Spray-on batteries can be painted-on just about anywhere!
Remember how flexible lithium-batteries grabbed our fancy before? Well, we’ve now stumbled across something more to dream about. Developed by the students of the Rice University, this spray-on lithium-ion battery can be applied just about anywhere and could very well be used to power small devices. All you need to do is spray the different layers of the battery one on top of the other on a flat surface and hook on an energy source to the same and voila! You’ve got yourself a tiny battery with enough juice to power up smaller devices!
