- superhydrophobicity
-
"The key to long [battery] life is a property superhydrophobicity. This occurs when a drop of electorlyte or other liquid sits on top of a roughened nanostructured surface instead of wetting it. Zap the droplet with a burst of electricity or heat, however, and it wets the surface in a matter of milliseconds." Mechanical Engineering, Vol. 128/No. 11, November 2006. "Batteries that Keep", p. 22.
