Supercapatteries as Hybrid Electrochemical Energy Storage Devices: Current Status and Future Prospects

Molecules, Journal Year: 2024, Volume and Issue: 29(1), P. 243 - 243

Published: Jan. 2, 2024

Among electrochemical energy storage (EES) technologies, rechargeable batteries (RBs) and supercapacitors (SCs) are the two most desired candidates for powering a range of electrical electronic devices. The RB operates on Faradaic processes, whereas underlying mechanisms SCs vary, as non-Faradaic in double-layer capacitors (EDLCs), at surface electrodes pseudo-capacitors (PCs), combination both hybrid (HSCs). EDLCs offer high power density but low density. HSCs take advantage process without compromising their capacitive nature. Unlike batteries, provide numerous charge–discharge cycles; however, lags that batteries. Supercapatteries, generic term refers to EES devices combine merits RBs, have emerged, bridging gap between RBs. There articles reviews EES, many those emphasized various aspects supercapatteries. However, there no recent dealt with supercapatteries general. Here, we review recently published critically selected discusses different how from others. Also discussed properties, design strategies, future perspectives

The Mass-Balancing between Positive and Negative Electrodes for Optimizing Energy Density of Supercapacitors

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(21), P. 14369 - 14385

Published: May 8, 2024

Supercapacitors (SCs) are some of the most promising energy storage devices, but their low density is one main weakness. Over decades, superior electrode materials and suitable electrolytes have been widely developed to enhance ability SCs. Particularly, constructing asymmetric supercapacitors (ASCs) can extend electrochemical stable voltage windows (ESVWs) thus achieve high density. However, only full utilization potential (ESPWs) both positive negative electrodes endow ASC devices with a maximum ESVW by using mass-ratio between two (the mass-balancing). Nevertheless, insufficient attention directed mass-balancing, even numerous misunderstandings misuses appeared. Therefore, in this Perspective, we focus on mass-balancing: summarize theoretic basis derive relevant relation equations, analyze discuss change trends specific capacitance ASCs mass-ratios, finally recommend guidelines for normative implementation mass-balancing. Especially, issues related pseudocapacitive materials, hybrid different open circuit potentials (OCPs) mass-balancing included emphasized. These analyses be conducive understanding performing developing high-performance
