摘要： A device for converting a carbon pill into graphene is provided including a space between at least two electrically conductive surfaces, wherein the electrically conductive surfaces are configured to support a carbon pill in the space. The device also includes at least two electrodes electrically coupled to the at least two electrically conductive surfaces. The device also includes a power supply connected to the electrodes for passing a current through the electrodes to convert the carbon pill into graphene. A carbon pill for graphene conversion is also provided including a first carbon material for synthesizing to graphene by joule heating. The first carbon material is compressed from a powder form into a pill form. The carbon pill includes a second material for at least one of binding the first carbon material from a powder form into a pill form and improving conductivity of the first carbon material.
