Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The consumption of supercapacitors in transportation and industry accounts for 38.2% and 30.8%, respectively, that of new energy accounted for 21.8%, and that of equipment and other applications accounts for 9.2%. Figure 5. (a) Application field of supercapacitor. (b) Market segment capacity of supercapacitor from 2018 to 2020 in China.
To improve the energy storage capacity of ceramic capacitors and promote their application in more environments and a wider range, ceramic powders with such local polymorphic polarization configuration were selected to prepare MLCC prototype devices by tape-casting process and screen-printing technique.
The Chinese government should provide long-term investment and support to promote it. The application of supercapacitors in the energy storage system is still in the stage of development. Some applications, especially for electric power systems, still have great potential to achieve large-scale development in the future.
In terms of policy support, China’s incentive measures for supercapacitors are in their infancy, whether it is national key R&D projects or funding from local government. Measures should be taken to ensure the effective development of the energy storage industry, especially to the whole industrial chain of supercapacitors.
In the future, with the reform of China’s energy framework, supercapacitors will be in an irreplaceable position for new energy. Figure 9. (a) Patent application trend in the field of supercapacitors. (b) Distribution of patent application country (region). (c) China supercapacitors market size forecast (CNY 100 million).
