Recently, there is a new type of battery is developing that has silicon anode which is able to absorb 8 times more Li-ions than graphite anode.

But if I no make mistake the main limitation of Li-ion battery is its cathode, not anode.
Usual graphite anode has specific capacity 372 mA·h/g while typical cathode 100-180mA·h/g. So there seem to be no sense to increase capacity of anode unless we have much more capacitive cathode.
