Flexible all-solid-state supercapacitors with high capacitance, long cycle life, and wide operational potential window: Recent progress and future perspectives

Dimensional Nanoarchitectonics of g-C3N4/Co Nanocomposites for Photo- and Electro-Chemical Applications

“…Supercapacitors have been widely studied in the field of energy storage because of their increased power density and cycle stability. − On account of excellent conductivity and special retractable structures, CNTs are widely used in various capacitors. , Samples were prepared into electrodes, and their supercapacitor properties were tested in 3 M KOH solution. Figure a exhibits CV curves of samples at a scan rate of 100 mV/s.…”

Facile Enhancement of Electrochemical Performance of Solid-State Supercapacitor via Atmospheric Plasma Treatment on PVA-Based Gel-Polymer Electrolyte

“…SCs provide several benefits over batteries, such as rapid charge/discharge rates, long-term cyclability, and high power density [ 3 ]. In particular, solid-state supercapacitors (SSCs) are expected to be used in future energy storage devices that are increasingly demanded for flexible, wearable, and portable devices [ 4 ]. An SC typically consists of two electrodes (one positive and one negative), a separator, and an electrolyte [ 5 ].…”

Utilization of compressible hydrogels as electrolyte materials for supercapacitor applications

“…EDLCs store electrical energy by building a double layer at the electrode-electrolyte interface, whereas pseudocapacitors depend on the fast faradaic redox reactions of electroactive species. 4,5,25 Generally, pseudocapacitors have higher capacitance than EDLCs. There are various inorganic metal oxides or hydroxides, for example, CuO, NiO, MnO 2 , RuO 2 , and V 2 O 5 and conducting polymers such as PEDOT, PPy, and PANI that have been tested as electrode materials.…”

“…The rapid development of electronic gadgets such as smartwatches, smartphones, tablets, and laptops demands power sources that can have acceptable mechanical stability, reliability, safety, and environmentally friendly materials; therefore, the development of efficient energy storage (EES) systems becomes signicantly essential to satisfy the above-mentioned requirements. [1][2][3][4] Supercapacitors are always considered strong EES candidates due to their high power density, fast chargedischarge rate, and long cycling stability. 5,6 In addition to these, exible supercapacitors with self-healing properties attract the attention of the research community nowadays because these materials have the potential to quickly restore and effectively maintain the electrochemical performance aer mechanical damage and under various compression or stretching conditions.…”
