“…Also, the limited energy density of AC‐based EDLCs cannot satisfy the increasing demand in the energy‐storage devices. Sumio Iijima's group75 outlined a general and rational strategy to fabricate an aligned high‐densely packed single‐walled carbon‐nanotube (SWNT) solid material by using the zipping effect of liquids to draw nanotubes together. The capacitance of this SWNT solid EDLC was around 80 F g −1 .…”

Increasing environmental problems and energy challenges have so far attracted urgent demand for developing green and efficient energy‐storage systems. Among various energy‐storage technologies, sodium‐ion batteries (SIBs), electrochemical capacitors (ECs) and especially the already commercialized lithium‐ion batteries (LIBs) are playing very important roles in the portable electronic devices or the next‐generation electric vehicles. Therefore, the research for finding new electrode materials with reduced cost, improved safety, and high‐energy density in these energy storage systems has been an important way to satisfy the ever‐growing demands. Symmetric electrodes have recently become a research focus because they employ the same active materials as both the cathode and anode in the same energy‐storage system, leading to the reduced manufacturing cost and simplified fabrication process. Most importantly, this feature also endows the symmetric energy‐storage system with improved safety, longer lifetime, and ability of charging in both directions. In this Progress Report, we provide the comprehensive summary and comment on different symmetric electrodes and focus on the research about the applications of symmetric electrodes in different energy‐storage systems, such as the above mentioned SIBs, ECs and LIBs. Further considerations on the possibility of mass production have also been presented.

“…Owning to these advanced properties as well as abundance of carbon on the earth, CNT is an important candidate to build flexible electronics. [25][26][27] However, it is seldom regarded as a TE material due to its poor Seebeck coefficient (< 60 μV/K) 28 and high thermal conductivity of a single tube (~ 250-10000 Wm -1 K -1 for single tube or aligned arrays) [29][30][31] . It has been reported that low thermal conductivities can be obtained in CNTs/conductive polymer composites and processed tubes.…”

n-Type thermoelectric (TE) materials was made from carbon nanotube (CNT) buckypapers. We used silver telluride (Ag 2 Te) to achieve electron injection to the CNTs. The TE characterizations on more than 50 samples show that the CNTs/Ag 2 Te hybrids exhibit negative Seebeck coefficients (e.g., n-type) from −30 to −228 μV/K. Meanwhile, the tunneling coupling between the CNTs and Ag 2 Te increase the electrical conductance to the range of 10 000−20 000 S/m, which is higher than each single component (CNTs or Ag 2 Te). These n-type TE buckypapers are flexible and robust with ZT values of 1−2 orders of magnitude higher than previously reproted for CNT-based TE materials. In addition, the preparation of such buckypapers are very simple compared to a tranditonal inorganic process, without the need for hot pressing or spark sintering. These n-type TE buckypapers can provide important components for fabricating CNT-based flexible TE devices with good conversion efficiency.
