“…Specific capacities varied from 254 mAh·g −1 to 59 mAh·g −1 at different C-rates from 0.17C to 1.7C in a staircase manner (Figure 7i), and then the specific capacity was recovered to an initial capacity of~254 mAh·g −1 (at 0.17C) after being subjected to the higher C-rate up to 1.7C. The stable and reversible specific capacities are comparable to other values from free-standing CNT films [13,18,19]. These findings secure the excellent C-rate capability of the flexible LIB anode, largely ascribed to outstanding structural integrity and interfacial bonding strength of 3D CNTs-graphene on PET.…”

“…CNTs have been verified as promising anode nanomaterials due to their excellent electrochemical properties [9][10][11][12][13][14][15][16][17][18][19][20][21]. Our research team recently reported exceptionally high and stable reversible capacities of~900 mAh·g −1 at 372 mA·g −1 or 1C (time for complete discharge in reciprocal hours) from CNTs directly grown on a Cu substrate [22]; we also demonstrated that the atomic layer deposition (ALD) alumina (Al 2 O 3 ) coated CNTs on Cu showed a specific capacity of 1100 mAh·g −1 [23].…”

Carbon nanostructural materials have gained the spotlight as promising anode materials for energy storage; they exhibit unique physico-chemical properties such as large surface area, short Li + ion diffusion length, and high electrical conductivity, in addition to their long-term stability. However, carbon-nanostructured materials have issues with low areal and volumetric densities for the practical applications in electric vehicles, portable electronics, and power grid systems, which demand higher energy and power densities. One approach to overcoming these issues is to design and apply a three-dimensional (3D) electrode accommodating a larger loading amount of active anode materials while facilitating Li + ion diffusion. Furthermore, 3D nanocarbon frameworks can impart a conducting pathway and structural buffer to high-capacity non-carbon nanomaterials, which results in enhanced Li + ion storage capacity. In this paper, we review our recent progress on the design and fabrication of 3D carbon nanostructures, their performance in Li-ion batteries (LIBs), and their implementation into large-scale, lightweight, and flexible LIBs.

“…Films based on lightweight materials, such as carbon nanotubes (CNT) and graphene, have been widely investigated as current collectors for flexible LIB [5,7,14,16]. Yoon et al reported that carbon nanotube films as negative electrodes for flexible LIB had high flexibility, good mechanical properties, and high electrical conductivity [17]. However, these nanostructured current collectors and carbon-based materials are relatively expensive and require complex preparation processes.…”

Flexible, low-weight electrodes with integrated current collectors based on chopped polyacrylonitrile carbon fibers (CF) were produced using an easy, aqueous fabrication process, where only 4 wt% of TEMPO-oxidized cellulose nanofibrils (CNF) were used as the binder. A flexible full cell was assembled based on a LiFePO 4 (LFP) positive electrode with a CF current collector and a current collector-free CF negative electrode. The cell exhibited a stable specific capacity of 121 mAh g −1 based on the LFP weight. The CF in the negative electrode acted simultaneously as active material and current collector, which has a significant positive impact on energy density. Stable specific capacities of the CF/CNF negative electrode of 267 mAh g −1 at 0.1 C and 150 mAh g −1 at 1 C are demonstrated. The LFP/CNF with CF/CNF, as the current collector positive electrode (LFP-CF), exhibited a good rate performance with a capacity of~150 mAh g −1 at 0.1 C and 133 mAh g −1 at 1 C. The polarization of the LFP-CF electrode was similar to that of a commercial Quallion LFP electrode, while much lower compared to a flexible LFP/CNF electrode with Al foil as the current collector. This is ascribed to good contact between the CF and the active material.

In this investigation, multiwalled carbon nanotube (MWCNT) paper consists of MWCNTs and cellulose was fabricated by traditional paper-making method. It was applied directly as negative electrode in°exible lithium ion battery to replace ordinary electrode which is combined with anode material and current collector. The electrochemical performances of the as-produced MWCNT paper (AMP) and carbonized MWCNT paper (CMP) were evaluated in this study. The morphology and structure of the MWCNT papers were observed by scanning electron microscopy (SEM). The electrochemical performance of the battery was operated by cell test and electrochemical impedance spectroscopy (EIS) measurement. The charging and discharging results indicated that the CMP behaves with higher capacity than AMP. And the EIS analysis showed that a lower charge transfer resistance can be obtained in the CMP. The excellent electrochemical performance veri¯es the feasibility of MWCNT papers as a promising candidate for the anode in°exible lithium ion battery.
