Abstract

Abstract

Recently, micro-supercapacitors (MSCs) have undergone major development as next-generation micro-electrochemical energy storage devices for self-powered, integrated, and wearable systems, thanks to their excellent performance capability. In particular, their rapid frequency response characteristics make them potential candidates to replace conventional capacitors and function as alternating current (AC) line filters to rectify pulse energy or as current ripple filters in the kHz range. However, few papers have been published about the associated fundamental device components, architectures, and correct characterization of MSCs applied in filter applications. In addition, it is a huge challenge to achieve a balance between capacitance and frequency response, not yet to be overcome. This review comprehensively summarizes recent advances in MSCs for AC line-filtering, from fundamental mechanisms to appropriate characterization and emerging applications. Special attention is given to progress in microfabrication strategies, electrode materials, and electrolytes for high-frequency MSCs. We also present perspectives and insights into the development of MSCs in different frequency ranges for AC line-filtering applications.

● The fundamental introduction and performance evaluation specification of MSCs as FCs are given out in detail.
● The key challenges and possible approaches for achieving highperformance MSCs as FCs are discussed according to frequency regions.
● The different electrolytes are discussed to clarify their influence on MSCs in voltage windows and frequency characteristics.
● The various electrode structures and their advantages are analyzed to ensure the rapid response, where the highly ordered materials are most desirable for high-frequency MSCs.
