Technology is ever-changing and so has the specifications on the inside. Besides being more powerful, the handsets have also got more long-lasting over time given the constant software optimisations and increasing battery capacity. But, Samsung is planning to raise the bar of smartphone batteries this time.
The South Korean tech firm has managed to make better handset batteries by using a ‘graphene ball’ in place of lithium. The firm’s research arm — Samsung Advanced Institute of Technology (SAIT) has made this possible in collaboration with Seoul National University’s School of Chemical and Biological Engineering.
The new battery material also gives five times faster charging speed than the typical lithium-ion batteries used in devices.
Samsung claims that a battery made with the graphene ball will be able to hold 45% capacity than a lithium one. While the current lithium-ion batteries take about an hour in getting fully charged, these new batteries will be able to recharge fully in just 12 minutes.
“In theory, a battery based on the “graphene ball” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60 degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles,” said Samsung.
The full findings of SAIT were published in Nature Communications in an article entitled, Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities this month.
“Our research enables mass synthesis of multifunctional composite material graphene at an affordable price. At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles is growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends,” said Dr. Son In-hyuk, who led the project on behalf of SAIT.
Although Samsung’s new discovery sounds enticing, users, unfortunately, won’t be seeing it in real life anytime soon. The company has filed a couple of patents on the tech and can only bring it in markets once it has been granted. In all likeliness, we might not see this coming in smartphones next year.
It may dedicate some extra time in testing these new batteries as they are not willing to repeat the Galaxy Note 7 history again.
