AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-5 and 9-21 is confirmed.
Claims 22 and 23 are determined to be patentable as amended.
Claims 6-8 were not reexamined.
22. A battery cell, comprising:
an anode electrode;
a cathode electrode; and
an electrolyte ionically coupling the anode electrode and the cathode electrode,
wherein the anode electrode or the cathode electrode includes a battery electrode composite particle, the composite particle comprising:
an electrically-interconnected matrix having a three-dimensional, randomly-ordered structure forming internal pores within the matrix; and
a plurality of nanoparticles of a non-carbon Group 4A element or mixture thereof disposed within the internal pores of the matrix,
wherein the internal pores define an electrolyte-free pore volume within the composite particle that is different from a volume occupied by the plurality of nanoparticles of the non-carbon Group 4A element or mixture thereof [ ,
wherein the composite particle further comprises:
a coating disposed on at least a portion of an outer surface of the composite particle,
wherein the coating is configured to inhibit access of the electrolyte into the electrolyte-free pore volume defined by the internal pores] .
23. The [ A ] battery cell of claim 22, wherein the composite particle further comprises:
a coating disposed on at least a portion of an outer surface of the composite particle,
wherein the coating is configured to inhibit access of the electrolyte into the electrolyte-free pore volume defined by the internal pores [ , comprising:
the composite particle of claim 1.]
