摘要:

磁场作为一种在储能系统中逐渐引起关注的调控策略,在提升锂离子电池电化学性能方面展现出重要潜力,具体包括设计电极结构、促进Li+扩散、降低极化效应和抑制锂枝晶的生长等。然而,对于磁场调控的机制路径、材料响应规律及其构建策略,相关研究尚处于探索阶段,未形成统一的理论体系。本文在系统梳理相关文献的基础上,围绕磁场辅助电池结构设计和无接触式性能调控两大方向,综述了其在晶体取向诱导、无序相晶体结构构建、垂直孔隙设计、电极-电解质界面调控机制等方面的研究进展。同时,重点分析了磁场促进自旋态重构、磁性定向、磁致伸缩效应和磁流体动力学效应等核心机制,并总结了用于分析磁场调控机制与响应行为的原位表征技术和多物理场建模方法。在归纳当前研究成果的基础上,进一步提出当前亟待解决的问题,并从材料响应机制、构建策略及多场耦合等角度提出了后续研究方向,旨在为磁场调控策略在高能锂离子电池系统中的深入发展提供思路参考。

Abstract:

Magnetic fields have emerged as a promising regulation strategy in energy storage systems, showing significant potential in enhancing the electrochemical performance of lithium-ion batteries (LIBs), including improved electrode structure, accelerated Li+ diffusion, reduced polarization, and suppressed lithium dendrite growth. However, a unified theoretical framework is still lacking due to the coexistence of diverse perspectives regarding magnetic mechanisms, magnetic material responses, and construction strategies. This review systematically summarizes recent advances from two key perspectives: magnetic-field-assisted structural design of battery components and contactless performance regulation strategies. Key developments are discussed in areas such as the induction of crystal orientation, formation of disordered phase crystal structures, design of vertical pore architectures, and regulation of the electrode-electrolyte interface. Furthermore, the core mechanisms of magnetic spin state reconstruction, magnetic orientation, magnetostriction, and magnetohydrodynamic effects are analyzed in depth. Recent advances in in-situ characterization techniques and multi-physics modeling approaches for analyzing magnetic regulation mechanisms and material responses are comprehensively reviewed. Based on this comprehensive overview, key scientific challenges are identified, and future research directions are proposed in terms of material-level response mechanisms, structural design strategies, and multiphysics coupling. These insights aim to support further exploration of magnetic field regulation strategies in high-energy LIBs systems.
