Inspired by the structure of wood, engineers at the University of Maryland have used modified wood as a unique architecture for the negative electrode of a lithium (Li) metal battery, seeking to prevent some of the key factors that lead to battery failure. Li-ion shuttling in rechargeable batteries provides energy to power your phone, laptop, or even just a light bulb. When the battery is charged, the negative electrode: Li metal expands; and when it is discharged, the Li metal deflates...
