摘要

正极材料是决定锂离子电池性能上限的核心组分，但单一正极材料难以兼顾储能电池对能量密度、循环寿命、成本、安全性以及环境适应性等的多维度需求。层状/橄榄石混合正极材料通过复合高能量密度的层状氧化物与高安全性、长循环寿命的橄榄石磷酸盐材料，在保留各组分固有优势的基础上实现性能互补，成为突破这一技术瓶颈的有效策略。本文系统综述了层状/橄榄石混合正极材料的研究进展。首先简单介绍层状和橄榄石材料各自的晶体结构特征和电化学行为特点，重点探讨两类材料在颗粒尺寸匹配与电压平台兼容性方面的关键问题。其次，简单概述了层状/橄榄石混合正极材料的发展历程，并总结了混合正极的两种主要制备方式。进一步地，从界面稳定、结构强化与动力学优化三个层面揭示混合体系的协同作用机制，阐明该类材料在抑制界面副反应、缓解有害相变以及提升电化学反应动力学等方面的核心作用。上述三类机制相互关联、互为支撑，共同构筑协同增强效应，从而实现混合体系综合性能的协同提升。最后，结合当前储能技术的发展趋势，展望该类材料在大规模储能及固态电池等新型电池体系中的发展潜力，并梳理其深化研究方向和未来发展需求，以期为下一代高性能储能电池的发展提供材料支撑与理论参考。

Abstract

Cathode material is the core component that determines the upper limit of the performance of lithium-ion batteries. However

a single cathode material is difficult to meet the multi-dimensional requirements of energy storage batteries for energy density

cycle life

cost

safety

and environmental adaptability. The layered/olivine blended cathode materials

by combining the high energy density layered oxides with the high safety and long cycle life olivine phosphate materials

achieve performance complementarity while retaining the inherent advantages of each component

thus becoming an effective strategy to break through this technical bottleneck.This paper provides a systematic review of the research progress of layered/olivine blended cathode materials. Firstly

the crystal structure characteristics and respective electrochemical behavior feature of the layered oxides and olivine phosphates are briefly summarized. Based on this

the key issues of particle size matching and voltage platform compatibility when these two types of materials are combined are particularly analyzed. What's more

the development history and two typical preparation strategies of layered/olivine blended cathode materials are briefly reviewed. Furthermore

the synergistic mechanism of the blended system is revealed from three aspects: interface stability

structural reinforcement

and kinetic optimization. The core contributions of this strategy in inhibiting interface side reactions

alleviating harmful phase transitions

and enhancing the kinetics of electrochemical reactions are specifically explained. Specifically

the olivine component helps to regulate and stabilize the interfacial behavior of layered materials through physical isolation and interface modulation across contact interfaces

active regions

and film-forming layers. Relying on their own rigid polyanion framework structure

they realize multi-dimensional structural strengthening of the blended system from the atomic scale

grain scale and even electrode scale. At the same time

by forming a kinetic synergistic complementarity effect with the layered materials

they significantly optimize the electrochemical reaction kinetic performance of the electrode from the three dimensions of structural basis

thermodynamic equilibrium and dynamic process. It should be pointed out that the above three types of mechanisms do not exist in isolation but form an organic whole through mutual coupling and feedback regulation

jointly constructing a multi-scale synergistic enhancement effect

thereby significantly improving the comprehensive electrochemical performance of the blended system.Finally

based on the current development trend of energy storage technologies

the potential development of this type of material in large-scale energy storage and new battery systems such as solid-state batteries is discussed

and the in-depth research directions and future development requirements are summarized

with the aim of providing both material support and theoretical guidance for the development of the next-generation of high-performance energy storage batteries.
