Silicon Nanotubes Could Boost Li-ion Battery Life

We’re always happy to hear about any advancements that can improve the performance of rechargeable batteries — particularly if those advancements could make lithium ion batteries robust enough for transportation and renewable energy storage applications.

A group of researchers at Stanford published a paper in March in the journal Nature Nanotechnology describing their work using silicon, as opposed to graphene, as an anode material in lithium ion batteries. While silicon has a larger charge storage capacity, it has inherent properties that make it less stable than graphene, which limits the lifecycle of silicon anodes to hundreds of cycles.
