'Charging 5-minute call for two hours', I believe everyone on the ad will not be unfamiliar with fast charging technology to ensure that users use the phone when charging efficiency, but now on the market are the phone with lithium battery material, So the battery itself does not have much improvement in capacity.
But with the popularity and popularity of the former smart big screen machine, users have also been suffering from battery life problems.But recently there was news that the Zhejiang University team has developed a highly advanced - graphene battery.Through experimental data Display, this kind of battery only needs 1.1 seconds to be fully charged.
So fast charging speed, many users have doubts about the safety of this material battery, this battery is safe?
Such graphene batteries can withstand high temperature and cold, in the temperature range of minus 40 degrees Celsius to 120 degrees Celsius can work. And the new battery has a flexible effect, the bending of 10,000 times the capacity can be fully maintained. It is also worth mentioning that, even if the batteries of such batteries are exposed to fire, they will not cause a fire or explosion.
This graphene battery is also more durable than the traditional lithium batteries, the battery capacity can still be as high as 90% after 250,000 cycles, or 70 years if the user charges 10 times a day, but is limited by the yield Cost, this new type of super-battery has not yet entered the production stage, but still very much worth the wait.
