Abstract

Polymers have played a vital role in developing next-generation energy storage devices. In the progress of lithium-ion batteries (LIBs), polymers have been widely used in the preparation of electrolytes and electrode binders, in both cases, due to their unique intrinsic properties, such as high thermal, mechanical, and electrochemical resistance. However, the main limitation of this type of material is its poor ionic conductivity at room temperature, which depends on its structural properties and preparation techniques. In this review, the fundamental properties and ion transport mechanisms characteristic of different types of ion-conducting polymers, such as solvent-free polymer electrolytes (SPE), gel polymer electrolytes (GPE), and composite polymer electrolytes (CPE), are reported. A current overview of lithium-ion-based battery systems, which can be improved using ion-conducting polymers, is also presented.   Resumen. Los polímeros han tomado un papel fundamental en el desarrollo de dispositivos de almacenamiento de energía de última generación.  En el perfeccionamiento de baterías de ion litio LIBs, los polímeros han sido utilizados ampliamente en preparación de electrolitos y aglomerantes para electrodos, en ambos casos debido a sus propiedades intrínsecas especiales como alta resistencia térmica, mecánica y electroquímica. Sin embargo, la principal limitante de este tipo de materiales es su pobre de conductividad iónica a temperatura ambiente, la cual depende de sus propiedades estructurales y técnicas de preparación. En esta revisión son presentadas las propiedades fundamentales y mecanismos de transporte iónico característicos de los diferentes tipos de polímeros conductores de iones, como los electrolitos poliméricos sin disolventes (SPE), electrolitos poliméricos en gel (GPE) y electrolitos poliméricos compuestos (CPE). También se presenta un panorama actual de los sistemas de baterías basadas en iones litio, que pueden ser mejoradas de mediante el uso de polímeros conductores de iones.
聚合物在不同锂离子电池导电电解质中的作用简评
聚合物在开发下一代储能设备方面发挥着至关重要的作用。在锂离子电池(LIB)的发展过程中,聚合物因其独特的固有特性,如高耐热性、高机械性能和高电化学性能,被广泛用于制备电解质和电极粘合剂。然而,这类材料的主要局限性在于室温下离子导电性较差,这取决于其结构特性和制备技术。本综述报告了无溶剂聚合物电解质(SPE)、凝胶聚合物电解质(GPE)和复合聚合物电解质(CPE)等不同类型离子传导聚合物的基本特性和离子传输机制。此外,还介绍了目前锂离子电池系统的概况,这些系统可利用离子传导聚合物加以改进。 摘要聚合物在下一代储能设备的开发中发挥着核心作用。 在锂离子电池 LIB 的改进过程中,聚合物因其特殊的固有特性(如高耐热性、高机械阻抗和高电化学阻抗)而被广泛应用于电解液制备和电极粘合剂中。然而,这些材料的主要局限性在于室温下离子导电性较差,这取决于它们的结构特性和制备技术。本综述介绍了无溶剂聚合物电解质(SPE)、凝胶聚合物电解质(GPE)和复合聚合物电解质(CPE)等不同类型离子导电聚合物的基本特性和离子传输机制。此外,还介绍了锂离子电池系统的最新概况,使用离子传导聚合物可以改善这些系统的性能。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
