With the rapid development of science and technology, paper-based
functional materials have become the core of the field of new materials.
Recently, they have received extensive attention in the field of energy
storage due to their advantages of rich and adjustable porous network
structure, good flexibility. As an important energy storage device,
paper-based supercapacitors have important application prospects in many
fields, and have also received extensive attention from researchers in
recent years. At present, researchers have modified and regulated
paper-based materials by different means such as structural design and
material composition to enhance their electrochemical storage capacity.
The development of paper-based supercapacitors provides an important
direction for the development of green and sustainable energy.
Therefore, it is of great significance to summarize the relevant work of
paper-based supercapacitors for their rapid development and application.
In this review, the recent research progress of paper-based
supercapacitors based on cellulose was summarized in terms of various
cellulose-based composites, preparation skills and electrochemical
performance. Finally, some opinions on the problems in the development
of this field and the future development trend were proposed. It is
hoped that this review can provide valuable references and ideas for the
rapid development of paper-based energy storage devices.
