Graphene batteries will be used in Samsung phones as early as 2021

The battle for consumers is in full swing. And Samsung decided to be the first phone manufacturer to test the technology with graphene batteries. In this case, smartphones will be charged in a little less than half an hour.

Invention patent

Back in 2017, in November, engineers from the Samsung Advanced Institute of Technology made a successful synthesis of so-called graphene balls, thanks to which it was possible to increase the efficiency of lithium-ion batteries by almost 50%.

After the successful introduction of the synthesized cells into the cathode and anode of a lithium-ion battery, the full charge rate from 0% to 100% increased fivefold. It took exactly 12 minutes.

For reference. A standard Li-Ion battery with a capacity of 3000 - 5000 mAh takes at least one and a half hours to be fully charged.

After successful laboratory tests, Samsung patented its development both in South Korea and in the United States of America.

Why are graphene batteries being introduced?

In our world, everything is accelerating and the requirements for charging phone batteries are constantly increasing. So the so-called fast charging technologies are gaining more and more popularity: Qualcomm Quick Charge, Huawei SuperCharge either Oppo VOOC.

But even using such technologies, the time to fully charge a 4000 mAh phone is just under one hour. And that's slow by modern standards.

Graphene batteries will give the industry not only much more energy-intensive batteries with the same dimensions, but they will also allow actively experimenting with the release of flexible smartphones, as they have sufficient elasticity.

According to preliminary information, phones with new batteries may be released to the general public at the end of 2020 or in the first half of 2021. An article with the calculations of engineers can be read in the scientific journal Nature.
