Carbonized cotton fibers (CCFs) were prepared by the carbonization of commercial cottons at 700, 800 and 900 °C. The following characterizations indicated that the properties of the obtained CCFs could be effectively tuned by the carbonization temperatures. Containing both high conductivity and high aspect ratio, the CCFs could be used as the conductive agents for the construction of the integrated organic cathodes in lithium ion batteries (LIBs). With the optimized ratio of CCF from 900 °C, the organic LIB cathodes showed a high specific capacity of 135 mA h g⁻¹ at a current density of 0.05 A g⁻¹ and an impressive cyclizing stability by keeping 90.5% of the highest capacity value after 500 cycles at 0.5 A g⁻¹. The moderate mechanical stability of the CCF supported organic cathode enabled the further fabrication of flexible LIBs, which manifested stable performances at various bent states, confirming the potentials of CCFs in flexible energy storage devices.

碳化棉纤维（CCFs）是通过在700、800和900°C下碳化商品棉而制备的。以下特征表明，可以通过碳化温度有效地调节所获得的CCF的性质。CCF既包含高导电率又具有高纵横比，可以用作构建锂离子电池（LIB）中集成有机阴极的导电剂。通过从900°C开始优化的CCF比，有机LIB阴极在0.05 A g ^-1的电流密度下显示出135 mA h g ^-1的高比容量，并通过保持最高容量值的90.5％表现出令人印象深刻的成环稳定性。在0.5 A g ^-1下500次循环后。CCF负载的有机阴极的适度机械稳定性使柔性LIB的进一步制造成为可能，该LIB在各种弯曲状态下均表现出稳定的性能，证实了CCF在柔性储能装置中的潜力。
