Abstract. Graphene is a relatively new and promising material, displaying a unique array of physical and chemical properties. Although considered to be especially promising for the use in energy storage applications, graphene has only recently been implemented as an electron conducting additive for lithium ion battery cathode materials.
Lithium-Ion batteries and graphene batteries can be used to power similar devices and transfer energy in similar ways. Although both lithium-ion and graphene batteries share similarities in design and application, they differ greatly when it comes to speed of energy transfer, safety aspects, and service life.
Lithium-ion stores up to 180Wh of energy per kilogram while graphene can store up to 1,000Wh per kilogram. Graphene offers five times better energy density than a standard Li-ion battery. Finally
