1. A Li-ion battery comprising:
an anode electrically connected to an anode current collector;
a cathode electrically connected to a cathode current collector;
a separator interposed between the anode and the cathode; and
an electrolyte ionically coupling the anode and the cathode,
wherein an anode composition of the anode comprises silicon (Si),
wherein an electrolyte composition of the electrolyte comprises LiPF6 salt,
wherein a cathode composition of the cathode comprises (i) active Li-comprising cathode material selected from lithium cobalt oxide, lithium nickel cobalt aluminum oxide (NCA), lithium nickel cobalt manganese oxide (NCM), or a lithium metal oxy-fluoride and (ii) a high capacity Li-comprising cathode additive, and
wherein the high capacity Li-comprising cathode additive exhibits at least about 10% higher volumetric capacity than the active Li-comprising cathode material,
wherein the high capacity Li-comprising cathode additive is in direct contact with an electrically conductive material, and
wherein the electrically conductive material is arranged as a shell layer or a coating of the high capacity Li-comprising cathode additive.
