Scientists invent self-healing battery electrode
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. The secret is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation, according to the research.<img src="http://feeds.feedburner.com/~r/sciencedaily/~4/f6fsau3F_04" height="1" width="1"/>
