Polymer-Coated Battery Electrode Heals Itself

Posted on the 19 November 2013 by Dailyfusion @dailyfusion
This prototype lithium ion battery, made in a Stanford lab, contains a silicon electrode protected with a coating of self-healing polymer. The cables and clips in the background are part of an apparatus for testing the performance of batteries during multiple charge-discharge cycles.

A team of researchers from Stanford University, along with scientists from the Department of Energy’s (DOE) SLAC National Accelerator Laboratory, has created the first self-healing battery electrode. A stretchy polymer that coats the self-healing electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation. Read more »
