摘要
液流电池技术作为一种大规模高效电化学储能技术,具备寿命长、安全可靠等突出优势。本工作以液流电池技术为研究对象,通过对液流电池技术相关专利的分析,揭示该技术领域研发和专利申请活动的特点,为我国在这一具有战略重要性的储能技术领域中的研发和产业化提供知识产权情报支撑。在调研液流电池技术研发概况的基础上,利用Derwent Innovations Index(DII)数据库检索液流电池相关专利信息,并使用TDA、Innography等分析工具,从专利申请数量的年度变化趋势、技术研发主题、主要竞争国家/地区、主要专利申请人等方面,对全球液流电池技术的整体专利态势进行了分析。结果发现,日本在该技术领域处于全球领先地位,近年来全球液流电池的专利申请数量呈现爆发式增长,并开始走向商业化应用。
Flow batteries are used mainly for large-scale energy storage,which have a great number of outstanding advantages,including long lifespan and high safe reliability.In order to reveal the development features of this technology and provide intellectual property strategy support for our country,we study the international patents in flow cell technology.The patent information in this article is gathered from the Derwent Innovation Index（DII）.By using the method of literature investigation,we summarize the overview of the flow cell technology development.Then we analyze the trend of the patent application number,the layout of the technology,the situation of patent applications on flow cell in the main countries or regions,and the significant patentees by using the analysis tools—TDA and innography.As a result,we find that Japan takes the lead in this sector,and the dramatic rise in patent application number recently shows the gradually mature of flow cell technology.
