1. A method of electrodepositing a protective carbon coating on to the surface of cathode or anode materials used in Li-ion batteries, using an organic solvent, the method comprising:
(a) immersing a working electrode and a counter electrode into an organic solvent comprising a carbon source in an ambient atmosphere;
(b) electrode positing a carbon coating onto a surface of the working electrode from the organic solvent at a temperature ranging from −5° C. to 50° C. removing the carbon coated working electrode from the organic solvent;
(d) rinsing the carbon coated working electrode with the organic solvent in which the carbon was electrode posited; and
(e) drying the carbon coated working electrode under vacuum.
