Silk could be new 'green' material for next-generation batteries
The researchers found a way to process natural silk to create carbon-based nanosheets that could potentially be used in energy storage devices. Their material stores five times more lithium than graphite can — a capacity that is critical to improving battery performance. It also worked for over 10,000 cycles with only a 9 percent loss in stability . The researchers successfully incorporated their material in prototype batteries and supercapacitors in a one-step method that could easily be scaled up, the researchers note.
