摘要
为掌握纯电动车辆用锂离子电池的发展现状,文章基于DI专利数据库、INCOPAT专利数据库对车辆锂离子电池的专利情况进行了深入的分析,多维度揭示国内外发展趋势,总结国家分布,梳理研究热点,指出当前我国纯电动车辆锂离子电池技术产业存在技术发展时间短、领先优势不足、专利国际布局不合理、技术保护有待加强等问题,需要深化企业以及研究机构之间的合作,紧跟国家政策并进行专利预警。
In order to master the development status of lithium-ion batteries for pure electric vehicles,this paper conducts an in-depth analysis of the patent situation of lithium-ion batteries for vehicles based on DI patent database and INCOPAT patent database,reveals the development trend at home and abroad in a multi-dimensional way,summarizes the national distribution,combs out research hotspots,and points out that the current pure electric vehicle lithium-ion battery technology industry in China has such problems as short technology development time,insufficient leading advantages,unreasonable international distribution of patents,and technology protection needs to be strengthened,require deepening cooperation between enterprises and research institutions,closely following national policies,and conducting patent early warnings.
