Abstract

Clay minerals, including montmorillonite, vermiculite, palygorskite, sepiolite, halloysite, and kaolinite, demonstrate considerable potential for separator modification in lithium-ion batteries (LIBs) and lithium‑sulfur batteries (LiS) owing to their distinctive structural characteristics (layered/rod-like/tubular structures), high specific surface area, exceptional chemical stability, and cost-effectiveness. This comprehensive review systematically examines the structural features, classification systems, and modification approaches of clay minerals, while providing an overview of recent advancements in their application for LIB and LiS battery separators. Moreover, the performance enhancement mechanisms of clay mineral-modified separators are elucidated through detailed analysis of structural, compositional, and chemical property perspectives. The review also identifies current challenges associated with the implementation of clay minerals in battery separators and proposes prospective development directions and strategic solutions. By synthesizing these insights, this review aims to offer valuable guidance and stimulate innovative research toward the development of clay mineral-based separators for next-generation high-energy-density and high-safety battery systems.

黏土矿物基复合隔膜：特性、合成、在锂离子电池和锂离子电池中的应用、性能增强机理综述

粘土矿物，包括蒙脱土、蛭石、斜长石、海泡石、高岭土和高岭石，由于其独特的结构特征（层状/棒状/管状结构）、高比表面积、优异的化学稳定性和成本效益，在锂离子电池（LIBs）和锂硫电池（LiS）中表现出相当大的改性潜力。本文对粘土矿物的结构特征、分类体系和改性方法进行了系统的研究，并对其在锂离子电池和锂离子电池隔膜中的应用进行了综述。此外，通过对粘土矿物改性分选剂的结构、组成和化学性质的详细分析，阐明了粘土矿物改性分选剂的性能增强机理。该综述还指出了目前在电池分离器中应用粘土矿物所面临的挑战，并提出了未来的发展方向和战略解决方案。通过综合这些见解，本文旨在为下一代高能量密度和高安全性电池系统中粘土矿物基分离器的开发提供有价值的指导和激励创新研究。
