Increasingly efficient smartphones require better power, which would allow them to work at least for a full day without charging. Samsung engineers have developed a new lithium battery technology, using graphene, which doubles their capacity.
The modern smartphone is a practically pocketable PC that is very similar to what is offered by a home PC. Unlike the computer on our desk, it is not powered by electricity, but a battery that must be large enough to last for hours. Unfortunately, this is not the case and the batteries installed in modern smartphones are not capable of meeting high energy demands, so they need to be recharged during the day.
Perhaps we will soon be doing it a little bit less, because Samsung Electronics engineers have developed a new technology to produce battery cathodes using graphene, which should double the capacity of such a battery. The company has created a new coating that significantly increases cathode performance and slightly reduces the capacity of the cathode.
The use of graphene has increased their capacity by up to 1.8 times compared to standard lithium-ion batteries. It is also important that the process has no effect on the battery life, that is, a more capacious battery can be charged, which can be charged as many times as the batteries currently being sold.
