Silicon is a promising anode material for rechargeable Li-ion battery (LIB) due to its high energy density and relatively low operating voltage. However, silicon based electrodes suffer from rapid capacity degradation during electrochemical cycling. The capacity decay is predominantly caused by
(i) cracking due to large volume variations during lithium insertion/extraction and
(ii) surface degradation due to excessive solid electrolyte interface (SEI) formation.
A robust binder polymer can help provide strong mechanical stability during the charge/discharge process to suppress the swelling of electrodes.
There are two models especially designed for Silicon-based anodes: BA-290S3 and BA-290S.
