“…The heat treatment process was continued at 350 °C for 2 h. Oxidation continued after the purification process. Concerning the use of CNTs as reinforcements in composite materials, the incorporation of oxygen-containing functionalities onto the graphitic surface is crucial for improving interfacial adhesion, i.e., the unique mechanical and electrical properties of CNTs can be transferred to the properties of CNT-based composites [ 14 , 15 ]. The oxidation process begins after the purification process.…”

“…Subsequently, the resulting product was filtered and later dried for 24 h at room temperature. The next day, the resulting product was peeled off from the filtration membrane, and the resulting product is called buckypaper [ 14 , 15 ]. The thickness of the experimental buckypaper was adjusted to 17 μm, and the density was around 2.8 g cm −1 .…”

“…The oxidized MWCNTs were dried in an oven at 60 • C for 24 h. The oxidized MWCNTs were subsequently dispersed in water, first by magnetic stirring for 1 h, followed by an ultrasonic bath for 3 h. To obtain a dense structure of MWCNTs, MWCNT dispersion was performed without heating, and the experimental temperature was con-trolled up to 25 • C. Subsequently, the resulting product was filtered and later dried for 24 h at room temperature. The next day, the resulting product was peeled off from the filtration membrane, and the resulting product is called buckypaper [14,15]. The thickness of the experimental buckypaper was adjusted to 17 µm, and the density was around 2.8 g cm −1 .…”

Recently, applications for lithium-ion batteries (LIBs) have expanded to include electric vehicles and electric energy storage systems, extending beyond power sources for portable electronic devices. The power sources of these flexible electronic devices require the creation of thin, light, and flexible power supply devices such as flexile electrolytes/insulators, electrode materials, current collectors, and batteries that play an important role in packaging. Demand will require the progress of modern electrode materials with high capacity, rate capability, cycle stability, electrical conductivity, and mechanical flexibility for the time to come. The integration of high electrical conductivity and flexible buckypaper (oxidized Multi-walled carbon nanotubes (MWCNTs) film) and high theoretical capacity silicon materials are effective for obtaining superior high-energy-density and flexible electrode materials. Therefore, this study focuses on improving the high-capacity, capability-cycling stability of the thin-film Si buckypaper free-standing electrodes for lightweight and flexible energy-supply devices. First, buckypaper (oxidized MWCNTs) was prepared by assembling a free stand-alone electrode, and electrical conductivity tests confirmed that the buckypaper has sufficient electrical conductivity (10−4(S m−1) in LIBs) to operate simultaneously with a current collector. Subsequently, silicon was deposited on the buckypaper via magnetron sputtering. Next, the thin-film Si buckypaper freestanding electrodes were heat-treated at 600 °C in a vacuum, which improved their electrochemical performance significantly. Electrochemical results demonstrated that the electrode capacity can be increased by 27/26 and 95/93 μAh in unheated and heated buckypaper current collectors, respectively. The measured discharge/charge capacities of the USi_HBP electrode were 108/106 μAh after 100 cycles, corresponding to a Coulombic efficiency of 98.1%, whereas the HSi_HBP electrode indicated a discharge/charge capacity of 193/192 μAh at the 100th cycle, corresponding to a capacity retention of 99.5%. In particular, the HSi_HBP electrode can decrease the capacity by less than 1.5% compared with the value of the first cycle after 100 cycles, demonstrating excellent electrochemical stability.

“…However, the wet method, where BPs are made by ltrating CNT solutions through porous membranes, is more widely used owing to its simplicity and easy operation, and the product structure can be well predicted and controlled. 9 A uniform CNT dispersion is essential and of great necessity in making high-performance BP lms via wet method. Thus, the selection of appropriate dispersant and dispersing media to prepare the CNT suspension becomes a crucial step of the process.…”
