摘要/Abstract

摘要：

随着能源存储技术的创新，新型储能技术已成为构建创新电力系统的关键技术，并为实现碳达峰和碳中和目标提供了重要支撑。因此，为了解包括电化学储能、压缩空气储能、氢储能等在内的新型储能技术的发展趋势和研究现状，本文基于新型储能技术领域专利数据，全面探讨了国内新型储能技术的发展。主要围绕基于LDA主题模型的细分领域展开讨论，涵盖了专利年限、申请地域、申请人单位、合作关系等方面的分析，并深入探究了全球新型储能技术的现状与趋势。结果表明，新型储能技术发展及应用总体上呈快速增长趋势，且中国在新型储能技术领域占据全球的重要份额。在中国专利领域，锂离子电池和超级电容器占据主导地位，表现出强劲的发展势头。压缩空气储能、氢储能、液态金属电池、水系电池等各类储能技术蓬勃发展。中国新型储能技术专利的申请主要集中在经济发达的省份或直辖市，如广东、江苏、北京、浙江等地。各地的重点研究领域有所不同，但申请单位都主要以高校和新能源领域的私企为主。基于上述发现，提出了未来新型储能技术仍需主要研发单位引领边远地区协统发展，高校与企业建立更为紧密的合作关系，共同推动新型储能技术产学研一体化发展。

Abstract:

The advent of new energy storage technologies has identified them as key components for shaping innovative power systems, which are essential in achieving carbon peak and carbon neutrality goals. This paper leverages patent data to explore the developmental trends and research status of emerging energy storage technologies in China, including electrochemical, compressed air, and hydrogen energy storage. It primarily examines subfields using the LDA topic model and offers detailed analyses of patent durations, regional patterns in patent applications, applicant units, and collaboration relationships. Moreover, it assesses the global status and trends of these technologies. The findings reveal a rapid growth trend in the development and application of emerging energy storage technologies, with China emerging as a global leader. In the realm of Chinese patents, lithium-ion batteries and supercapacitors demonstrate significant growth, alongside other flourishing technologies such as compressed air and hydrogen energy storage, liquid metal batteries, and aqueous batteries. Patent applications are predominantly filed in economically developed regions like Guangdong, Jiangsu, Beijing, and Zhejiang. While regional focuses vary, the majority of applications originate from universities and private enterprises specializing in new energy. Based on these insights, it is recommended that future advancements in emerging energy storage technologies be led by major research entities to enhance coordinated development in less developed areas. Strengthening partnerships between universities and private enterprises is also vital for driving the integrated progress of these technologies across academia, industry, and research sectors.
