2.3 Printing technology
In order to realize the rapid commercial application of flexible
electronic devices, mature printed electronic technology has received
widespread attention. Printed electronics provides a simple, efficient
and environmentally friendly manufacturing technology for the design of
flexible supercapacitors. It has been widely developed in the field of
flexible supercapacitors and has shown great potential. As a common
printing substrate in daily life, paper is naturally favored by the
majority of scientists. At present, a variety of printing technologies,
including screen printing, inkjet printing, coating, writing and 3D
printing, are used to prepare paper-based supercapacitors. This section
summarizes the development of printing technology in paper-based
supercapacitors. Table 3 summarizes the performance parameters of
cellulose paper-based electrodes prepared by different printing
technologies, so that readers can intuitively understand the application
of this technology in the field of paper-based supercapacitors.
