Stanford researcher claims lithium ion breakthrough

Stanford University Materials Science Asst. Prof Yi Cui had developed what is claimed to provide a breakthrough in electrical energy storage. Instead of having an anode comprised of a solid mass of silicon and carbon, Cui and his research team have developed one based on a bundle of silicon nanowires. The limiting factor of traditional designs is that the as the silicon absorbs the lithium ions during charging, it swells and then contracts during discharge. Over time this causes the anode to crack, reducing the battery's capacity. The work ... Read more →
