GRAPHENE BATTERY The main difference between solid-state batteries
and graphene-based batteries is in the composition
of one or both electrodes. The change primarily lies
in the cathode, but carbon allotropes can be utilized
in the anode as well.
The cathode in a traditional battery is purely
composed of solid-state materials, whereas in a
graphene battery the cathode is a composite-a
hybrid material consisting of a solid-state metallic
material and graphene. The amount of graphene in
the composite can vary, depending upon the
Lithium-ion stores up to 180Wh of energy per
kilogram while graphene can store up to
1,000Wh per kilogram.
Graphene can maximize the heat dissipation
performance of mobile phones and allow CPU
Maintain it at its best and significantly improve
the user experience.
In October 2018, the graphene liquid cooling
technology adopted by Huawei's Mate 20 X
mobile phone products officially marked the
beginning of the commercialization of graphene
Graphene has high optical permeability and can
be used to make foldable and stretchable
Compared with the traditional indium tin oxide
ITO conductor material, not only the mechanical
strength and flexibility are excellent, but also the
preparation process is environmentally friendly
and requires fewer resources.
Besides, with the continuous improvement of the
production process, the production cost of
graphene is expected to be much lower than the
traditional indium tin oxide touch screen.
Research has proven that graphene exhibits some toxic qualities.
Scientists discovered that graphene features jagged edges that can
easily pierce cell membranes, allowing it to enter into the cell and disrupt
These are just but a few of the 'wonder material's advantages and
disadvantages and since the material is still in the research stage
much more is yet to be revealed.
