Over the past two decades, carbon nanotubes have been considered one of the most promising nanomaterials. From the perspective of material properties, it combines high strength, high conductivity, high thermal conductivity, and extremely low density, and is widely regarded as a key component in future advanced material systems. However, for a considerable period of time, the development speed of the carbon nanotube industry has been significantly slower than market expectations. The high production cost, difficulty in large-scale manufacturing, and lack of stable demand on the application side have resulted in this material remaining between scientific research and small-scale industrial applications for a long time. Now, this situation is changing. With the continuous growth of demand for new energy vehicles, battery technology upgrades, and advanced composite materials, carbon nanotubes have gradually become a key material in multiple industry chains. From lithium battery conductive agents to lightweight composite materials, and then to flexible electronics and transparent conductive films, the application fields of carbon nanotubes are constantly expanding. According to predictions from multiple research institutions, the global carbon nanotube market is expected to maintain double-digit growth over the next decade, with the market size continuing to expand and the industry entering a true stage of scale. Quick overview of conductivity data of carbon nanotube powder Carbon nanotube type Conductivity/resistivity Multi walled carbon nanotubes (outer diameter 10-30 nm) Conductivity>100 S/cm Multi walled carbon nanotubes (outer diameter 5-15 nm) Conductivity 8-10 S/cm Single walled carbon nanotubes (low purity) Conductivity 100 S/cm Carbon nanotube conductive filler (composite with carbon black) Volume resistivity<0.01 Ω· cm (converted to conductivity>100 S/cm) 1. Industrialization turning point: rapid expansion of carbon nanotube production capacity Carbon nanotubes can be divided into two types based on their structure: single-walled carbon nanotubes and multi walled carbon nanotubes. Single walled carbon nanotubes are formed by curling a single layer of graphene, which has superior electrical properties, but is more difficult and costly to produce; Multi walled carbon nanotubes are composed of multi-layer coaxial tube structures. Although their performance is slightly lower, they are easier to achieve large-scale production, and therefore currently have a larger market application scale. In the early stages, the production of carbon nanotubes mainly relied on arc discharge method and laser evaporation method. Although these technologies could obtain high-quality materials, the production was limited and the cost was high. With the gradual maturity of chemical vapor deposition (CVD) technology, the production efficiency of carbon nanotubes has been greatly improved, laying the foundation for industrialization. In recent years, global ca...

Read MoreAgainst the backdrop of accelerated transformation of the global energy structure and synchronous growth in demand for advanced materials, how to achieve large-scale preparation of high value-added materials while reducing carbon emissions is becoming a core issue in the fields of materials science and energy engineering. Recently, a research team from the University of Cambridge published a study in the journal Nature Energy, providing a new technological path for this problem: by systematically reconstructing the methane pyrolysis and floating catalyst chemical vapor deposition (FCCVD) process, carbon nanotubes and clean hydrogen gas were produced synchronously without producing carbon dioxide by-products throughout the entire process. The key to this achievement lies in the deep transformation of the process logic of the existing methane pyrolysis system. Methane, as the main component of natural gas and biogas, has long been regarded as an important raw material for hydrogen production and carbon materials. However, the mainstream steam methane reforming process inevitably produces carbon monoxide and carbon dioxide, making it controversial in the "low-carbon hydrogen production" path. In contrast, methane pyrolysis reaction can theoretically directly decompose methane into solid carbon and hydrogen gas, avoiding oxygen participation in the reaction and eliminating the risk of carbon dioxide emissions from the root. In previous research and industrial practice, methane pyrolysis has been regarded more as one of the preparation routes for carbon nanotubes, and its byproduct hydrogen gas is usually ignored or only exists as an incidental product. The Cambridge University team has noticed that if the hydrogen yield can be significantly improved without sacrificing the quality of carbon nanotubes, methane pyrolysis is expected to be upgraded from a "material process" to a "material energy coupling process". This approach directly points to the long-standing efficiency bottleneck in the FCCVD system. The traditional FCCVD process uses methane as the carbon source and utilizes gas-phase catalysts to generate high-quality, high aspect ratio carbon nanotubes under high temperature conditions, which has significant advantages in fields such as battery conductive agents and high-end composite materials. But this process highly relies on external hydrogen input to dilute methane and prevent smoke and dust generation. This design imposes dual constraints on FCCVD during the amplification process: on the one hand, it requires a large amount of pre hydrogen production capacity, and on the other hand, the reaction gas usually adopts a one-way flow mode, with a large amount of unreacted methane discharged with the exhaust gas, resulting in low overall atomic utilization efficiency. The breakthrough of the Cambridge team is precisely based on this "one-way high loss" model. They proposed and validated a multi-stage circulating gas flow scheme, which allows me...
Read MoreUnder the wave of global electrification of automobiles, mainstream domestic and foreign car companies have increased their strategic layout of new energy vehicles, and new energy vehicles have entered a market driven high-speed growth period. The new energy vehicle market in our country maintains a rapid development trend. New energy vehicle batteries, electronic controls, and motors all use thermal interface materials such as thermal conductive materials and thermal conductive adhesives, which are expected to drive the demand for spherical alumina fillers. Electronic control: In order to reduce the thermal resistance of the heat source and water circuit, and improve the thermal conductivity efficiency of the module, it is usually necessary to apply thermal grease to the rigid interface between the IGBT module and the cold plate. With the filling of thermal conductive interface materials (such as thermal conductive silicone grease), the contact surface between the heat source and the heat sink will be fully in contact, which can significantly reduce the interface thermal resistance, significantly improve the heat dissipation effect, and reduce electrical losses. Motor: In the drive motor, the stator is used to generate rotational magnetism. High thermal conductivity adhesive is usually used to encapsulate the stator as a whole, which can reduce the thermal resistance between the winding and the stator core, improve the thermal conductivity of the insulation system, and reduce the temperature rise of the motor by about 10-18 ℃, thereby improving the reliability of safe operation of the motor. In the field of power batteries: As the "heart" of new energy vehicles, the thermal monitoring and management of power batteries are directly related to the overall performance of the vehicle, and have significant implications for the safe operation of the vehicle. Thermal conductive fillers used in power batteries, such as aluminum hydroxide, angular alumina, and spherical alumina, can all meet the needs of use. Considering the importance of safety control by power battery manufacturers and the differences in battery module structure and heat dissipation methods, the main thermal conductive filler currently used is spherical alumina, which serves as a thermal conductive and flame retardant material If you have any eqnuiry of aluminium oxide powder, we can offer nano particle and mirco particle, please feel free to contact us at admin@satnano.com
Read MoreAs one of the many thermal conductive materials, boron nitride is a unique one. Among the high thermal conductivity categories, it has high insulation, and among the high thermal conductivity and high insulation types, it is the cheapest. In the semiconductor industry's heat dissipation system, interface materials are the biggest bottleneck and the component with the lowest thermal conductivity. No matter what heat dissipation system you use, the bottleneck of interface thermal resistance will make the efforts of heat dissipation system engineers go to waste. The most promising alternative to alumina is boron nitride. The developed boron nitride thermal interface material has a longitudinal thermal conductivity of over 20 watts and a thermal resistance of 0.85k/cm2/w @ 1mm, surpassing all insulation thermal conductivity products, and achieving high flexibility and resilience. The production process is solvent-free. In laboratory simulation tests, compared with domestic 12 watt thermal pads, the heat source temperature drops by 23.5 ℃. In the application verification of optical modules, crush the carbon fiber thermal pad of foreign brands. Various indications suggest that replacing aluminum oxide with boron nitride is actually feasible. Of course, technological success does not necessarily guarantee market success. Currently, more and more material researchers are investing in the research of boron nitride, and there will always be someone who breaks through market barriers and brings new technologies and products to the market. The boron nitride industry will be a promising market, and domestic manufacturers should accelerate product research and development towards high purity, monocrystalline, large particle size, and low cost, in conjunction with the needs of thermal interface materials, to jointly promote industrial upgrading. SAT NANO is a best supplier of boron nitride powder in China, we can offer 100nm, 1-3um particle size, if you have any enquiry, please feel free to contact us at admin@satnano.com
Read MoreIn the explosive growth of new energy vehicles, energy storage power stations, consumer electronics and other fields, the "heart" of lithium batteries - the particle size of active materials - is becoming the core password that determines battery performance. From Tesla 4680 battery to CATL Kirin battery, from lithium iron phosphate to ternary positive electrode, the micrometer level adjustment of material particle size directly affects the charging and discharging speed, cycle life, and even safety boundary of the battery. Why are tech giants chasing the nanoscale? According to Fick's law, the diffusion time of lithium ions inside a particle is proportional to the square of the particle radius. Nanoscale particles (<100nm) shorten the diffusion path of lithium ions to 1/10 of that of micrometer sized particles, significantly reducing solid-phase diffusion resistance. For example, after reducing the size of lithium iron phosphate (LiFePO ₄) particles from 5 μ m to 100nm, the ion conductivity increases threefold, supporting high rate charging and discharging above 10C; ·The ternary cathode material (NCM) adopts nanoscale primary particle aggregates, which can maintain 85% capacity at a high temperature of 45 ℃. 2. The "dense network" of electronically conductive particles forms denser contact points in the electrode, theoretically improving the efficiency of electron conduction. Experimental data shows that the contact area of nanoscale lithium cobalt oxide (LiCoO ₂) particles increases by 40%, and the electrode resistance decreases by 25%; ·In the carbon nanotube composite negative electrode, the contact point density between nano silicon particles and conductive agent is increased by three times, and the efficiency exceeds 90% for the first time. 3. The "disruptor" of low-temperature performance exhibits faster lithium-ion deintercalation kinetics of nanoscale particles in a -20 ℃ low-temperature environment. According to actual testing of a certain brand of electric vehicles, batteries using nano positive electrodes can still release 85% of their capacity at -15 ℃, while traditional materials can only release 60%. 4. The small particle size of the "counterattacker" of cycle life can alleviate the concentration stress gradient during deep charging and discharging. According to data from Ningde Times Laboratory, the capacity retention rate of nano ternary materials reaches 82% after 3000 cycles, which is 15% higher than that of micron level materials. Small particle size 'fatal injury': how to solve the three major hidden dangers? 1. Agglomeration phenomenon: The high specific surface area (up to 100m ²/g) of nanoparticles from the "efficient channel" to the "island of death" leads to a significant increase in surface energy, making agglomeration highly likely to occur. For example, after the aggregation of nano lithium iron phosphate in the slurry, 20 μ m sized pores appear on the coated electrode, resulting in a threefold increase in local c...
