We have been waiting for several years for a revolutionary technology in the field of batteries, which would bring longer life and higher capacity. You charge a regular smartphone in about an hour to an hour and a half.
The battery capacity gradually decreases after approximately 300 cycles. Graphene batteries however, they could solve many of the problems of current batteries. Xiaomi tells us more about their use.
What are the problems of current batteries?
I'm sure you all know that well. Buy a new smartphone and charge it almost every day. During charging, it heats up and the battery capacity gradually decreases. In a year or two, you may feel a drop in capacity and you are charging it more and more often. Many manufacturers are adding fast chargers to their smartphones, which will at least shorten your charging time. At the same time, however, they reduce battery life.
The problem with conventional lithium batteries is production excessive heat and distinctive decrease in capacity after 300 to 500 cycles.
Graphene batteries and their advantages
Graphene conducts electricity well and can dissipate excess heat. For the first time, Xiaomi used a battery with graphene elements in a smartphone My 10 Ultrawhich is only available for the Chinese market.
He got double batterywhich excels in excellent endurance. The Mi 10 Ultra not only has an amazing camera, but also a great and advanced battery. Is graphene the future for batteries?
Zeng Xuezhong, President of the Mobile Phone Division, explained the huge benefits of using graphene technology in their flagship. Although it was a big challenge for the brand, they finally managed to debut with this technology on the Mi 10 Ultra. Compared to conventional lithium batteries, graphene holds its capacity above average, even when charged with a powerful charger, up to 120 W.
Xiaomi says they will keep the graphene batteries in their flagship 90% its capacity even after 2 years of use when charging with a 120 W charger. They estimate that the battery will have about a year 800 cycles.
The biggest revolution in batteries in recent years
Xiaomi had to invest a lot of time in research and development of these batteries, because getting quality and optimal graphene is not easy at all. In order for graphene to be used in a battery, it must meet high criteria. Subsequently, it must be thoroughly processed to ensure the continuous transfer of electrons with high conductivity.
This process is thus extremely complex and mass production is expensive. Nevertheless, Xiaomi is trying to see graphene batteries in the next flagship models. But we can expect it to be reflected in the price of smartphones. Graphene is still a very expensive material.
Since we can already find graphene batteries in the Mi 10 Ultra smartphone, we will definitely hear more about them. Many companies, such as Samsung or Tesla and Mercedes, are investing in their development.
