Samsung Is The First To Apply For Patents On Graphene Battery Technology
Jan 17, 2019

The lack of mobile phone power can be said to be the biggest user pain point of smart phones at present. Although mobile phone developers have launched similar auxiliary solutions such as fast charge and charging treasure, even for new machines, most people still can't escape the fate of a day. . Why can't I have a battery that can store more power?

This idea may really come, and it may be a revolution in battery technology.

Samsung won a patent for graphene-based battery solutions in November last year. Now that this graphene battery has been basically manufactured, the model that will be used for the first time may be Samsung Galaxy Note10. If there is no accident, this will end the era of lithium-ion batteries that have been commercialized since 1991.

This technology is called "graphene spheres". Graphene is a material that is very suitable for use as a battery. It is also in excellent performance when it is in the laboratory stage. As a form of carbon, graphene transmits currents 140 times faster than silicon wafers, which is simply the battery of Pikachu.

Graphene batteries have three major characteristics: larger capacity, faster charging, and lower prices.

It is reported that Samsung's graphene solution can make the battery charge 45% higher than the lithium battery, that is to say, using the graphene battery, you can double the power without changing the size of the existing battery! Used on mobile phones, the original one-day battery can now be used for two days. As technology matures, battery capacity can be even greater.

The fast charging speed is the second bright spot of graphene battery, and the charging efficiency is more than 5 times faster than the traditional lithium battery.

According to reports, a graphene battery is fully charged in normal conditions only 12 minutes, and our current mobile phones generally use lithium-ion batteries, it takes about an hour to fully charge. And as the battery ages, we can clearly feel in our daily life that the charging time of the mobile phone battery will be longer and longer.

Although the battery fast charging technology has been upgraded many times, the fastest fast charging technology is also instantly eclipsed by the charging efficiency of graphene batteries, such as Huawei Mate20Pro's 40W fast charging, 30 minutes. It can only be filled with 70% of electricity.

The last advantage of graphene batteries is that they are expected to be cheaper than lithium batteries after mass production, and because of the material relationship, they will be more environmentally friendly.

Graphene batteries are used on laptops earlier than smartphones. In 2016, a company called Dongxu Optoelectronics claimed to have developed a graphene battery that fits the MacBook and named it G-King. The battery capacity shown at the conference was 4800mAh, which is similar to the traditional lithium battery capacity, but the charging speed soared, it only takes 13-15 minutes to fill a MacBook, 10-20 times faster than the lithium battery. Battery durability has also achieved a qualitative leap, with up to 3,500 cycles, seven times higher than lithium batteries.

The successful development of graphene is expected to become the power source of electric vehicles in the future. This involves another advantage of graphene batteries, which can maintain high stability in high temperature environments up to 60 degrees Celsius. Battery technology used to be the biggest barrier to the development of electric vehicles. Traditional batteries have been in a bottleneck stage after a long period of development, and each step of graphene battery technology breakthrough is tantamount to a dawn in the global battery industry.

Because of its unique characteristics, graphene is called "magic material", and scientists even predict that it will "completely change the 21st century." Professor Colin Bailey, vice president of the University of Manchester, said: "Graphite has the potential to revolutionize a wide range of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips."

At present, Samsung has applied for patents in Korea and the United States.

The concept of graphene battery technology, in fact, Huawei has long proposed and started research, and applied for patents for related technologies, before the introduction of the industry's first high temperature resistant long-life graphene-based lithium-ion battery. But unfortunately, Huawei did not continue to invest enough and explore this technology afterwards, which led to the development of this technology, which ultimately lags behind Samsung and is one step ahead of Samsung.

However, China's patent strength in graphene batteries is still not to be underestimated. At present, the cutting-edge technology of graphene batteries is mainly concentrated in China, the United States and South Korea, and in the 1238 patent applications related to graphene batteries worldwide, the technology originally originated in mainland China with a proportion of 45.79%, with 567 patent applications. .

We can also say that although Samsung has pioneered the development of graphene battery technology and is expected to be successful in mass production, according to the current situation, Samsung and Huawei (or other patent holders) may have another event in this matter. The patent war is going to be played.

In any case, the emergence of graphene batteries is a major innovation and upgrade of battery technology, breaking through the bottleneck of current battery life, the application in our life production has a very large imagination, will once again change our Life, at least start by changing our mobile phone.
