摘要
锂硫电池是取代锂离子电池最具竞争力的下一代二次电池之一。文章全面检索了国内外机构在中国申请的锂硫电池专利,并从技术发展趋势、申请地区和国家分布、主要研发机构、技术结构等方面进行了统计分析研究。结果表明:近年来我国锂硫电池专利呈快速增长趋势;但是我国锂硫电池技术还处于研究起步阶段,本土企业申请专利数量极少,企业申请人专利主要来自以韩国三星SDI株式会社为代表的跨国公司;高校科研院所是本土锂硫电池技术的研究主体,如中国科学院、中南大学等;国内锂硫电池的主要研究方向是硫复合正极材料的制备。
Lithium-sulfur battery is one of the most competitive next-generation battery to replace lithium-ion battery.This paper analyzed the technology trends,application areas distribution,the major research institutions and the technical architecture of lithium-sulfur battery technology after a comprehensive retrieval of the Chinese lithium-sulfur battery patent.The results showed that： the lithium-sulfur battery patent showed rapid growth trend nearly six years.Since China＇s lithium-sulfur battery technology is still in its infancy research, there is a few local enterprise applicants, the enterprise applicants are mostly foreign multinationals, Samsung SDI Co., Ltd. from South Korea is a typical example.Universities and research institutes are the research subject of Chinese lithium-sulfur battery technology,Chinese Academy of Sciences,Central South University are typical examples.The main research directions of domestic lithium-sulfur battery is the preparation of sulfur composite cathode material.
