Samsung is preparing a smartphone with a graphene battery

Modern smartphones, and any other mobile, wearable electronic devices, are becoming increasingly

more perfect, their functionality is growing, their powerincreases. Overall productivity almost doubles per year. But this does not happen with batteries, unfortunately, and powerful hardware and large smartphone screens eat up energy very quickly. Today, the main material for making batteries is lithium, and lithium-ion batteries are used in smartphones. These batteries have their advantages and disadvantages; the latter list includes strong heating during charging and use, as well as long charging times and small capacity. Smartphones have to be charged frequently, and it takes quite a long time for them to finish charging. But the Korean company Samsung intends to change the situation in the near future by creating graphene batteries instead of lithium ones for its smartphones.

What is known

According to Evan Blass, one ofthe most credible source of leaks, the Korean technology giant has long been developing brand new graphene-based batteries for its future smartphones. The first copies of smartphones with new batteries will appear on the market in 2020. Of course, this is not a whim of the company, it is a necessity, and the main advantage of the graphene battery is a very fast charge. For example, experts give an example with a 5000 mAh battery, it will charge for three hours on the basis of lithium, but on the basis of graphene this amount will be replenished from zero to one hundred percent in just thirty minutes. No matter how they tighten the quality of lithium-ion batteries, for several years now they have been practically at the same level, and graphene, although not a revolution, is already a significant breakthrough.

The company said they created a smalla battery in the form of a graphene ball, which showed a charging speed five times that of a conventional battery with the same current parameters. If they are much better, why is still not in the market. After all, graphene has been known for a long time?

Economic expediency

Experts suggest that the appearance of graphenebatteries for smartphones, this is only a matter of economic feasibility, benefits. The fact is that manufacturers still have a lot to move towards reducing the cost of such batteries. So far, apparently, it is unprofitable, but when the balance is reached, we will witness a not-bad innovative breakthrough.

Meanwhile, smartphone appetites are growing rapidly,The latest flagship Galaxy Note received a 4300 mAh battery. However, a 6.8 ”high-resolution display, an Exynos 9825 super-performance processor, a powerful modem for the latest generation of cellular networks, 12 gigabytes of RAM, as well as a triple rear camera consume energy faster than a regular user manages to replenish. Until a fundamentally new concept of batteries appears, until new materials appear, graphene technologies will provide a further increase in the characteristics of batteries for smartphones.
