International Classification:

H01M 4/36
H01M 4/38
H01M 4/60

Abstract:

Provided are active materials for electrochemical cells. The active materials include silicon containing structures and treatment layers covering at least some surface of these structures. The treatment layers may include aminosilane, a poly(amine), and a poly(imine). These layers are used to increase adhesion of the structures to polymer binders within active material layers of the electrode. As such, when the silicon containing structures change their size during cycling, the bonds between the binder and the silicon containing structure structures or, more specifically, the bonds between the binder and the treatment layer are retained and cycling characteristics of the electrochemical cells are preserved. Also provided are electrochemical cells and fabricated with such active materials, methods of fabricating these active materials and electrochemical cells and devices containing electrochemical cells fabricated with such active materials.
