Over the past few years, smartphone manufacturers have managed to significantly speed up the process of charging the batteries built into the device. Samsung Galaxy Note10+ remains the current record holder, but the company is already preparing a model with a graphene battery.
According to the authoritative informant Evan Blass, Samsung is actively engaged in the development of graphene batteries. The release of a smartphone with such a battery may take place in the next year or two. According to the insider, it will take only half an hour to fully charge the new power source.
The main problem, which is now solved by the engineers of the South Korean company, is increasing the capacity and reducing the cost of such batteries. Graphene has been repeatedly called the best alternative to lithium-ion batteries: it can hold a large capacity and is not prone to rapid degradation over time. But in the 15 years since the discovery of the two-dimensional form of carbon, the reduction in the cost of its production is too passive.
Previous leaks indicated that Samsung finished working on graphene batteries in 2018, but the company itself did not give official comments on this matter.
