Lithium‑oxygen cells have attracted the significant attention of researchers in recent years due to their extremely high energy density, comparable to the energy density of fossil fuels. However, because of the sluggish kinetics of discharge/charge reactions, the development of lithium‑oxygen technology has been largely limited. One way to tackle this problem is the development of an efficient catalyst for cathode materials that will exhibit high capacities, good rate capabilities, and sufficient stability. Due to their excellent electrochemical properties and controlled porous texture, carbon nanotubes (CNTs) have been one of the candidates for this application. Many methods have been proposed to improve their catalytic activity and, as a result, enhance the performance of lithium‑oxygen cells. These include transition metal coating, precious metal decorating, or heteroatom doping. This review provides an in-depth look at CNT functionalization methods and their impact on nonaqueous lithium‑oxygen cell performance.

锂氧电池由于其极高的能量密度，与化石燃料的能量密度相媲美，近年来引起了研究人员的极大关注。然而，由于放电/充电反应的动力学缓慢，锂氧技术的发展在很大程度上受到了限制。解决这个问题的一种方法是开发一种高效的阴极材料催化剂，该催化剂将表现出高容量、良好的倍率性能和足够的稳定性。由于其优异的电化学性能和可控的多孔结构，碳纳米管 (CNT) 已成为该应用的候选者之一。已经提出了许多方法来提高其催化活性，从而提高锂氧电池的性能。这些包括过渡金属涂层，贵金属装饰或杂原子掺杂。本综述深入探讨了 CNT 功能化方法及其对非水系锂氧电池性能的影响。
