Because graphene has an unimaginable conductive ability, the concept of graphene battery has become a lifesaver to break through the bottleneck of current battery technology
.
In particular, any technological breakthrough in the domestic electric vehicle industry is linked
to graphene batteries.
Due to Tesla's success, almost the world has seen the future trajectory of the automotive industry, which is also the root of the hype of
graphene batteries.
In layman's terms, the core of battery technology is charging speed and power
capacity.
The reason why graphene batteries are hotly hyped is because the conductivity of graphene is several times stronger than that of copper or silver, which is only conductivity
.
However, the structure and structural properties of graphene and carbon atoms result in its capacity being only a quarter
of that of silicon in conventional batteries.
Then, in order to achieve theoretical efficiency, graphene batteries must combine
the advantages of the two.
Unfortunately, the existing technology and process cannot achieve uniform distribution of traditional silicon and graphene on nanometers, and even if this is achieved in the future, the cost constraint leads to mass production is a very distant thing
.
Another most fatal point is that in the test, the cycle life of the lithium battery with graphene as the negative electrode is very poor, and the charge and discharge are fast, but it fails twice and is obviously unusable
.
The national level is actively promoting the graphene industry, and graphene has been written into the "13th Five-Year Plan" of new materials
.
Zhou Changyi, director of the Department of Raw Materials of the Ministry of Industry and Information Technology, revealed at the 2015 Graphene Innovation Conference that the "13th Five-Year Plan", including the development of the new material industry, is being prepared and will be introduced
soon.
Among them, the graphene industry is expected to become a leading industry in the development of the new material industry, and the industrial scale will exceed 10 billion
by 2020.
The basic requirements of electric vehicle batteries are threefold: fast charging, large power capacity, and strong
durability.
At present, graphene only meets the point of fast charging, and graphene batteries for the electric vehicle industry are almost impossible
in the foreseeable future.
