Abstract: The present invention provides a process for making high energy density lithium rechargeable battery cathodes based on self-assembled monolayer. The cathode materials of the invention are prepared by immersing conducting substrates such as gold, silver, copper, and the like, in a milimolar solution of an organic disulfide. Thereby a self-assembled monolayer of an organic disulfides on a conducting substrate can be obtained capable of delivering high energy and power density after coupling with a material Lithium electrode anode in an electrolyte solution using Lithium salts and specific solvents and co-solvents.
