Rice University researchers have created spray-on battery paint, creating the potential for new gadget form factors.
One of the primary factors holding back the development of truly next-generation devices is battery technology. Yes, the lithium-ion power modules that energize most of our current flock of gadgets are fairly small and reliable. But they still take up a relatively large amount of space in our devices, and often dictate the form factor to a certain degree. Fortunately, scientists at Rice University in Texas have developed an interesting solution: spray-on batteries.
Neelam Singh, one of the Rice researchers involved in the project, says they will work to reduce the size of the paint needed to hold a meaningful charge, and hope to make their creation more user friendly. Singh tells New Scientist that he hopes to one day pair the spray-on battery with paintable solar cells, to create the next generation of home electrical systems. When exactly such a thing will be possible, well, we’ll just have to be patient.
