用于超级电容器的纳米多孔集流体是通过交叉堆叠超排列碳纳米管（SACNT）薄膜制造的，作为重型传统金属集流体的替代品。碳纳米管薄膜集流体具有良好的导电性、极低的密度（27 µg cm - 2）、高比表面积、优异的柔韧性和良好的电化学稳定性。 NiO、Co3O4 或 Mn2O3 纳米颗粒等纳米活性材料可以通过简单的一步原位分解策略直接在 SACNT 薄膜上合成，该策略既高效又环保。这些复合薄膜可以集成到不使用金属集流体的赝电容器中，但仍然表现出非常好的性能，包括高比电容（∼500 F g - 1，包括集流体质量）、可靠的电化学稳定性（2500次循环中退化<4.5%）和非常高的倍率性能（155 A g - 1时为245 F g - 1）。
Nanoporous current collectors for supercapacitors have been fabricated by cross-stacking super-aligned carbon nanotube (SACNT) films as a replacement for heavy conventional metallic current collectors. The CNT-film current collectors have good conductivity, extremely low density (27 µg cm − 2), high specific surface area, excellent flexibility and good electrochemical stability. Nanosized active materials such as NiO, Co3O4 or Mn2O3 nanoparticles can be directly synthesized on the SACNT films by a straightforward one-step, in situ decomposition strategy that is both efficient and environmentally friendly. These composite films can be integrated into a pseudo-capacitor that does not use metallic current collectors, but nevertheless shows very good performance, including high specific capacitance (∼500 F g − 1, including the current collector mass), reliable electrochemical stability (<4.5% degradation in 2500 cycles) and a very high rate capability (245 F g − 1 at 155 A g − 1).
