Self-healing Battery Prototype (image) DOE/SLAC National Accelerator Laboratory Caption 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.
