Currently, all devices on the market use batteries made with lithium-ion technology. Companies are working on improving the way of working of batteries in smartphones, and one of the breakthrough solutions for the entire market may be a graphene battery. This solution is being developed by Samsung for some time.
The fact that work on this project is ongoing has been known for some time, and some journalists even thought out that the Samsung Galaxy Note 10 could be the first phone equipped with a graphene battery, but as we know it hasn't happened. The real date when graphene batteries will be implemented into Samsung phones is 2021. This type of battery can allow to quickly charge your smartphone and to improve capacity of battery compared to lithium-ion units, and what is important - graphene is a very flexible material, which will give manufacturers great possibilities in terms of size adjustment of battery inside the device.
