摘要：

以锂离子电池为代表的电化学储能技术当前进入了快速发展期，在我国能源消费结构调整和可再生能源比例提升方面具有重要意义。储能消防技术是锂离子电池储能系统规模化应用的安全保障。为了解储能消防技术的研发现状，本工作以国家知识产权局公布的专利检索与分析系统数据中的储能消防领域专利数据为分析对象，以灭火剂(A62D)、储能用消防装置(A62C)以及储能消防策略和逻辑方法(G06K)为主要内容，探讨了储能消防技术在国内的发展，并从专利年限分布、专利技术分布、专利地域分析及主要申请人4方面进行总结分析。结果表明，储能消防技术及其应用总体呈快速增长态势，其中消防装置研发专利申请占比多，专用灭火剂研发处于高质量发展期，消防机制设计仍处于缓慢增长期。北方地区申请单位以高校和事业单位居多，而南方地区申请单位以商业公司居多，这与电化学储能商业化应用水平是分不开的，总体上储能系统消防技术仍需要主要研发单位的引领探索。可以预见储能系统消防技术专利量仍然会保持发展态势，相关政策及市场结合将持续激发技术研发活力。

Abstract:

Lithium-ion battery energy storage technology is developing rapidly. This development will adjust the Chinese energy consumption structure and increase their renewable energy. Energy storage fire-protection technology is the safety guarantee of electrochemical energy storage technology. To understand the research and development status of energy storage fire-protection technology, the patent data in the field of energy storage fire protection published by the China National Intellectual Property Administration was the object of analysis. This paper explores the domestic development of energy storage fire-protection technology using fire extinguishing agents (A62D), fire-protection devices for energy storage (A62C), and fire-protection strategy and logic method for energy storage (G06K) as the main content. It was analyzed from four aspects: patent year distribution, patent technology distribution, patent region analysis, and main applicants. The results show that the energy storage fire-protection technology and its application follow a rapid growth trend, in which the patent application of the fire-protection devices takes up a large proportion, the research and development of special fire extinguishing agents increases rapidly, and the design of fire-protection strategies and logic methods evolves.Universities and public institutions are the major applicants in northern China; whereas, commercial companies are the major applicants in southern China, which is related to the commercial application level of electrochemical energy storage. The fire-protection technology of energy storage systems still needs to be explored by major research and development units. It can be predicted that the number of fire-protection technology patents for energy storage systems will continue to evolve, and the combination of relevant policies and markets will stimulate the vitality of research and development of the technology.

Key words: electrochemical energy storage, patent, lithium-ion battery, fire protection technology
