全球新型储能技术发展态势分析

International Development Trend Analysis of New Energy Storage Technologies

  • 摘要: 在落实“碳达峰、碳中和”目标过程中,储能对支撑以新能源为主体的新型电力系统负荷平衡起到重要作用,新型储能技术因建设周期短、选址灵活性高、调节能力强等优势受到更多关注。对比梳理了美国、欧盟、日本等主要国家/地区新型储能技术战略规划布局情况。针对新型储能技术中锂离子电池、钠离子电池、液流电池、金属空气电池、压缩空气储能、重力储能六大技术方向,利用文献计量和专利计量方法深度挖掘分析了国内外在该领域的前沿主题与创新能力。结果显示,中国在新型储能技术领域研发创新能力整体较强。从论文成果统计来看,中国在该技术领域发表超过70 000篇论文,位居全球首位,占全球发文总量的53.5%。从专利成果统计来看,中国是2020—2022年间新型储能领域最重要的专利技术来源国,发明专利及高价值专利申请数量占比均超过全球80%以上,但高价值专利产出率略低于全球平均水平。

     

    Abstract: In the process of implementing the “dual-carbon”goal, energy storage plays an important role in supporting the load balance of new power systems mainly based on new energy sources, and new energy storage technologies have been receiving more attention due to their advantages of short construction period, high flexibility in siting, and strong regulating capability. This paper compares and analyzes the strategic planning layout of new energy storage technologies in major countries/regions such as the United States, the European Union, and Japan. For the six major technology directions of new energy storage technology, namely lithium-ion battery,sodium-ion battery, liquid flow battery, metal-air battery,compressed air energy storage, and gravity energy storage, the literature measurement and patent measurement methods are utilized to deeply excavate and analyze the cutting-edge themes and innovation ability in this field at home and abroad. The results show that China’s R&D and innovation ability in the field of new energy storage technology is overall strong. From the statistics of paper achievements, China has published more than 70,000 papers in this technology field, ranking first in the world,accounting for 53.5% of the total number of papers published in the world. From the statistics of patent achievements, China has been the most important source country of patented technology in the field of new energy storage from 2020 to 2022, and the number of invention patents and high-value patent applications accounted for more than 80% of the global total, but the output rate of high-value patents is slightly lower than the global average level.
