新型锂电池隔膜专利技术分析

Patent Technology Analysis of New Lithium Battery Separator

从全球专利申请趋势、全球专利申请地域分布、全球重点申请人以及全球专利申请技术主题四个不同角度分析了全球新型锂电池隔膜的专利技术信息,2016年之后,该领域专利量呈快速增长趋势。中国主要技术输出国以及专利布局国,在新型锂电池隔膜领域占据绝对的技术优势,国内广东省、江苏省以及浙江省是该领域研究的主要省份区域,中国的知名企业冠力新材料、厚生新能源是该领域主要申请人。聚偏氟乙烯类是新型锂电池隔膜是技术研究热点,聚酯类、聚酰亚胺类锂电池隔膜同样发展迅速,纤维类的技术研究一直平稳缓慢发展。

This paper analyzes the patent technical information of global new lithium battery separator from four different angles:global patent application trend,global patent application geographical distribution,global key applicants and global patent application technical topics.After 2016,the number of patents in this field shows a rapid growth trend.China's major technology exporting countries and patent distribution countries occupy absolute technical advantages in the field of new lithium battery separator.Guangdong Province,Jiangsu Province and Zhejiang Province are the main provinces and regions in this field.China's well-known enterprises Guanli new materials and Housheng new energy are the main applicants in this field.Polyvinylidene fluoride is a new type of lithium battery separator and a hot spot in technical research.Polyester and polyimide lithium battery separators are also developing rapidly,and the technical research of fiber has been developing steadily and slowly.
