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.
