Stanford materials scientist Yi Cui has found a way to create a silicone anode. Scientists knew that this material would create, at least theoretically, an enormous 10 fold increase in charge capacity but they were never able to achieve it. The problem was the silicone anode would crack or degrade due to extreme expansion. That was overcome by creating a an anode out of silicone nanowires. The space between the nanowires would allow for the expansion to take place without the anode cracking. (See picture above) As always, click heading for full article.
