Silicon's Second Chance: The Promise of the US Lithium Ion Battery with Silicon Anode

For over a decade, silicon has been the "holy grail" of anode materials. Its theoretical capacity (3,579 mAh/g) dwarfs graphite (372 mAh/g), promising a quantum leap in energy density. Yet, silicon's fatal flaw—massive volume expansion (up to 300%) during charging—has limited its commercial use to small percentages blended with graphite. Now, a combination of nanostructuring,...
