Flexible supercapacitors (SCs) with compact configuration are ideal energy storage devices for portable electronics, owing to their original advantages (e.g., fast charging/discharging). To effectively reduce the volume of SCs, an integrated electrode of free-standing polyaniline (PANI)/single-wall carbon nanotube (SWCNT) film with high performance has been developed via a facile solution deposition method, which can be employed as current collector and active material in the meantime. Thanks to the strong π–π interactions between PANI and CNTs, an efficient conductive network with ordered PANI molecular chains is formed in this hybrid film electrode, which is beneficial for the ion diffusion process and fast redox reaction resulting in a high capacitance of 446 F g–1 and outstanding cycling stability, achieving 98% retention over 13 000 cycles. Predictably, solid-state SCs constructed by this free-standing PANI/SWCNT film electrode exhibited remarkable mechanical stability and flexibility in a compact configuration, let alone its excellent capacitive performance (218 F g–1). Moreover, the highest energy density of flexible solid-state SC reached 19.45 Wh kg–1 at a power density of 320.5 W kg–1, further indicating a good potential as an energy storage device. This work would inspire other simple process techniques for high-performance flexible SCs, catering to the demand of portable electronic devices.

自由站式聚苯胺/ SWCNT膜作为集成电极的柔性超级电容器应用的便捷处理
紧凑的柔性超级电容器（SC）凭借其最初的优势（例如，快速充电/放电），成为便携式电子产品的理想储能设备。为了有效地减少SC的体积，已经通过一种简便的溶液沉积方法开发了一种高性能的独立式聚苯胺（PANI）/单壁碳纳米管（SWCNT）薄膜的集成电极，该电极可以用作集电器和在此期间，活性物质。由于PANI和CNT之间的强π-π相互作用，在此杂化膜电极中形成了具有有序PANI分子链的高效导电网络，这对离子扩散过程和快速的氧化还原反应有利，从而产生了446 F的高电容g –1出色的循环稳定性，在13 000次循环中保持98％的保留率。可以预见，由这种独立的PANI / SWCNT薄膜电极构成的固态SC在紧凑的配置中显示出显着的机械稳定性和柔韧性，更不用说其出色的电容性能（218 F g –1）。此外，灵活的固态SC最高能量密度达到19.45瓦千克-1在320.5千克w ^的功率密度-1，进一步指示良好潜力作为能量存储装置。这项工作将激发出针对高性能柔性SC的其他简单处理技术，以满足便携式电子设备的需求。
