In search of affordable, flexible, lightweight, efficient and stable supercapacitors, metal oxides have been shown to provide high charge storage capacity but with poor cyclic stability due to structural damage occurring during the redox process. Here, we develop an efficient flexible supercapacitor obtained by carbonizing abundantly available and recyclable jute. The active material was synthesized from jute by a facile hydrothermal method and its electrochemical performance was further enhanced by chemical activation. Specific capacitance of 408 F/g at 1 mV/s using CV and 185 F/g at 500 mA/g using charge-discharge measurements with excellent flexibility (~100% retention in charge storage capacity on bending) were observed. The cyclic stability test confirmed no loss in the charge storage capacity of the electrode even after 5,000 charge-discharge measurements. In addition, a supercapacitor device fabricated using this carbonized jute showed promising specific capacitance of about 51 F/g, and improvement of over 60% in the charge storage capacity on increasing temperature from 5 to 75 °C. Based on these results, we propose that recycled jute should be considered for fabrication of high-performance flexible energy storage devices at extremely low cost.

“…Composite yarns based on polymer and carbon or/and metal oxide have been prepared by a number of approaches and exhibit advanced electrochemical performances. [507][508][509] Fiber SCs based on CNTs and PANi composites have superior properties to those based on pure CNTs. Moreover, the as-prepared yarns can be woven into wearable electronics due to their excellent mechanical performance.…”

With the development of renewable energy and electrified transportation, electrochemical energy storage will be more urgent in the future. Supercapacitors have received extensive attention due to their high power density, fast charge and discharge rates, and long‐term cycling stability. During past five years, supercapacitors have been boomed benefited from the development of nanostructured materials synthesis and the promoted innovation of devices construction. In this review, we have summarized the current state‐of‐the‐art development on the fabrication of high‐performance supercapacitors. From the electrode material perspective, a variety of materials have been explored for advanced electrode materials with smart material‐design strategies such as carbonaceous materials, metal compounds and conducting polymers. Proper nanostructures are engineered to provide sufficient electroactive sites and enhance the kinetics of ion and electron transport. Besides, new‐concept supercapacitors have been developed for practical application. Microsupercapacitors and fiber supercapacitors have been explored for portable and compact electronic devices. Subsequently, we have introduced Li‐/Na‐ion supercapacitors composed of battery‐type electrodes and capacitor‐type electrode. Integrated energy devices are also explored by incorporating supercapacitors with energy conversion systems for sustainable energy storage. In brief, this review provides a comprehensive summary of recent progress on electrode materials design and burgeoning devices constructions for high‐performance supercapacitors.

“…[ 10,11,[15][16][17][18][19][20] Other precursors such as polymers have also been used to obtain mesoporous carbons with specifi c architectures for charge storage applications. [21][22][23][24] Since carbohydrates have carbon as their primary constituent, a carbohydrate containing biomass is a very good inexpensive source of functional carbon. Also, the presence of inorganic minerals such as potassium and calcium therein can be advantageous in the creation of porosity in the carbon synthesized using such precursors via pyrolysis.…”

not well-suited with the planar geometry of most electronic devices. Hence, planar interdigitated microscale charge storage devices are gaining importance over conventional fl ip-chip devices. [1][2][3] Fabrication of such microscale electronic devices is a major challenge because the methods used have to be facile, effi cient, and compatible with those used in the other fl exible device fabrication protocols. Various techniques such as lithography, physical vapor deposition using shadow mask, sputtering, laser writing, etc., have been used to fabricate planar interdigitated microsupercapacitors till date. [4][5][6] Except the laser-based methods most other methods are somewhat complicated or time consuming. Of course, they do have specifi c advantages of concurrent wafer scale processing and scalability that cannot be underplayed. Laser-based device fabrication methods are however mostly single step, simple, and fast. Most of these have used laser power for the synthesis or direct writing of conducting carbon. [7][8][9] In this paper, we report an even simpler and faster method of device fabrication using fast CO 2 laser scribing of a layer of mushroom-synthesized conducting carbon to fabricate a planar microsupercapacitor on a fl exible substrate. This approach can be easily extended to other presynthesized forms of carbon for electrochemical doublelayer capacitors (EDLCs) or metal oxides/sulfi des for pseudocapacitors. We also point out that the mushroom-synthesized carbon in our case is formed by using a specifi c hydrothermal preprocessing protocol not used before and naturally renders few layer graphene-graphitic composite that offers the concurrent advantage of fl exibility and high conductivity. Mushroom has been used earlier as a precursor for carbon synthesis [ 10,11 ] but in these works precarbonization at low temperature of 500 °C was employed instead of hydrothermal preprocessing (used in the present work) before activation.Flexible planar microsupercapacitors have some serious issues like low energy density and low stability that limit its practical application. To improve the device performance, the quality of the electrode plays a signifi cant role. It has been reported that mesoporous carbon-based electrodes in EDLCs show great promise for microsupercapacitors both in terms of stability and energy density. [ 12 ] This type of material also offers A report is presented on the fabrication of all solid-state interdigitated fl exible microsupercapacitor using ultrafast and highly scalable laser scribing technique, using highly mesoporous carbon synthesized from biomass (mushroom) with hydrothermal preprocessing. The specifi c protocol used for carbon synthesis renders some unique property features to the material (surface area of 2604 m² g −1 with hierarchical pore size distribution) in the context of supercapacitor electrode application. A polyvinyl alcohol (PVA)-H 2 SO 4 gel electrolyte is used for electrochemical measurements. The microsupercapacitor shows high cyclic stability up to 15000 cycles....
