2021/2/19"In graphite anodes, six atoms of carbon are needed to store one lithium ion, so the energy density of these batteries is low," explained Dr. Marta Haro, first author of the study. "Silicon anodes can store ten times as much charge in a given volume [as] graphite anodes—a whole order of magnitude higher in terms of energy density," said Dr. Haro.
