Si Anode

Si Anode

Si/C Composite
Silicon-based anode active material, Si Anode

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

Si active anode materials for 2^nd battery
5 ~ 20% to graphite-based anode materials
Complements the low output of graphite by adding silicon
Faster battery charging time and higher energy density compared to graphite
