Paper batteries are a thing, who knew?
Respect to the guy on YouTube who just showed me how to make paper batteries, because my mind is now whirling with ideas about powering all kinds of things with them. It's left me wondering if they could help power gaming mice, but turns out that's a bit of a long shot.
You'll be surprised to learn that actually bashing one of these lightweight babies out isn't as difficult as it might sound. Rob simply followed the steps laid out by Alexandre Poulin et al. in their paper about theseRobert says the design is"based on a number of inks." There's a Cathode ink, an Anode ink, and a current collector ink, which together make a battery.
The Cathode even includes a material called Shellac—something you may have heard any of your manicured friends talking about in the context of getting their nails done—which works as a binder for the rest of the materials involved. It's kept flexible and prevented from drying out with Polyethylene glycol , and Ethanol is used to mix it all up, with Graphite being the main ingredient.
Those kind of calculations are a bit beyond us, but essentially it might be a bit difficult to fully power a gaming mouse with even a couple of these.
