Samsung set to ditch lithium ion batteries for graphene, and here’s why

Samsung phones will have super fast graphene, rather than lithium, batteries within the next two years.

According to leaker Evan Blass, Samsung is developing graphene batteries for its smartphones — and we could see the first ones arrive as soon as next year. The reason for the change is clear: exceptionally fast charging. Reportedly a full charge will now take just half an hour on a graphene battery, and despite recent leaps forward in fast-charging that would still be a significant improvement on the standard lithium ion battery.

The news is the latest update we’ve heard since Samsung reported in 2017 that they had developed a graphene ball that could charge 5x faster than standard phone batteries (reported by Cnet). So why is it taking so long for the batteries to make it onto the market? Blass surmises that’s it’s simply a question of economics: “they still need to raise capacities while lowering costs.” Once that balance is found, this tech innovation could be a true game changer.

This news comes shortly after the release of Samsung’s latest flagship phablet, the Galaxy Note 10. It boasts an impressive 3500mAh battery, while it’s big brother — the Galaxy Note 10 Plus — has a whopping capacity of 4300mAh. But they’re not just about batteries. While both run on the powerful Exynos 9825 chip, specifications diverge significantly. The Galaxy note 10 has an 6.3-inch 1080 x 2280 resolution screen, with 8GB of RAM and a triple camera set-up; meanwhile, the Galaxy Note 10 Plus has an even larger 6.8-inch screen with a sharper 1440 x 3040 resolution, 12GB of RAM, and its triple rear camera is complemented with a Time of Flight 3D sensor.

With all the recent innovations in smartphone batteries, from huge capacities to Qi wireless charging, you might have thought there was nowhere else to innovate. But graphene technology could point towards an era of even faster charging. All that’s left to be seen is how pricey is it, and whether the capacity will be enough to satisfy demanding users.
