软包锂电池铝塑膜专利技术分析
|
摘要
从专利申请趋势、技术输出国、主要申请人、技术功效分布和重点专利等不同角度分析了全球软包锂电池铝塑膜的专利技术信息,结果表明,2011年起,全球铝塑膜领域专利申请量快速增长。日本、中国和韩国是主要技术输出国,其中日本在铝塑膜领域占据绝对的技术优势,中国和韩国是铝塑膜领域的新兴力量。日本的凸版印刷、大日本油墨化学、昭和电工和大日本印刷株式会社是铝塑膜领域的主要申请人,中国申请人和这些申请人之间差距明显。使用特定的铝箔层、密封层、胶黏剂层或者在铝塑膜中设置附加层改进密合性能和耐腐蚀性,使用铝箔层、基材层、附加层改进成型性能,采用附加层改进铝塑膜的阻隔、防水性能和机械性能是技术研究热点。
The application trend, nationality distribution, major applicants, the technical means and technical efficacy distribution and the key patent of aluminum plastic film for lithium-ion battery were investigated from the perspective of patents. The result shows that patent applications increased rapidly since 2011. Japan, China, and South Korea are main technology exporter, and Japan has an absolute technological advantage while China and South Korea are emerging forces. Toppan Printing, DIC, Showa Denko, and DNP are major applicants, the gap between Chinese applicants and these applicants is huge. Using aluminum foil, sealant layer, adhesive layer or additional layer to improve peeling strength and corrosion resistance, using aluminum foil, base material layer, additional layer to improve molding performance, using additional layer to improve barrier and mechanical performance of the aluminum-plastic film are technical research hotspot.
