摘要

橄榄石型磷酸锰铁锂(LiMn

LMFP)作为下一代锂离子电池(LIBs)用正极材料，具有高能量密度、高安全性、低成本等优点。但LMFP本征电子电导率低、Li

扩散慢以及Mn

引发的Jahn-Teller效应等关键因素制约其大规模应用。本文系统论述了工业化共沉淀法在可控制备LMFP材料的研究进展，重点探讨了以磷酸盐和草酸盐为代表的前驱体在实现原子尺度上的均匀混合与组分精确控制方面的显著优势；进一步阐述了共沉淀法与改性策略(如浓度梯度设计、碳包覆与离子掺杂)相结合对提升LMFP正极材料电导率与结构稳定性方面的协同作用。最后，本文强调了共沉淀法为高性能LMFP材料的可控制备提供可行方案，未来研究需致力于反应机理研究、工艺参数优化与多种策略的系统性整合，从而推动其在大规模储能系统中的商业化应用。

Abstract

Olivine-type LiMn

LMFP) is regarded as a promising cathode material for advanced lithium-ion batteries owing to its low cost

high safety

and high energy density. However

its practical application is limited by intrinsically low ionic and electronic conductivity. In addition

a high Mn content induces severe Mn dissolution due to the Jahn-Teller effect

which significantly hinders the larg

e-scale deployment of LMFP. This review systematically summarizes recent progress in the controllable synthesis of LMFP cathodes using industrially relevant co-precipitation methods. Particular emphasis is placed on the advantages of phosphate and oxalate precursors in achieving atomic-scale homogeneous mixing and precise compositional control. Furthermore

co-precipitation strategies can be effectively combined with concentration gradient design

carbon coating

and ion doping to enhance electron and ion transport pathways and improve the overall electrical conductivity of LMFP. Finally

based on recent advances in co-precipitation techniques

this review outlines emerging research directions toward the commercial application of LMFP in large-scale energy storage systems.
