At the two sessions of the National People's Congress in 2025, Premier Li Qiang pointed out in the government work report that in the past year, China's annual output of new energy vehicles exceeded 10 million for the first time, the proportion of renewable energy installed capacity has historically surpassed fossil energy, and the area of planted forests ranks first in the world, becoming the country with the most greenery in the world. From industrial transformation to global cooperation, from carbon reduction and energy conservation to ecological restoration, China has delivered multidimensional and highquality answers to the entire industrial chain of the "energy revolution".

During the "two sessions", relevant proposals on issues such as energy transition and energy cooperation became the focus of attention of all parties. "Sankei Online" combed through the proposals and proposals of the participants and committee members, and noted that the continuous optimization of policies, technological innovation breakthroughs, and continuous expansion of application scenarios will help new energy industries such as photovoltaics, hydrogen energy, and energy storage to advance from highspeed growth to highquality development, and contribute to the majestic "Chinese power" of global green and low-carbon development.

率先探索“锂电+超级电容器”

混合储能调频应用


随着清洁能源迅猛发展,我国电源结构出现了重大变化,据统计,目前风、光等清洁能源累计装机占比超过20%,预计“十四五”将达到40%。而为了保障电网的安全稳定运行,电力系统需要更多的灵活调频资源来提升自身调节能力。国家发展改革委、国家能源局明确要求现有火电机组调节性能改造,提高电力系统灵活性和调节能力,鼓励电源侧、电网侧和用户侧储能应用,鼓励多元化的社会资源投资储能建设。
超级电容器较传统火储调频用的磷酸铁锂电池,有着突出优点:功率密度高、充放电速度快、使用寿命长、高低温性能优越、安全、环保等特性,与储能辅助调频工况十分契合,“磷酸铁锂电池+超级电容器”混合储能的创新技术路线由此诞生。

Broaden the application scenarios
Drive the high-quality development of the supercapacitor industry chain


"As an electrochemical energy storage device, supercapacitors have very obvious advantages over other energybased electrochemical energy storage technologies such as lithium iron phosphate batteries.

Wang Chao, the person in charge of the project of China Southern Power Grid Technology and the thirdlevel leading technical expert of China Southern Power Grid, said that with the increase in the proportion of new energy and the proportion of terminal power in the future, the unbalance between the source and load at both ends will increase the demand of the power grid for flexible frequency modulation resources, which will also open up a broader application market for supercapacitors, and will accelerate the technical iteration and upgrading of supercapacitors and scale improvement, so as to reduce costs and increase efficiency, and bring new qualitative momentum to the supercapacitor industry.
