Self-healing electrodes could make li-ion batteries last 10x longer

Researchers at Stanford University and Department of Energy's SLAC National Accelerator Laboratory have made a pretty big breakthrough in lithium-ion battery technology
The university reports, "Silicon electrodes swell to three times normal size and shrink back down again each time the battery charges and discharges, and the brittle material soon cracks and falls apart, degrading battery performance.
