摘要
锂资源作为国内经济与军工体系建设的战略资源,在电化学、核工业、航空航天等领域起到至关重要的作用。随着国内对相关行业支持力度的增大,锂资源的消耗与开发利用日益增加。然而,中国锂消耗量对外依存度超过70%,在加快构建国内大循环为主体、国内国际双循环发展格局的背景下,高效、绿色地开发盐湖资源迫在眉睫。国内大多数盐湖卤水的高镁锂比、地理环境等因素增加了资源开发的壁垒。为此文章从各项技术原理、特点、性能等方面分析总结不同技术的特点,指出其所面临的潜在问题,最后对未来提锂技术的发展方向与研究重点进行了展望。
Lithium resources,as critical strategic assets,are essential for the development of domestic economic and military systems and play a pivotal role in fields such as electrochemistry,the nuclear industry,and aerospace.With growing domestic support for these industries,the consumption and utilization of lithium resources are on the rise.However,China’s lithium consumption is highly dependent on imports,with over 70%import dependency.In the context of promoting the domestic-centric economic cycle and the dual domestic-international development pattern,the efficient and environmentally sustainable development of salt lake resources has become an urgent priority.The high magnesium-lithium ratio and challenging geographical environment of most Chinese salt lake brines pose significant barriers to resource development.This study provides a comprehensive analysis of various lithium extraction technologies,examining their principles,characteristics and performance.It identifies potential challenges associated with these technologies and offers a prospective outlook on the future direction and research focus for lithium development.The aim is to enhance the efficient and green utilization of salt lake resources,thereby reducing reliance on foreign lithium sources and supporting the sustainable growth of lithium-related industries.
