▎ 摘　　要

NOVELTY - The method involves reacting reduced graphene oxide (rGO) with the oxygen in the presence of ambient energy. The rGO is impregnated with alkali. The rGO is pure rGO and a source comprised with rGO. The coal is selected from the group consisted of sub-bituminous coal, bituminous coal, anthracite coal, non-coking coal, and coking coal. The coal is oxidized to produce rGO. The ambient energy is selected from the group consisted of electromagnetic energy, solar energy, radiant energy, and thermal energy. USE - Method for producing electrical energy from carbonaceous material using ambient energy. ADVANTAGE - The method provides a simple, cost-effective and energy efficient method/system to overcome the problems associated with currently used methods/systems. The method produces electrical energy from carbonaceous material using ambient energy. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a cell for producing electrical energy; and (2) a system for producing electrical energy. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the detection of potential of about 460 mV in presence of air.
