Smartphones are getting faster and more capable with each passing year. But one aspect that has barely seen any changes is the battery technology. Most devices still rely on the tried and tested lithium-ion cells, however, graphene batteries could be the game-changer we’ve all been waiting for. So here are 3 ways it can revolutionize smartphones in the near future.

Faster Charging Speeds

One of the biggest advantages of graphene batteries is their ability to charge significantly faster than traditional lithium-ion batteries. Unlike most smartphones with lithium-ion batteries that take an around to fully charge even with fast charging, graphene batteries can be fully charged in mere minutes.

There have been demonstrations where graphene batteries being powered up with great speeds. Furthermore, unlike current fast charging technology, which can lead to battery life degradation over time, graphene’s high thermal conductivity helps reduce heat build up. In other words, graphene makes charging not only more efficient but safer as well.

Increased Energy Density for Longer Battery Life

The latest flagship smartphones with lithium-ion batteries that use silicon-carbon composite materials for higher battery capacities thanks to improved density. But graphene batteries boast much higher energy density right off the bat. Meaning, smartphones with this technology can store a lot more power for the same physical size as the current lithium-ion cells.

This also has many advantages with smartphones easily lasting more than a day with a single charge. Since graphene batteries can pack higher energy capacity, smartphones could also become slimmer and lighter without sacrificing battery life.

Longer Battery Lifespan

Battery degradation is a major issue with lithium-ion batteries as they lose capacity over time, requiring more frequent replacements. On the other hand, Graphene batteries, offer a much longer lifespan. A typical lithium ion battery can offer up to 500 to 800 charging cycles. However, graphene batteries can last well over 1,500 charge cycles before seeing any significant degradation.

This means that users who use their phones for multiple years need not worry about replacing batteries or battery life issues. Longer lasting batteries also go a long way in producing less electronic waste, which means that it is more sustainable and eco friendly as well.

Conclusion: The Future of Smartphone Batteries

To sum things up, Graphene batteries have the potential to revolutionize the smartphone industry with ultra fast charging that could take mere minutes, extended battery lifespan for reduced waste, and higher energy efficiency that could make battery life longer and smartphones thinner. Unfortunately, the technology is still too expensive to use as a commercial product, but the technology is still in development.

The post 3 Ways Graphene Batteries Can Revolutionize Smartphones appeared first on Gizmochina.

Samsung is playing with new battery technology from the past few months, even last year, they have registered a patent for the same. The Korean giant is working on graphene batteries which is said to be much better than the Li-ion batteries. Last year, the Advanced Institute of Technology has tested graphene batteries and found that these batteries can be charged in 12 minutes. It can last longer and deteriorate less which make it more stable to use in the smartphones. These properties of graphene batteries seem to be impacting the decision of Samsung to use it soon in their upcoming devices early next year.

Samsung graphene batteries can hold 45% more charge than the current lithium-ion batteries. Graphene battery cells can be charged five times faster than the present technology. It means same capacity lithium-ion battery will take 1 hour to charge whereas the graphene battery will take only 12 minutes. Unlike the Li-ion batteries, they deteriorate less with the usage and the passage of time. These are smaller in size, which will help manufacturers utilise the same space for adding up some other things in the smart devices. Most importantly, graphene batteries won’t randomly explode making it the best option for the phones.

As per the industry insider, Samsung is done with the development of graphene batteries and they are ready to use it into devices by next year. Currently, the production cost is high, but with time, the cost will gradually come down enabling all OEMs to replace the Li-ion batteries. These batteries do not impact the environment as much as like the current solutions.

As of now, no particular date is given by our insiders, but Samsung will begin using it soon. Samsung might become the first company to launch graphene battery along with the announcement of Galaxy S10 early next year. Even if it happens by next year, then Samsung will significantly win over all the devices in the battery department by a big margin.

Samsung Advanced Institute of Training (SAIT), a research wing of the South Korean company, has managed to synthesize a “graphene ball” through which lithium-ion batteries can be made to last longer and charge faster. In other words, it can increase the capacity of lithium-ion batteries by 45 percent as well as charge them five times faster.

The existing lithium-ion batteries can take around an hour to charge completely. The new technology can possibly reduce the charging time to just 12 minutes. It can be also used in electric cars in future as graphene ball batteries are able to maintain a temperature of 60 degrees Celsius.

The entire information on the findings of SAIT is available on Nature. SAIT created a three-dimensional graphene ball by synthesizing graphene with silica. The graphene balls were then used as anode and cathode for lithium-ion batteries. South Korea and the U.S. are the two regions were Samsung has filed a patent for this new technology.

The commercial use of lithium-ion batteries began in 1991 and since then it has been widely used in electronic devices. Because of its limitations, companies are now looking for alternatives. SAIT’s graphene ball technology appears very promising, but there is no guarantee whether Samsung will introduce it in its upcoming flagship smartphones like Galaxy S9 or Note 9.

SAIT is known for carrying out numerous technological innovations such as the development of the cadmium-free Quantum Dot materials that are used in Samsung’s flagship OLED TVs. In August, it had also opened an Artificial Intelligence (AI) lab in University of Montreal in Canada.
