Mesoporous Graphene for Lithium-ion batteries [2020]
Graphene has a theoretical capacity of 744 mAh/g with outstanding electronic mobility at 10,000 cm2/V and extremely high lithium diffusivity at 10-7 – 10-6 cm2/s, it holds great promise as an anode material for high-energy-power lithium-ion batteries.
But the problem has always been producing high quality graphene sheets as we know that any defect will decrease the electric conductivity, electrochemical and structural stability which in turn has a negative effect in power density and Coulombic efficiency.
So far tests conducted with graphene yielded unfavorable results due to how difficult it was to produce high quality sheets, but in this research, titled High-quality mesoporous graphene particles as high-energy and fast-charging anodes for lithium-ion batteries, they were able to improve high quality sheets yield by chemical vapor deposition using a mesoporous Magnesium Oxide as a template and catalyst to start the process and adding an additional step with microwave radiation.
They basically grew nitrogen-doped graphene within the pores of the Magnesium Oxide template.
The idea is straight forward, you have a structure full of holes whereby using chemical vapor deposition, the nitrogen-doped graphene accumulates in these pores reacting with each other and turn forming a graphene sheet, all you need to do now is to submit the structure to an etching process to chemically remove the Magnesium Oxide template.
