"Tin whiskers" could triple the capacity of lithium-ion batteries

For over 60 years, electrical engineers have been trying to minimize the problem of tin whiskers. Growing on tin-plated electronics, the needle-like structures get up to ten millimeters long, and can cause short circuits. Instead of trying to eliminate them, however, Washington State University’s Prof. Grant Norton has been looking into ways of growing them – albeit in a controlled manner. His research has led to the creation of a tin battery anode, which he claims could triple the capacity of lithium-ion batteries.
