英文摘要	successful application of inexpensive energy storage devices lies in the exploitation of fabrication approaches that are based on cost-efficient materials and that can be easily scaled up. here, inexpensive textile weaved by natural flax fiber is selected as raw material in preparing flexible and binder-free electrode material for supercapacitors. although carbon fiber cloth obtained from the direct carbonization of flax textile exhibits a low specific capacitance of 0.78 f g(-1), carbon fiber cloth electrode shows a very short relaxation time of 39.1 m s and good stability with almost 100% capacitance retaining after 104 cycles at 5 a g(-1). to extend the application of the resulting carbon cloth in supercapacitor field, a layer of mno2 nanosheets is deposited on the surface of carbon fiber via in situ redox reaction between carbon and kmno4. the specific capacitance of mno2 reaches 683.73 f g(-1) at 2 a g(-1) and still retains 269.04 f g(-1) at 300 a g(-1), indicating the excellent rate capacitance performance of the carbon cloth/mno2 hybrids. the present study shows that carbon cloth derived from flax textile can provide a low-cost material platform for the facile, cost-efficient and large scale fabrication of binder-free electrode materials for energy storage devices.
