Recent Advances of Flexible Electrospun Nanofibers-based Electrodes for Electrochemical Supercapacitors: A Minireview

Abstract

Flexibility has been identified as the most important factor in the foldable or bendable electrochemical supercapacitors (ESs), which include: electrical double-layer capacitors, and pseudo-capacitors. In this minireview, electrospun polymeric nanofibers (PNFs) and carbon nanofibers (CNFs) based composite electrodes for flexible electrochemical supercapacitors are reviewed in detail. During the past three decades, various electrospun composite electrodes have been developed, and their advantages and disadvantages in ESs are discussed through extensive analysis of literature. Additionally, this paper also discusses and predicts some futuristic research directions based on results published in literature. It is no doubt that electrospinning technology will continue to play an important role in flexible supercapacitor technology.
