Abstract
In an embodiment, a Li-ion battery cell comprises an anode electrode with an electrode coating that (1) comprises Si-comprising active material particles, (2) exhibits an areal capacity loading in the range of about 3 mAh/cmto about 12 mAh/cm, (3) exhibits a volumetric capacity in the range from about 600 mAh/cc to about 1800 mAh/cc in a charged state of the cell, (4) comprises conductive additive material particles, and (5) comprises a polymer binder that is configured to bind the Si-comprising active material particles and the conductive additive material particles together to stabilize the anode electrode against volume expansion during the one or more charge-discharge cycles of the battery cell while maintaining the electrical connection between the metal current collector and the Si-comprising active material particles.
