What you know about graphene: A metamaterial is stronger than steel, harder than diamond but thinner than a sheet of paper


Graphene batteries will overcome almost all the weaknesses of existing Li-ion batteries. Because graphene has good electrode conductivity, it can charge quickly and discharge better due to significantly reduced internal resistance. Graphene batteries promise to charge up to 5 times faster than li-ion batteries, 3 times longer battery life and 5 times longer charge cycles before batteries need to be replaced.



Big companies like Samsung and Huawei are currently actively researching and developing graphene-based batteries on their phone devices, and it is likely that the first prototypes will be released in 2022. Also This type of battery will also be widely used in the electric vehicle industry. However, it is clear that the battery industry is notoriously “conservative” and with little change, so the change is very unlikely and will force us to wait.

In addition to batteries, there are countless applications that graphene can bring, such as microprocessor or sensor. Imagine a thin chip the size of a paper, or even thinner, implanted in the blood to monitor real-time insulin levels, or the patient’s blood pressure. Thanks to their extremely thinness and high tensile strength, these graphene electronic components can also be woven into clothing fabrics or permanently stuck to the skin.

Graphene also contributes to the development of Photonics by integrating graphene into light-sensitive chips, cameras or light sensors. This improves light sensitivity, making it even possible to capture dim light waves across both the visible and the invisible spectrum. This will revolutionize the quality of cameras, telescopes, and even medical tools.
