“…In most gravimetric data reported in the literature, the mass loading of active materials is less than 1 mg cmM a n u s c r i p t 9 14 mg cm -2 for Cu) are also included in the masses used to calculate the gravimetric data, the results become much worse than their reported values. In order to see the significance of using CNF films as light current collectors, we found capacity data for anode materials in a half cell configuration (SiNWs [11], metal oxide [15], tin [16], tin-copper alloy [17], mesocarbon composite [18], commercial graphite) with active material mass loadings larger than 5 mg cm -2 in the literature. The data are summarized in Table 1.…”

Although current collectors take up more weight than active materials in most lithium ion battery cells, so far research has been focused mainly on improving gravimetric capacities of active materials. To address this issue of improving gravimetric capacities based on overall cell components, we develop freestanding nanocomposites made of carbon nanofibers (CNFs) and silicon nanowires (SiNWs) as metal current collector-free anode platforms. Intrinsically large capacities of SiNWs as active materials in conjunction with the light nature of freestanding CNF films allow the nanocomposites to achieve 3 ~5 times improved gravimetric capacities compared to what have been reported in the literature. Moreover, three dimensional porous structures in the CNF films facilitate increased mass loadings of SiNWs when compared to flat substrates and result in good cycle lives over 40 cycles. This type of nanocomposite cell suggests that 3D porous platforms consisting of light nanomaterials can provide for higher gravimetric and areal capacities when compared to conventional battery cells based on flat, heavy metal substrates.

“…Mesocarbon microbeads (MCMB) was used as the anode material in this study as it regularly shows good performance thanks to its high packing density and narrow particle size distribution, ranging from 1t o4 4 m. MCMB exhibits good capacity retention and rate capabilities due to edge-plane surfaces [31][32][33][34]. We first studied two cellulose-based salts: (i) NaCMC obtained from two different suppliers showing different viscosities and performance, and (ii) lithium carboxymethyl cellulose (LiCMC) synthesized and characterized in-house.…”

“…Although the previous methods achieved high electrochemical performance, the processes seem relatively complicated. Using vacuum or pressure filtration, free-standing CNT papers could also be produced [50]. This method is much facile, and the produced CNT papers also exhibit good mechanical properties.…”

Renewable energy has attracted growing attention due to energy crisis and environmental concern. The renewable power is featured by its intermittent and fluctuating nature, which requires large-scale electrical energy storage devices for dispatch and integration. Among the current energy storage technologies (e.g., pumped hydro, flywheel, compressed air, superconducting magnet, electrochemical systems), electrochemical storage technologies or batteries that reversely convert electrical energy into chemical energy demonstrate extremely great potential in the stationary and transportation applications. Scale determines the device type. Redox flow batteries (RFBs), as one of the large-scale types, are capable of complying with power station. Meanwhile, portable smart electronic devices promote the development of small-scale energy storage systems, such as Li-ion batteries and supercapacitors. With delicate device configuration, materials play critical roles on pursuing advancing performance, in terms of electrode, current collector, and separator. Carbon nanotube (CNT)/polymer composites exhibit promising potentials in the above key entities, which integrate the merits of conductivity, mechanical strength, flexibility, and cost. Therefore, this chapter is devoted to the design and application of carbon nanotube/polymer composites in different kinds of energy storage systems.
