Characteristics of silicon-based anodes

Si anode

They are mixed into silicon-based anode active materials and graphite-based anodes at about 5–20%.

More View

High capacity

About 10 times higher than the theoretical amounts
of Si (4,200 mAh/g) and graphite (372 mAh/g)
High efficiency

Increased efficiency achieved by mixing Si and graphite
Long life

Long life achieved through even carbon coating
Fast charge

Faster charge speed and higher energy density
of silicon in comparison to graphite
