Scientists at Stanford have found a way to produce bendable, lightweight batteries and supercapacitors using ink, paper, carbon nanotubes, and silver nanowires. The nanotubes and nanowires are mixed with ink and painted onto a piece of regular printer paper, which is then dried in an oven. The end result is thin, low-cost, and very flexible, just like your sister.
The paper supercapacitor may last through 40,000 charge-discharge cycles – at least an order of magnitude more than lithium batteries. [...] Cui had previously created nanomaterial energy storage devices using plastics. His new research shows that a paper battery is more durable because the ink adheres more strongly to paper. [...] What’s more, you can crumple or fold the paper battery, or even soak it in acidic or basic solutions, and the performance does not degrade. “We just haven’t tested what happens when you burn it,” he said. [...]
Cui predicts the biggest impact may be in large-scale storage of electricity on the distribution grid. Excess electricity generated at night, for example, could be saved for peak-use periods during the day. Wind farms and solar energy systems also may require storage. [Stanford]
I’m totally going to paint all six sides of a room with this stuff and pretend I’m James Woods’s's’s wife in the Quitters, Inc. part of Cat’s Eye.
