Observing silicon anodes in action

Scientists in the United States working with silicon anodes for lithium-ion batteries have managed to model key mechanisms that lead to fast developing performance loss in the anodes. Understanding what causes the silicon to swell up and subsequently fall apart, the scientists say, is an important step to preventing it, and producing long lasting, high-capacity batteries.Among the many improvements being investigated for today's energy storage technologies, replacing graphite with silicon stands out, given that silicon has the potential to hold ten times more energy than graphite. Research into ...
