Samsung could launch phone with fast charge graphene battery as soon as 2020

Samsung Galaxy Note 9 fast charging

Smartphones are constantly improving and getting better and better specs, but one phone part that doesn’t seem to be getting better nearly as rapidly is the battery. A new battery from Samsung could help change that.

Samsung is working to have a new smartphone with a graphene battery in either 2020 or 2021. That’s according to prolific leaker Evan Blass, who adds that this graphene battery will be able to fully charge in under 30 minutes. However, Samsung is still working to raise capacities of these batteries while lowering costs.

Smartphones nowadays are powered by lithium-ion batteries which require at least an hour to fully charge and have likely reached their maximum capacity expansion. Samsung has been working on a graphene battery alternative, and back in 2017 it announced that it had developed a “graphene ball” battery material that offers a 45 percent increase in capacity and five times faster charging speeds than lithium-ion batteries.

Graphene is made of a single layer of carbon atoms from graphite and it’s 100 times more effective than copper in conducting electricity. It also offers electron mobility that’s 140 times faster than silicon, making it a great material for fast charging. Samsung touts that in theory, a battery using its graphene ball material could fully charge in only 12 minutes.

These graphene batteries sound like they could be a major improvement over the lithium-ion batteries currently found in smartphones. We’ll have to wait for the final product to see what the capacities are like, but the super fast charging that graphene batteries could offer means that you could plug in for 5 or 10 minutes and get a large portion of your battery charge back. And because it’s widely considered that lithium-ion batteries have reached their limit for capacity expansion, it could be good to switch to a new material and see what kind of capacities it could offer.
