Graphene-based lithium battery material revolution -Lithium - Ion Battery Equipment
Since it was first artificially produced 12 years ago, it has become a global goal to bring graphene, which has broad application prospects in the fields of electronic information, new materials, new energy, and biomedicine, into the field of industrial production.(Lithium - Ion Battery Equipment)
Therefore, when Huawei's Central Research Institute Watt Laboratory announced at the 57th Japan Battery Conference that it "launched the industry's first high-temperature and long-life graphene-based lithium-ion battery", the country was boiling. Although later facts show that this "graphene-based battery" is not a "graphene battery", it does not affect people's expectations for Huawei's breakthrough in the field of graphene. (Actually I don't expect it at all)
In the summer of 2014, Ren Zhengfei, the founder of Huawei, said in his first interview with the media that a technological revolution would definitely break out in the next 10 to 20 years. The era of graphene subverts the era of silicon. According to this statement, it feels like a long way to go.
Is graphene lithium battery really a revolutionary technology?
Let's take a look at the advantages and disadvantages of graphene batteries.
advantage:
1: Low cost, 77% lower cost than lithium battery
2. The energy density is high, the battery life can reach 1000km, and the gasoline car can be completely abandoned
3: High stability and long battery life
Disadvantages: The above are all propaganda by the media and experts, whether it is true or false, who knows! Anyway, it has been almost 17 years, and I have never seen a graphene battery product.
Industry insiders believe that graphene may be too early. At present, graphene is still a product of scientific laboratories and can only be extracted from graphite in a very small amount. Therefore, the cost of graphene itself is very expensive, and it cannot be mass-produced, let alone commercialized in the market.
What's more, this is also competing with traditional lithium batteries, but how cheap traditional lithium batteries are, do you know, they are sold by tm.
At present, electric vehicles are charged for half a day and only run for dozens of miles, so they basically dare not go on the road. There is no practical value at all, there is no market at all, and there is no vitality at all. In order to popularize electric vehicles, graphene super batteries must be used to completely solve the fatal defects of long-term charging and short battery life of current electric vehicles. Only in this way can they be accepted by consumers and have unlimited vitality.
After charging for 5 minutes and running 1000 kilometers, I went, and high-voltage charging is not enough. Haha (just kidding) I can only count on the advent of graphene batteries.
