Energy storage batteries are playing an increasing role in the new energy and other fields, thus placing much higher demands on the performance of advanced lithium ion and other rechargeable batteries. The high electrical conductivity of carbon nanotubes (CNT) with their unusual high aspect ratios can enable an effective construction of a perfect, electrically conductive network in lithium ion batteries. The CNT-containing composite electrode materials in the battery can possess an extremely good electrochemical performance, significantly improving the capacity performance, rate performance and cycle life of the resulting battery under various application modes. Carbon nanotubes can form a more effective electrically conductive network, which could provide lithium ion batteries with high energy density for consumer goods, EV batteries with extra-long cycle and other batteries with the high rate charge and discharge, the high capacity density and the usage at ultra-high or low temperatures etc.
Carbon nanotubes have a large specific surface area and excellent electrical conductivity due to their unique hollow structure and nanometer size. When carbon nanotubes are used in the electrode material of activated carbon in the capacitor, they will help improving the charge storage, increasing the capacity and reducing the internal resistance of the capacitor. Because of their very good electrical conductivity, CNTs will provide the larger power output under the high-power current demand.
Lead Acid Battery
The addition of carbon nanotubes to the negative electrode of the lead acid battery can result in an increased electrical conductivity of electrode, giving rise to an improved performance consistency and a better cycle life of the lead-acid battery. It also increases the depth of charge and discharge of lead acid battery as well as the energy density.
Antistatic / Conductive Plastics
Only replace the conductive carbon black 1/3~1/5 by carbon nanotubes as the filler, plastic canremain original requirements of antistatic plastics. At the same time, it does not affect the original plastic properties but too much filler does. In the appropriate amount of CNT and graphene, it would improve the strength of plastic. If you need to achieve the conductive grade plastic,the CNT doesn’t need too much comparing the conductive carbon black as the filler.

CNT uniformly disperse in the rubber compound. performance in rubbers is based on creating an additional 3D network,embedded into rubber matrix. During the process the curing speed can be accelerated, and the elastic and plastic properties and structure of the rubber can not be seriously affected. CNT is used to increase the strength of rubber while maintaining flexibility and, in some cases, improving additional important properties: hardness, cohesive strength, dynamic fatigue strength, abrasion resistance, hysteresis losses, and others.

Electrostatic Paintable Polymers
Efficiency in automotive manufacturing is an important element in controlling costs. Improved electrostatic painting yields can be achieved for some automotive components by adding small amount of carbon nanotubes to the polymer matrix.

Fuel System Components
Since the beginning of the automotive industry, car designers have often chosen metals to support fuel systems. In the new generation of automotive design, more and more designers are turning to conductive plastics as a lighter weight option to metal. However, traditional conductive fillers can cause problems in fuel systems since they need to be added at such high levels that they can weaken the mechanical properties of the polymers. The high electrical conductivity and high aspect ratio of carbon nanotubes mean that they can enable conductivity in the polymers at very low loading levels. The result is lightweight conductive fuel system components without sacrificing strength and reliability.

Semiconductor wafer processing, hard disk drive assembly and LCD display assembly typically require handling equipment, process carriers and shipping containers to be electrically dissipative and low particulating. Carbon nanotubes enable the compounding of conductive or dissipative plastics due to their high electrical conductivity. In addition, their high aspect ratio (L/D) keeps the loading level required for conductive or dissipative plastics is considerably lower than with traditional conductive fillers. Since the filler loading is kept low than 0.5%, the potential for particulation is minimized and manufacturing yields are maximized. Finally, since the filler loading is kept low, the filled polymer will not become brittle like traditional filled polymers do and the product life time is maximized.
Carbon Nanotube Benefits: 1. High yield；2. Consistent ESD protection；3. Longer carrier lifetime due to filled polymer durability；4. High cleanliness and ultra-low particulation； 5. Cost effective
The traditional electronics manufacturing process is poised for a paradigm shift away from expensive photolithography toward inkjet technology.
