Spray-on batteries could turn any surface into energy

Battery technology is seeing some exciting developments at the moment; liquid solar cells and current-generating paint are both examples of inventions set to revolutionise the clunky AA mainstay. And now scientists have added something new to the mix: spray-on batteries.

Developed by researchers at Rice University, this new technology allows any surface to become a battery, which could have pretty big implications for traditional energy storage and solar power generation. More on the science of the creation here.

Lead author of the team’s report Neelam Singh said: “Spray painting is already an industrial process, so it will be very easy to incorporate this into industry. We really do consider this a paradigm changer.”

However, there are some drawbacks, namely the spray-paint’s sensitivity to moisture and oxygen given its toxic, flammable and corrosive properties. Eliminating these issues through further research could see the paint being used at a large scale in industrial environments.
