1. A composition comprising:
a conducting agent; and
an electrochemically active material,
wherein the conducting agent is a composite, and the composite comprises:
particles comprising SiO2 and a silicon oxide of the formula SiOx wherein 0<x<2; and
graphene,
wherein graphene is directly on a surface of the particles, and
wherein the graphene surrounds and interconnects the particles, which are embedded in the graphene,
wherein the composite and the electrochemically active material are different materials, and
wherein an amount of the composite is in a range of about 0.7 part by weight to less than about 1 part by weight, based on 100 parts by weight of the total weight of the composite and the electrochemically active material.
