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.
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.
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.
With the adjustment of China’s energy structure and the increasing demand for electrochemical storage power stations, the Chinese supercapacitors market has proliferated in the 13th five-year period. From 2015 to 2020, China’s supercapacitor market increased from CNY 6.65 billion to CNY 15.49 billon, with a compound annual growth rate of 18.4%.
They are widely used to improve the reliability and quality of power distribution of the smart grids, which can provide short-term power protection for the impact load of the power system. The paper elaborately summarizes the development status and policies of supercapacitors in China.
Strengthen research on new technologies for supercapacitors materials. The key point to developing supercapacitors is to improve the energy density. In order to enhance the research level in China for SC-related applications, the development of electrode and diaphragm materials must be strengthened.
