A highly electrically conductive film‐type current collector is an essential part of batteries. Apart from the metal‐based current collectors, lightweight and highly conductive carbon materials such as reduced graphene oxide (RGO) and carbon nanotubes (CNTs) show great potential as current collectors. However, traditional RGO manufacturing usually requires a long time and high energy, which decreases the product yielding rate and manufacturing efficiency. Moreover, the performance of the manufactured RGO needs to be further improved. In this work, CNT and GO are evenly mixed into GO‐CNT, which can be directly reduced into RGO‐CNT by Joule heating at 2936 K within less than 1 min. The fabricated RGO‐CNT achieves a high electrical conductivity of 2750 S cm⁻¹, and realizes a 10⁶‐fold increase. The assembled flexible aqueous Al‐ion battery with RGO‐CNT as the current collector exhibits impressive electrochemical performance in terms of superior cycling stability and exceptional rate capability, and excellent mechanical ability regarding the tolerance to mechanical damage such as bending, folding, piercing, and cutting without detrimental consequences.

用于柔性铝离子电池的RGO-CNT混合膜的纳米制造。

高度导电的薄膜型集电器是电池的重要组成部分。除了金属基集电器之外，轻质和高导电性碳材料（如还原氧化石墨烯（RGO）和碳纳米管（CNT））也显示出巨大的集电器潜力。然而，传统的RGO制造通常需要较长的时间和较高的能量，这降低了产品的合格率和制造效率。而且，制造的RGO的性能需要进一步提高。在这项工作中，将CNT和GO均匀混合到GO-CNT中，可以在不到1分钟的时间内通过2936 K的焦耳加热将其直接还原为RGO-CNT。制成的RGO-CNT可实现2750 S cm ^-1的高电导率，并实现10 ⁶增加两倍。以RGO-CNT为集电器的组装式柔性Al-离子水基电池在卓越的循环稳定性和出色的倍率性能方面具有令人印象深刻的电化学性能，并且在抗机械损伤（例如弯曲，折叠，刺穿和弯曲）方面具有出色的机械性能。切割而无不利后果。
