“…As shown in Figure a–c, the CNT–S, FeOOH/CNT@S-M, and FeOOH/CNT@S-A electrodes at various potentials are carried out, respectively. According to Figure c, the semicircle comes from the high-frequency region, the FeOOH/CNT@S-A electrode shows lower R ct values than the other two electrodes, which is ascribed to the precipitation of solid LiPSs and excellent conductivity of FeOOH/CNT@S-A . The equivalent circuit diagram is displayed in Figure S4.…”

The shuttle effect from the dissolution of intermediate lithium polysulfides in the electrolyte and the poor conductivity of sublimated sulfur hinder the commercialization of lithium–sulfur (Li–S) batteries. A one-step hydrothermal method is used to synthesize a nanorod iron hydroxide/carbon nanotube (FeOOH/CNT) composite. The UV–vis experiment shows that the FeOOH/CNT composite is beneficial to adsorption of the Li2S6 solution, which can be attributed to the strong interaction between the Li2S6 solution and the FeOOH/CNT composite. Meanwhile, the introduction of CNTs facilitates rapid electron transfer, leading to a decreased charge-transfer resistance value of the whole electrode. The FeOOH/CNT@S-M composite was prepared by mixing sulfur particles and the FeOOH/CNT composite with ball milling. Further, the synthesized FeOOH/CNT@S-A provides a strong interaction between the FeOOH/CNT composite and sulfur particles after annealing. The S–O and C–S bonds observed in XPS results further confirmed the strong adsorption ability between the two substances, resulting in a suppressed shuttle effect. Eventually, the FeOOH/CNT@S-A electrode has an initial discharge specific capacity of 1290 mA h g–1 at a current density of 0.1 A g–1. After cycling for 200 cycles, the electrode displays a discharge specific capacity of 742 mA h g–1 (at 1 A g–1) with ∼88.5% capacity retention, revealing its good cycling stability. This work demonstrates the potential application of FeOOH/CNT@S-A composite materials in high-performance Li–S batteries.

“…Fan et al investigated an ACNT/sulfur cathode (ACNT/S) in Li-S batteries, which provided the high ionic and electronic conductivity needed for fast-charging. [37] In the ACNT/S electrode, the low tortuosity contributes to fast and effective ion diffusion, while the highly conductive CNTs ensure ultrafast electron transfer. The ACNT/S cathode delivered a high specific capacity of 894 mAh g −1 in the initial cycle at a current density of 5 C, which remained at 486.1 mAh g −1 after 400 cycles with a capacity decay of 0.1% per cycle.…”

Fast-charging batteries have attracted great attention, and are anticipated to charge electrical vehicles and consumer electronics to full-capacity in several minutes. However, commercial electrode materials in batteries generally have a limited rate performance and are difficult to be used in fast-charging batteries. Designing electrodes with an aligned structure is an effective way to shorten the ion transport path and improve the rate performance of a battery. The excellent electronic conductivity of carbon-based electrodes is another key factor for increasing the rate capability of rechargeable batteries. Therefore, aligned carbon-based electrodes (ACBEs) can significantly improve the power density by combining the advantages of an aligned structure and carbon-based materials. In this review, the mechanism, advantages, and challenges of ACBEs for fast-charging batteries are evaluated, and then the design and preparation methods of ACBEs based on their different dimensions are summarized, and their applications in different batteries are illustrated. Finally, the future development of ACBEs for fast-charging batteries is considered.
