2021/12/21

With the rapid development of science and technology, life is being changed by green energy. The sparkling photovoltaic panels, the incomparably tall wind power generation, and the lithium batteries that fill all aspects of life are all full of infinite vitality, and the development of these new energy sources, regardless of whether The production of photovoltaic panels, the production of wind power impellers, or the production of lithium batteries is inseparable from a unique material, that is, carbon materials.

So, what is carbon material? It is not our common coal, let alone the charcoal we grill. It is a series of materials composed of carbon atoms with their own structures and properties. Among the types of composite materials, carbon fiber, graphene, etc., there is a material called diamond, which is actually a carbon material, but due to the unique properties and scarcity of diamond, everyone is more accustomed to calling him diamond.
Speaking of which, what is the relationship between carbon materials and new energy? In fact, carbon materials play a pivotal role in the production process of new energy materials. Here is a brief introduction!

First, the photovoltaic field

Today's mainstream crystalline silicon photovoltaic cells, the most important substrate is monocrystalline silicon wafers, photovoltaic cells are formed by a series of fabrications on the surface of monocrystalline silicon wafers to form P-N junctions with power generation functions, and the most important monocrystalline silicon wafers , it is not born with such performance, it is through melting polysilicon at high temperature, and then performing long-range ordered recrystallization to form the best single crystal silicon, and in the process of high temperature melting and crystal growth, it is necessary to To form a cavity that can withstand ultra-high temperature, the carbon material has come to the most critical position. It can form this ultra-high temperature cavity (thermal field insulation material), not only requires carbon-carbon composite materials (Jinbo, Chaoma), but also High-purity graphite materials (Fangda) are required to start the production of monocrystalline silicon. With the rapid growth of photovoltaics this year, carbon materials in the photovoltaic field have been in a state of short supply, and this will continue to be maintained in the future. A state of scarcity!

Second, the wind power sector

With the development of wind power generation towards the sea surface and large-scale, traditional FRP blades can no longer meet the needs of large-scale and lightweight. At this time, carbon materials have come to the front of wind power again. It has become the best choice for wind blades. In the current situation that the diameter of the wind rotor has exceeded 120m, carbon materials can effectively reduce the overall weight by about 40% and the cost by about 15%. With further technological improvement, it is believed that the demand for carbon materials will be further improved!

Finally, the lithium battery

As lithium batteries have higher and higher requirements for battery capacity, cycle time, and cost, carbon anode materials have entered the historical stage of lithium batteries, especially with their excellent electrical conductivity, better crystallinity, and good layered structure. , is an ideal anode material, and with the continuous growth of electric vehicles on the road, the continuous increase in the amount of lithium batteries, carbon materials are playing an increasingly important role, in the near future, even if there are new breakthroughs in silicon carbon anodes , carbon materials will continue to play a key role in lithium batteries!

In summary, we can see that carbon materials are playing an increasingly important role in new energy fields such as photovoltaics, wind power, and lithium batteries by virtue of their excellent properties such as high temperature resistance, high strength, and electrical conductivity. , the future is full of stars and seas, and carbon materials, as their basic materials, simply have no upper limit. Therefore, we need to focus on the development of carbon materials. Here, we should give you an introduction, and you can continue to research on your own. After all, carbon materials There are many kinds, any one has a wide application market!

Speaking of this, I believe that I have a relatively simple understanding of carbon materials and new energy, and the focus is coming. For us, which carbon material companies are worthy of our attention, please continue to read:
