On April 21, the IEC/TS 62565-5-2 standard issued by the International Electrotechnical Commission (IEC), which was developed under the leadership of the Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences, was officially released. The title of this standard is “Nanomanufacturing – Material Specifications – Part 5-2: Nano-enabled electrodes of electrochemical capacitors – Blank detail specification”. This standard proposal was put forward in 2018, and the project was approved in May 2020. Wang Zhenbing and Chen Chengmeng from the Shanxi Coal Chemistry Research Institute served as the leaders of the project team, while Huang Xianhong acted as the executive coordinator. The team consisted of ten experts from China, Canada, South Korea, Germany, and Russia. During the development process, opinions from IEC member countries were widely sought, which laid the foundation for the high applicability and widespread adoption of this standard. Electrochemical capacitors are widely used in fields such as electric vehicles, high-speed trains, aircraft, photovoltaics, wind power, and electronics, thanks to their ultra-fast charging and discharging capabilities, long cycle life, wide operating temperature range, high safety and reliability, and low maintenance costs. The Shanxi Coal Chemistry Institute has been conducting research on supercapacitors for over a decade, establishing an industrial innovation chain that connects \"materials – devices – applications.\" In the process of developing nanoporous activated carbon materials for domestic use in supercapacitors, the institute set up a pilot-scale testing platform for supercapacitors to evaluate the electrochemical properties of these materials, thereby providing feedback to guide their development, production, and quality control. Researchers at the Shanxi Coal Chemistry Institute have found that the manufacturing process of supercapacitor electrode sheets, along with the key physical and chemical parameters that need to be controlled, not only reflect the properties of the raw materials but also directly determine the performance of the devices. These factors serve as a crucial link between the raw materials and the final devices; therefore, accurate characterization of supercapacitor electrode sheets is essential for the high-quality development of the entire industry chain. At present, there is still a lack of standards for supercapacitor electrode sheets both internationally and domestically, and there is an urgent need for standardized guidelines to provide direction. Based on industry needs, researchers at the Shanxi Coal Chemistry Institute have developed the first material specification standard for supercapacitor electrode sheets through research and development efforts, extensive and in-depth exchanges with the industry, as well as systematic reviews of scientific literature and standard methods. This standard details the key chemical, physical, structural, and electrochemical properties that affect the performance of electrode sheets, along with the corresponding testing methods. The release of this standard will provide guidance for standardizing terminology and concepts related to supercapacitor electrode sheets, regulating production processes, and establishing product specifications. It will also foster technical exchanges and cooperation in related industries, while offering standard-based support for eliminating trade barriers. At the same time, this standard is the first international standard for supercapacitor electrode sheets, filling a gap in international standardization. It also introduced the concept of supercapacitors to IEC/TC113 (the International Electrotechnical Commission’s Technical Committee on Nanoelectrical Products and Systems), initiating standard-setting work in this field by the IEC and enhancing China’s international influence in the field of materials for supercapacitors.
