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.
