The ideal use of graphene as a battery is as a “supercapacitor.” Supercapacitors store current just like a traditional battery but can charge and discharge incredibly quickly. The unsolved trick with graphene is how to economically mass manufacture the super-thin sheets for use in batteries and other technologies.
Therefore, graphene is considered an attractive material for rechargeable lithium-ion batteries (LIBs), lithium-sulfur batteries (LSBs), and lithium-oxygen batteries (LOBs). In this comprehensive review, we emphasise the recent progress in the controllable synthesis, functionalisation, and role of graphene in rechargeable lithium batteries.
More recently, Chinese carmaker GAC has teased a graphene-based battery that can be recharged to 80% within just 8 minutes. We are gradually creeping closer to commercial viability, but remain a way off from mainstream adoption of graphene batteries.
Graphene batteries are often touted as one of the best lithium-ion battery alternatives on the horizon. Just like lithium-ion (Li-ion) batteries, graphene cells use two conductive plates coated in a porous material and immersed in an electrolyte solution.
Graphene slurry also exhibits excellent battery performance as a conductive agent for LIBs. At 100 mAg −1 current density, the first charge and discharge capacity are 1273.8 and 1723.7 mAhg −1, respectively, and the coulombic efficiency is 73.9%. The capacity retention rate of the anode is 84% (1070.2 mAhg −1) after 100 cycles at 200 mAg −1.
Emerging consumer electronics and electric vehicle technologies require advanced battery systems to enhance their portability and driving range, respectively. Therefore, graphene seems to be a great candidate material for application in high-energy-density/high-power-density batteries.
