# Application of the Supercapacitor for Energy Storage in China: Role and Strategy
## 4 Strategy and Innovation Status Quo
### Suggestions  
Although supercapacitor have become an indispensable part of hybrid electrochemical energy storage due to its many advantages, such as short-time efficient frequency modulation, long-cycle life, fast charging, etc., they are always overshadowed by batteries. The development of lithium-ion batteries, for example, has been boosted in recent years by heavy government subsidies and investor funding, making it easier to catch the world's attention on international racetracks. In contrast, it is difficult for supercapacitors to obtain strong financial support, and the progress and development of technology has been greatly restricted. Once supercapacitors make a breakthrough in technology, they will greatly promote the development of new energy industry and the achievement of carbon neutrality. The following suggestions are put forward:  
1. 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. As a backward country in the fields of supercapacitors, China is relatively weak in industrial technology research. Only by increasing the financial investment and stimulating the enthusiasm of industrial investment can it catch up with the advanced international level. The development of basic technology is a process of accumulation. The Chinese government should provide long-term investment and support to promote it.  
2. Develop energy storage technology according to practical demand  
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. China should further expand its application based on the actual demand, looking for the motivation and direction in practical application. China has a vast market and opportunities for supercapacitors. Once there is an insatiable demand, it will continue to promote technology and application to a higher level.  
3. Promote the demonstration and commercialization of energy storage technology  
Supercapacitors identified as fast-emerging technologies have already been taken as the key developing field 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. Technology and capital will be guided to the research and application of supercapacitors, and the enterprise-university-institute cooperation will be encouraged and promoted to improve the efficiency in transforming scientific research achievement into production technologies.  
(4) Enhance the cooperation in academic and industrial fields  
The development of the supercapacitor industry grows out of the common progress of theory and applied field, and China has accumulated mature experience in the domestic applied field, which can provide truly valuable research directions. It can also make advanced research results create more kinds of applications. Besides the domestic collaboration, both the academic institutions and industrial enterprises should learn from the advanced technologies and solution of other countries in implementing the energy storage systems, introduce and digest them, and put them into effect by combining the practical demand in China.
