Recent research published in Advanced Materials and Nature magazines shows a breakthrough in the usage of copper wire and how it can store energy. The research could mean even smaller electronics and clothes that act as batteries!
A nanotech scientist believes by using a thin sheath that surrounds lightweight electrical copper wire, he can store energy. We already know that all metals, including copper, form crystals that have free floating electrons that can move between associated atoms. That’s why electrical charges can come from one end of a wire to the other – basically electrons are shoving each other out of the way for the charge to move. Copper does this extremely well. But, now, the same wire that transmits electricity can also store extra energy.
