Samsung Releasing Smartphone Using Graphene Battery for 15-30 Minute Charging in 2020

Samsung will release a smartphone using new fast chargoing graphene battery technology that can fully charge in under 30 minutes according to gadgets leaker Evan Blass (@EVLeaks).

Samsung will release a smartphone powered by new graphene battery technology that can fully charge in under 30 minutes in 2020, or possibly 2021. This will be three to five times faster than today’s lithium-ion batteries which take about 90 minutes to charge.

In 2017, Samsung Advanced Institute of Technology (SAIT) announced they had developed a “graphene* ball,” a unique battery material that enables a 45% increase in capacity, and five times faster-charging speeds than standard lithium-ion batteries. The breakthrough provides promise for the next generation secondary battery market, particularly related to mobile devices and electric vehicles. In its research, SAIT collaborated closely with Samsung SDI as well as a team from Seoul National University’s School of Chemical and Biological Engineering.

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.

Nature Communications – Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities

Improving one property without sacrificing others is challenging for lithium-ion batteries due to the trade-off nature among key parameters. Here we report a chemical vapor deposition process to grow a graphene–silica assembly, called a graphene ball. Its hierarchical three-dimensional structure with the silicon oxide nanoparticle center allows even 1 wt% graphene ball to be uniformly coated onto a nickel-rich layered cathode via scalable Nobilta milling. The graphene-ball coating improves cycle life and fast charging capability by suppressing detrimental side reactions and providing efficient conductive pathways. The graphene ball itself also serves as an anode material with a high specific capacity of 716.2 mAh g−1. A full-cell incorporating graphene balls increases the volumetric energy density by 27.6% compared to a control cell without graphene balls, showing the possibility of achieving 800 Wh L−1 in a commercial cell setting, along with a high cyclability of 78.6% capacity retention after 500 cycles at 5C and 60 °C.

  1. I charge mine while I sleep, so I’m not that excited by 12 minute charging rates. The graphene battery still goes down to 80% within a year and a half assuming that you charge your phone nightly. That’s significant degradation. My 2 year old $300 Samsung lion watch battery, barely lasts a day now. My $300 EcoDrive watch, however, has lasted 20 years. Phone companies won’t be happy if people keep their phones for 5 years just like they do with their laptops. Planned obsolescence… Gold nanowire batteries promised little-to-no degradation at 200,000 cycles. Wake me up when a real breakthrough in cycle-life happens.

  2. So many battery breakthrough stories. This does seem to represent a step-change. We’ll have to see how it pans out. If it gets proven in phones, EVs will be next. Fast charging is very important for some applications like the taxi industry or long distance driving.

  3. Thanks for explaining the difference. This is the advantage of NBF, you can (usually) get a non-troll discussion of the issues.

  4. scrunched up platelets is easy compared to large area sheet graphene, they might even be using waste from platelet production for other graphene manufacturing!

  5. Graphene is not hard to produce, what is hard to produce are large sheets of high quality defectless graphene.

    But this graphene-ball is not a 2-D structure, but a 3-D structure, so I doesn’t look like it needs those hard to produce large sheets of graphene.
