摘　　要：锂被称为21世纪改变世界的“绿色能源金属”和“白色石油”,其战略意义显著。在过去的一个世纪里,锂的开采和加工方式存在高能耗、高化学品消耗、低资源利用率、高环境污染等问题。现在,美国普林斯顿大学开发出一种基于3D多孔纤维绳的卤水提锂新技术,可以大幅减少锂生产所需的土地和时间。文章对该技术的原理、优点进行了评论,同时与我国科研人员独创的“太阳池-立体结晶法”提锂工艺进行对比。该新技术不仅可以提高现有锂盐生产线的产量,还可以扩大锂资源的可开采和利用范围,能应用于以前因锂浓度太低而不具有经济价值的锂资源,例如废弃的油气井和地热盐水,以及拥有广阔锂资源的海洋,同时该技术还可以节省大量的水,比传统的盐田蒸发更环保。相信随着该技术理论和工艺的不断发展,将会颠覆提锂技术,同时推动现有锂行业的蓬勃发展,促进全球新能源产业快速发展。Lithium,commonly referred to as the“green energy metal”and“white oil,”is anticipated to revolutionize the world in the 21st century due to its substantial strategic implications.However,the extraction and processing of lithium have encountered numerous challenges throughout the previous century,including excessive energy and chemical consumption,limited resource utilization,and detrimental environmental impact.The research from Princeton University in the United States has recently pioneered an innovative lithium extraction technology employing a system of intricately woven porous fibers,which exhibits the potential to considerably diminish the land and temporal requirements associated with lithium production.This article presents an introduction to a novel technology utilizing 3D porous fiber rope for the extraction of lithium resources from brine.Additionally,the progressive enhancements were introduced made in the“Solar Pond-Stereoscopic Crystallization Method”at Zabuye Salt Lake by Chinese researchers.Given the escalating need for clean energy technology,this innovative approach holds significant potential in fostering a more environmentally friendly and sustainable future.This technology has the potential to enhance the production capacity of current lithium facilities,while also enabling the exploration of previously disregarded lithium sources,including abandoned oil and gas wells and geothermal brine.Particularly,it holds promise for oceans abundant in lithium resources.Furthermore,this technology offers significant water conservation benefits and exhibits greater environmental compatibility compared to conventional evaporation techniques.It is anticipated that through the ongoing advancements and refinement of new technological theories and processes,it will overturn the lithium extraction technology,while promoting the vigorous development of the existing lithium industry and promoting the rapid development of the global new energy industry.
