Claim:
1. An electrode comprising: (a) carbon nanoparticles; (b) at least one of metal particles, metal oxide particles, metalloid particles and metalloid oxide particles; (c) 0.01 wt. % to 10 wt. % of a surfactant, wherein said surfactant attaches said carbon nanoparticles to said at least one of metal particles, metal oxide particles, metalloid particles and metalloid oxide particles by electrostatic attraction at a pH of between about 4 and about 11 to form an electrode composition, wherein said surfactant comprises one of a sulfate group, a sulfonate group, a phosphonium group, pyridinium group and an ammonium group; (d) 0.1 wt. % to 40 wt. % of a binder for forming said electrode composition into a film or membrane; wherein said electrode is an anode, and wherein said electrode has a specific capacity of at least 700 mAh/g of active material when cycled at a charge/discharge rate of about 0.1C.
