Abstract：Lithium is the key metal to support the sustainable development of new energy industry. It is of great significance to realize the green recycling of characteristic lithium resources to ensure the safe supply of lithium resources in China. China's lithium resources are characterized by low overall grade of primary lithium resources,difficulty in efficient and clean utilization, low utilization efficiency of recycled lithium resources, and large demand for high-value recycling. Based on the characteristics of China's resources and industry, the progress of comprehensive utilization technology of characteristic lithium resources, such as salt lake lithium, ore lithium and recycled lithium, were systematically introduced. The current situation and development trend of lithium extraction technology of salt lake brine extraction and adsorption, lithium extraction technology of spodumene, lepidolite,clay-type lithium ore smelting, recycling technology of waste lithium ion battery and lithium extraction technology of other lithium-containing waste were emphatically analyzed. The current situation and development trend of lithium extraction technology were further proposed from the technical, industrial and policy levels. Suggestions on the construction of green recycling system of characteristic lithium resources in China were put forward in order to provide reference for the high-quality sustainable green development of lithium industry.
