How well shall it conduct? Don't hope to compete with metals!
Graphite parts conduct electricity, rather well - they serve as battery electrodes for instance. Resists corrosion nicely. Most likely candidate for electrochemistry.
Graphite spray can also be bought easily. It serves on insulating materials before depositing films of copper or nickel electrochemically.
Plastics can be loaded with graphite powder. Used for casings of electronic boards. They won't carry amperes nor provide electromagnetic shielding, but are excellent against static electricity. Similar efficiency from graphite fibres in polymers.
