As one of the thinnest, hardest, and most conductive new nanomaterials found in the world, graphene is called “black gold†and “king of new materialsâ€. Scientists even predict that graphene will completely change the 21st century. "Black technology."
Since it was first produced artificially 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 industrialized production field.
Therefore, when Huawei's Central Research Institute Watt Lab announced at the 57th Japan Battery Conference that it "launched the industry's first high-temperature long-life graphene-based lithium-ion battery", the country was boiling. Despite the facts, this "graphene-based battery" is not a "graphene battery", but it does not affect the expectations of Huawei in the field of graphene. (The actual situation is that I don’t expect it at all)
In the summer of 2014, Huawei founder Ren Zhengfei said in a media interview for the first time that there will be a technological revolution in the next 10 to 20 years. The graphene era is a subversive silicon era. According to this statement, I feel that there is a long way to go.
Is the graphene lithium battery really a revolutionary technology?
Let's take a look at the advantages and disadvantages of graphene batteries.
Advantages :
1: low cost, 77% lower than lithium battery cost
2, high energy density, battery life can reach 1000km, you can completely abandon the gasoline car
3: high stability, long battery life
Disadvantages : All of the above are media and expert propaganda, whether it is true or not, who knows! Anyway, this has been almost 17 years, I have not seen graphene battery products.
The industry believes that graphene is probably too early. At present, graphene is still a scientific laboratory product and can only be extracted from graphite in a very small amount. Therefore, graphene itself is very expensive to manufacture and cannot be mass-produced, let alone commercialized in the market.
What's more, this is also competing with traditional lithium batteries, but how cheap is the traditional lithium battery, everyone knows, tm is to sell.
The current electric car is charging for a long time, only running for dozens of miles, 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, it is necessary to use graphene super batteries to completely solve the fatal flaws of electric vehicles with long-term charging and short battery life. Only in this way can they be accepted by consumers and have unlimited vitality.
Charging for 5 minutes, running 1000 kilometers, I went, high-voltage electricity charging is not good, haha ​​(just kidding) can only count on the appearance of graphene batteries.
