The requirement for high-performance lithium-ion batteries (LIBs) in electric vehicles and large-scale energy storage systems has become increasingly stringent and pressing in recent years [1, 2].For the anode, the conventional commercial graphite (372 mAh/g) is far from meeting the demand for high energy density.
Silicon-carbon batteries use a nanostructured silicon-carbon composite anode while lithium-ion batteries typically use a graphite carbon anode. The silicon-carbon anode can store over 10x more lithium ions enabling higher energy density. However, silicon expands dramatically during charging which led to mechanical failures early on.
