drain. It would be very nice if every sofa in a furniture warehouse, every extra purse in a woman's home, and every tool in a repair shop communicated wirelessly and automatically with the building's central computer. Users could quickly find misplaced items and inventory supplies. The house computer could communicate with other local establishments to arrange possible buying/selling of surplus items.
