1. A method of producing multi-functional particulates of graphene-protected conducting polymer gel network-encapsulated anode particles for a lithium battery, said method comprising:
a) Dispersing a plurality of primary particles of an anode active material, having a diameter or thickness from 0.5 nm to 20 μm, and multiple graphene sheets into a precursor to a conducting polymer gel network to form a suspension; and
b) Forming said suspension into micro-droplets and, concurrently or sequentially, polymerizing and/or crosslinking said precursor to form said multi-functional particulates;
wherein said conducting polymer gel network comprises a polyaniline hydrogel, polypyrrole hydrogel, or polythiophene hydrogel in a dehydrated state.
