中文摘要:

在全球新能源产业快速发展的背景下,锂作为战略性关键矿产资源的需求持续攀升。盐湖卤水因其储量占比高及提锂成本低,成为锂资源开发的重点方向,但其高镁锂比、低锂浓度及复杂离子环境对提锂技术提出严峻挑战。相较于传统技术,锰基锂离子筛(LMO)吸附法凭借高选择性、高理论容量和环境友好性,成为最具工业化潜力的提锂技术路线。本文系统综述了尖晶石型LMO的结构调控与放大成型研究进展,着重总结和分析了LMO的结构调控策略(如掺杂、包覆、多级孔设计)和放大成型技术(造粒、成膜、载体负载),并探讨了其在高镁锂比盐湖提锂中的应用优势与挑战。

英文摘要:

Amid the rapid development of the global new energy industry, lithium, as a strategic critical mineral resource, has witnessed surging demand. Salt lake brine, characterized by its high reserve proportion (e.g., over 80% of China’s lithium resources) and low extraction costs, has become a key lithium source. However, challenges such as high Mg2?/Li? ratios (up to 1800:1), low lithium concentration (50-1500 mg/L), and complex ionic environments demand advanced extraction technologies. Compared to conventional methods, manganese-based lithium ion-sieves (LMO) have emerged as the most promising industrial-scale approach due to their high selectivity (Mg2?/Li? separation coefficient >100), theoretical capacity (>30 mg/g), and environmental compatibility. This review systematically summarizes recent advances in structural regulation and scale-up technologies of spinel-type LMO. This paper systematically reviews the research progress in the structure regulation and scale-up forming of spinel-type LMO, focusing on summarizing and analyzing the structure regulation strategies (such as doping, coating, hierarchical pore design) and scale-up forming techniques (granulation, film formation, carrier loading) of LMO, and discussing its application advantages and challenges in lithium extraction from high magnesium-to-lithium ratio salt lake brines.
