Silicon promises longer-range, faster-charging and more-affordable EVs than those whose batteries feature today's graphite anodes. It not only soaks up more lithium ions, it also shuttles them across the battery's membrane faster. And as the most abundant metal in Earth's crust, it should be cheaper and less susceptible to supply-chain issues.
In fact, silicon's first documented use as a lithium battery anode even predates that of graphite— by seven years. But experiments with that element have been plagued by technical challenges—including volume expansion of the anode when loaded with lithium ions and the resulting material fracture that can happen when an anode expands and contracts.
