Tech-giant, Samsung, has designed a battery that can charge at a 5-times faster speed than the current lithium battery. This new prototype has been named as “Graphene ball” battery, and they say that the technology could enable a 45 percent increase in battery capacity (which could be revolutionary for smartphones and electric vehicles).
“Graphene is a single layer of carbon atoms from graphite, and is receiving much attention in the battery and display industry due to its physical, chemical stability. Graphene is 100 times more effective than copper in conducting electricity and displays remarkable electron mobility – 140 times faster than silicon – which makes it an ideal material for fast charge.”

The development came from Samsung’s research team at the Samsung Advanced Institute of Technology (SAIT) who have developed a battery using “Graphene” that can be completely charged in just 12 minutes.
Graphene Ball Batteries Highlights
- Graphene Ball batteries will complete charge in just 12 minutes
- The new technology will help manufacturers increase battery capacity in phones by 45 percent.
- The new batteries will support 5X charging speeds.
The institute collaborated with Samsung SDI and the Seoul National University’s School of Chemical and Biological Engineering to develop this material. The breakthrough provides promise for the next generation secondary battery market, which Samsung says will be particularly related to mobile devices and electric vehicles.
It has been more than a decade since Lithium-ion batteries were first commercialized and widely applied to markets for mobile devices. These batteries require charging times of at least an hour to fully charge, even with quick charging technology, and considered to have reached their limit for capacity expansion with use of new innovative materials.
Samsung claims that the new 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.
Dr Son In-hyuk, who led the project on behalf of SAIT, said, “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.”
