“…The addition of GPLs particles after 0.1 wt.% in the epoxy resin made a reverse effect with the enhancement of damping factor which is attributed to the agglomeration of the GPL nanoparticles in the epoxy matrix due to their high aspect ratio. 65 As shown in Figure 7, the natural frequency and damping factor of pure CBFE intra-ply hybrid composite in Free-Free boundary condition are measured as 277.5 Hz and 184, respectively. By dispersion of 0.1 and 0.5 wt.% of CNT nanoparticles in the matrix of composite, 6% increase and 3% decrease are occurred in the natural frequency and damping factor, respectively.…”

In this study, effects of addition of carbon nanotubes (CNTs) and graphene platelets (GPLs) on characteristics of carbon/basalt fiber reinforced intra-ply hybrid composites were investigated. The composites were fabricated using vacuum assisted resin infusion molding (VARIM) method in two types including bare and 0.1, 0.5 wt.% of GPL and CNT nanoparticles filled hybrid composites. Fabricated normal and multiscale composites were cut by water jet and mechanical properties of specimens were examined by tensile, flexural, SBS experiments. Therefore, the modulus of elasticity, flexural modulus, tensile and flexural strength and ILSS of bare and multiscale composites were compared. Thermomechanical properties of fabricated composites were evaluated by dynamic mechanic analyze (DMA), thermogravimetric analyze (TGA) and thermal conductivity (TC) tests and storage modulus, loss modulus, damping ratio, glass transition temperature, weight loss and derivative weight loss were compared in fabricated normal and multiscale composites. Similarly, modal properties of fabricated composites such as natural frequency and damping factor were obtained by vibrational tests and compared in fabricated composites. According to the results, the addition of carbon-based nanoparticles improved the characteristics of carbon/basalt fiber intra-ply hybrid composites.The response of composites was directly proportional to the addition ratio of the carbon-based nanoparticles.

“…In most LSBs, Li is used as the anode because of its high theoretical speci c capacity (3860 mAh/g), high Li-ion supply, low density (0.59 g/cm), and low negative electrochemical potential (− 3.040 V vs. the standard hydrogen electrode) 14,15 . However, the use of Li generates safety concerns regarding the formation of Li dendrites.…”

Demand for high-capacity batteries with long cycle life and safety has been increasing owing to the expanding mid-to-large battery market. Li–S batteries are suitable energy-storage devices because of their reversibility, high theoretical capacity, and inexpensive construction materials. However, their performance is limited by various factors, including the shuttle effect and dendrite growth at the anode. Here, an integrated electrode for use in all-solid-state (ASS) Li–S batteries was formed via hot-pressing. In detail, S particles dispersed in a functionalized reduced graphite oxide (rGO) cathode with a binder-less polymer electrolyte (PE) and a dual-anion ionic liquid-containing cross-linked poly(ethylene oxide)–Li bis(fluoromethanesulfonyl)imide–N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide-based solid polymer electrolyte (SPE, PEO–LiFSI0.1(Pyr14TFSI)0.4) were hot-pressed into an integrated electrode, serving as both the cathode and electrolyte. The resultant S/rGO-based solid-state Li–S batteries exhibited more stable performance than Li–S batteries using liquid electrolytes, indicating that the dual-anion SPE layer effectively suppressed the dendritic L formation and the shuttle effect with high ionic conductivity. At 0.1 C, the battery discharge capacities were 957 and 576 mAh g− 1 in the first cycle and after 100 cycles, respectively. At 1 C, the reversible capacity was 590 and 417 mAh g− 1 in the first cycle and after 100 cycles, respectively (capacity retention = 71%). Therefore, the proposed S/rGO/PE//LiFSI0.1(Pyr14TFSI)0.4-integrated electrodes are beneficial for ASS Li–S batteries.

“…40 Wang et al prepared a multi-channel porous structured nanofiber with lotus root-like walls by etching using SiO 2 as a pore-forming template. 41 However, all the embedded sulfur content lacks sufficient electron pathways inside the hollow structure, which lead to sluggish kinetics and a low sulfur utilization ratio for low capacity. Therefore, challenges still remain for hollow carbon nanofiber hosts to achieve high sulfur loading (high energy density) without sacrificing cycling stability.…”
