Companies have been trying to figure out how to use carbon nanotubes in electronics. Batteries may be the answer, say researchers at Rensselaer Polytechnic Institute.
The device is a piece of paper infused with carbon nanotubes and a salt, which serves as an electrolyte. Because it stores energy and conducts it, the device can act like a battery.
A number of corporate labs and universities have come up with flexible batteries in the past. Power Paper from Israel makes a flexible battery printed on polymers that relies on zinc as an electrolyte. It sells it to the cosmetics industry. Japan … Read more
