Abstract:

The patent profile and key technologies of the lithium industry were analyzed,the patent distribution of both domestic and overseas was compared,the development status,direction and problems of the lithium industry were summarized,so as to provide targeted suggestions for the development of China's lithium industry and promote China to achieve the“Double Carbon”goals.At present,global lithium industry had entered rapid development stage,with patents focusing on midstream for lithium battery materials and downstream for applications,forming a three-part in China,South Korea,and Japan.The lithium extraction technology from salt lake,ferrous lithium phosphate and ternary materials had been important research point.China′s lithium industry had good resources and R&D foundations,but there were still problems such as insufficient industry-university cooperation and patent distribution overseas,R&D focusing on technical performance indicators,and patent market value mining incomplete and so on.It was recommended that China’s lithium industry should strengthen government-industry-university-research cooperation and patent distribution overseas,comprehensively consider technical performance indicators and environmental protection,safety and other factors,and coordinate core technology research and research output industrialization to promote China's lithium industry to develop sustainably.

Key words: lithium industry, lithium extraction from salt lake, lithium battery, patent distribution
