“…The energy storage mechanism is almost similar to the traditional parallel capacitor; moreover, it can store relatively higher energy on the electrode than the conventional one. 21 Since this process does not include any Faradaic redox reaction, EDLC exhibits excellent stability and a fast charge−discharge rate. The movements of ions that migrate to and from the electrodes lead the storage mechanism to respond rapidly.…”

Energy storage and production is one of the significant issues of the 21st century, motivating the search for new materials for energy storage devices. Supercapacitors (SCs) play a prominent role among the class of energy storage devices and conversion systems since they provide greater specific capacitance, high power density, longer life span, fast charge–discharge rate, excellent circulation feature, low cost, and are safe to use. The selection of electrode material has great importance in the performance of the supercapacitor. Two-dimensional (2D) layered nanomaterials gained much interest in the fabrication of electrode materials due to their unique physicochemical properties. The current review explores the synthesis and application of novel 2D materials, such as graphene, MXene, transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN), carbon nitrides, metal oxides/hydroxides, and black phosphorus (BP), as supercapacitor electrodes in detail.

“…GEL is a special material between liquid and solid, which exhibits the flexibility and stability of solid and the easy diffusion of liquid (Zhi-yu et al, 2019). It has a series of advantages such as a higher ionic conductivity than solid electrolytes and good mechanical and chemical stability, etc., which makes it a promising electrolyte (Batisse and Raymundo-Piñero, 2017; Qin and Panzer, 2017;Hui et al, 2019;Li et al, 2019). Recently, a novel redox-mediated strategy for SCs was reported, which can efficiently increase the ionic conductivity and produce additional capacitance by the quick reversible redox reaction introduced by the redox mediator (Alipoori et al, 2020).…”

“…Supercapacitors (SCs) are a new type of energy storage equipment filling the gap between secondary batteries and traditional capacitors (Hui et al, 2019;Poonam et al, 2019;Zhi-yu et al, 2019;Alipoori et al, 2020;Cheng et al, 2020;Iqbal et al, 2020;Li and Liang, 2020;Mohd Abdah et al, 2020;Panda et al, 2020;Yi et al, 2020). SCs are believed to be one of the most promising candidates due to their fast charging/discharging capability, long cycle life, high power density, and high safety (Zhang W. et al, 2017;Zhang et al, 2018;Afif et al, 2019).…”

Supercapacitors (SCs) have attracted widespread attention due to their short charging/discharging time, long cycle life, and good temperature characteristics. Electrolytes have been considered as a key factor affecting the performance of SCs. They largely determine the energy density based on their decomposition voltage and the power density from their ionic conductivity. In recent years, redox electrolytes obtained a growing interest due to an additional redox activity from electrolytes, which offers an increased charge storage capacity in SCs. This article summarizes the latest progress in the research of redox electrolytes, and focuses on their properties, mechanisms, and applications based on different solvent types available. It also proposes potential solutions for how to effectively increase the energy density of the SCs while maintaining their high power and long life.

Body sensor network is a promising medical technology to address the overwhelming global aging issue, which requires advanced micro power sources with high energy density, long lifetime, small form factor and good biocompatibility. Potential micro power technologies include batteries, fuel cells, energy harvesters and supercapacitors, each of which have their own merits and demerits when applied in the body sensor network. Batteries such as dry battery and Li ion battery are currently the most mature product which has been extensively employed in the body sensor network research, but the improvement of their energy density is relatively sluggish due to the cumbersome material storage. On the contrary, micro fuel cells can achieve much higher energy density because of their lightweight fuel and oxidant, which can be refueled instantly when applied in wearable sensors. For implanted devices, both abiotic and biotic fuel cells can utilize the dissolved glucose in the body fluid as the fuel. As for energy harvesters, they can receive energy from both the external environment such as solar and radiofrequency, and the human body itself such as body heat and motion. Finally, supercapacitor is an effective energy storage component especially for energy harvesters, which can achieve excellent cycle stability.In general, the selection of micro power sources for the body sensor network should consider the specific requirement from the specific sensor node, so that a body sensor network with hybrid power supply is much more reliable than that with single type of energy supply. With the continuous development of different power technologies, the body sensor network is expected to be more lightweight, unobtrusive and reliable, leading to a low-cost and ubiquitous healthcare in the near future.
