中文摘要:
      鉴于锂离子电池的大规模使用,锂产品在能源领域中扮演着至关重要的角色。然而,由于锂资源供应的不足,寻找高效的锂提取方法已成为当务之急,目前,固态锂资源在全球锂供应量中占主要部分,而受限于锂提取技术,资源量更大的液态锂资源的开发却非常有限,且液态锂资源生产成本更低,生产流程更简单,环境更友好,具有广阔的开发前景。电化学提锂方法则是一种潜力巨大的提取方法,该方法起源于摇椅电池,锂锰氧化物由于其优异性能是理想的电化学提锂电极材料。锰基材料电化学提锂方法具有高效、环保、可控、经济等优点,可以实现高效的锂提取和分离,同时减少环境污染和生产成本。未来随着锂需求的不断增加,锰基材料电化学提锂方法将会成为锂提取的重要技术。
英文摘要:
      The market of lithium-ion batteries is growing rapidly in recent years. Lithium products play a vital role in the sector of energy storage for their applications. However, due to the unsatisfactory demand for lithium resources, the search for efficient methods of lithium extraction addressed the need for the materials. Currently, solid lithium resources account for the major part of the global lithium supply, while the exploitation of lithium brine resources is limited due to inadequate extraction performance. On the other hand, lithium brine resources offer the advantages of low cost, natural abundance, and environmental friendliness. Electrochemical lithium extraction is a promising technique that is derived from the progress of rocking chair batteries. Lithium manganese oxide (LMO) is an ideal electrode material for electrochemical lithium extraction attributed to its excellent properties. Electrochemical lithium extractions based on LMO materials are highly efficient, environmentally friendly, controllable, and economical, thus enabling energy-saving extraction and separation while reducing environmental footprint and production costs. With the increasing demand for lithium products, electrochemical lithium extractions based on LMO materials will emerge as an important technique for supplying lithium.
