[Haichuan New Energy] The new aluminum-graphene super battery developed by Zhejiang University can charge for 2 hours for 2 hours
Thread Content
Recently, a superb team from the Department of Polymer Science and Engineering of Zhejiang University developed a new aluminum-graphene battery. This kind of battery can work in an environment of minus 40 degrees Celsius to 120 degrees Celsius, and can be said to be resistant to both high temperature and severe cold. In an environment of minus 30 degrees Celsius, this new battery can achieve 1,000 charge and discharge performance without loss, and in an environment of 100 degrees Celsius, it can achieve 45,000 stable cycles. This new type of battery is flexible and retains its full capacity after being bent 10,000 times ； Moreover, even if the battery core is exposed to flame, it will not catch fire or explode. On December 15, the related paper Ultrafast all-climate aluminum-graphene battery with quarter-million cycle life was published in Science Advances. The first author is Dr. Chen Hao from the team.
Aluminum-graphene batteries light up LED light strings printed with "ZJU120" Compared with lithium batteries, the aluminum-graphene batteries developed by Gaochao's research group show obvious advantages: Generally, the specific capacity of batteries will continue to decrease with repeated charging and discharging. This is what the saying goes and is not durable. But this "unremarkable" aluminum-graphene battery performs well at this point. If one charge-discharge cycle is regarded as one cycle, this battery will experience 250,000 cycles and still have a specific capacity of 91%, with almost no loss. If a smartphone uses this kind of battery, it can last nearly 70 years even if it is charged 10 times a day.
My God, are mobile phone manufacturers happy or worried?
Reports say it will take some time, but we have just found this method so far
