"The paper, published in Nature Scientific Reports, explains that by breaking down the different components of a battery the electrodes, separator, electrolyte and current collectors and rendering them into liquid form, we could revolutionize the way we power our devices. Rather than being tied to fixed shapes and sizes, batteries could one day take on practically any form, and be applied almost anywhere.
The technology, it says, would enable, widespread renewable energy capture, storage and utilization.
Lithium-ion batteries are made by tightly rolling up the various battery components in layers before encasing them in rectangular or cylindrical packaging. The engineers, from Rice University in Texas, devised their own unique version of a multilayer battery by painting these individual battery components (two current collectors, a cathode, an anode and a polymer separator) on to select surfaces in layers. These layers included paints made from lithium cobalt oxide (a positive electrode), lithium titanium oxide (a negative electrode) and conductive single-walled nanotubes (a current collector). The special polymer paint blend helped achieve superior conductivity by forming the micro-porous layer required in a lithium battery."
Personally, I`m a bit shocked and a bit excited with how far scientists have come. I mean spray-on batteries? How cool is that!

If the so called "Spray-on Batteries" make their way into stores would you pick up a can? Leave a comments and let me know!
