Claims20
An electrode for an electrochemical lithium battery cell, the electrode comprising:
- a bulk material that includes a plurality of voids dispersed substantially throughout the bulk material, wherein the bulk material comprises silicon.
A method of forming an electrode for an electrochemical lithium battery cell, the method comprising:
- providing hollow silicon spheres;
- providing silicon nanodots;
- mixing the silicon spheres and the silicon nanodots to form a composite mixture;
- molding the composite mixture to a predetermined shape;
- heating the molded composite mixture to melt the silicon nanodots without melting the silicon spheres;
- and
- cooling the molded composite mixture to cure the melted silicon.
