Abstract

Recent advancements in next-generation rechargeable batteries have focused on solid-state batteries (SSBs) due to their promising potential for improved energy density and safety. Among the various types of solid electrolytes, composite solid electrolytes (CSEs), composed of fillers and salts dispersed within a polymer matrix, have gained significant attention for their balanced properties of ionic conductivity and stability toward both electrodes, making them more suitable for practical SSB applications. In CSEs, the relationship between structure, properties, and performance is crucial. Unfortunately, conventional CSEs are still limited by randomly distributed fillers and agglomeration phenomena, which may impede ion transportation. Nanofiber fillers, characterized by their long-range structure, high surface area-to-volume ratios, and high aspect ratios, have the potential to significantly enhance CSE properties. Furthermore, they can shorten the ion-migration pathway and be aligned in a single direction. In this review, current technologies related to nanofiber-based CSEs are summarized. Typically, recent strategies for nanofiber structural design and synthesis, from principles to practical applications, are systematically reviewed. Subsequently, promising approaches to implementing nanofiber-based CSEs in SSBs with superior electrochemical performance and cyclability are discussed. Thus, this review provides a comprehensive overview of the state-of-the-art nanofiber-based CSEs for high-performance SSBs, which have the potential to safely accelerate the development of next-generation rechargeable batteries.

用于固态电池的纳米纤维基复合固体电解质：从基础到应用

下一代可充电电池的最新进展主要集中在固态电池（ssb）上，因为它们在提高能量密度和安全性方面具有很大的潜力。在各种类型的固体电解质中，由分散在聚合物基体中的填料和盐组成的复合固体电解质（CSEs）因其离子电导率和向两个电极的稳定性的平衡特性而受到广泛关注，使其更适合于SSB的实际应用。在cse中，结构、属性和性能之间的关系至关重要。遗憾的是，传统的cse仍然受到随机分布的填料和团聚现象的限制，这可能会阻碍离子的传输。纳米纤维填料具有长程结构、高表面积体积比和高长径比的特点，具有显著提高CSE性能的潜力。此外，它们可以缩短离子迁移途径并在单一方向上排列。本文综述了目前纳米纤维基cse的相关技术。本文系统地综述了纳米纤维结构设计和合成的最新策略，从原理到实际应用。随后，讨论了在SSBs中实现具有优异电化学性能和可循环性的纳米纤维基CSEs的有希望的方法。因此，本综述全面概述了用于高性能ssb的最先进的基于纳米纤维的CSEs，它有可能安全加速下一代可充电电池的发展。图形抽象
