摘要
【目的】以专利数据为基础,融合产业、市场、政策等信息对锂离子电池隔膜的发展态势进行具体分析,明晰天津市锂离子电池隔膜产业的定位,为相关产业发展提供决策参考。【方法】结合研究需要,绘制主要专利分析指标图表,可视化展示相关指标状况与趋势。【结果】通过对图表的分析与解读,对天津市锂离子电池隔膜领域的专利申请趋势、地域分布、主要申请人、技术分布等维度信息统计分析。【结论】当前天津市本土锂离子电池隔膜产业总体偏弱,还需加强领域内本地优势企业培育引进,各高校、科研院所在新研发上也需积极探索。
[Purposes]The development situation of lithium-ion battery separator is specifically analyzed based on patent data integrating industry,market,policy and other information,which clarifies the posi-tioning of the lithium-ion battery separator industry in Tianjin and provides decision-making reference for the development of the industry.[Methods]Combining with the research needs,this paper draws the charts of the main patent analysis indicators to visualize the status and trend of the relevant indicators.[Findings]By analyzing and interpreting the charts,the patent information in the field of lithium-ion bat-tery diaphragm in Tianjin is statistically analyzed about the dimensions of application trend,geographi-cal distribution,major applicants,and technology distribution.[Conclusions]Currently,the local lithium-ion battery separator industry in Tianjin is generally weak.It is necessary to strengthen the culti-vation and introduction of local advantageous enterprises in the field.Universities and research institutes in Tianjin also need to actively explore new research and development.
