Abstract

Though lithium-ion batteries (LIBs) are prevalent, the scarcity and uneven distribution of lithium resources have driven the search for complementary battery technologies. Potassium-ion batteries (PIBs) have emerged as a promising contender in this quest due to their low-cost, abundant resources, and potentially high voltage. The frequency of battery-related accidents in recent years has heightened concerns about battery safety. The electrolyte, as a critical component of batteries, plays a pivotal role in determining safety, as it is directly linked to the formation of the solid electrolyte interphase (SEI), which is crucial for battery stability and security. Initially, enhancing battery safety often came at the cost of performance. However, thanks to the relentless efforts and in-depth research, it is now possible to improve performance without compromising safety. This article provides an overview of organic electrolyte systems and introduces some state-of-the-art electrolyte formulations, aiming to offer guidance on enhancing the safety and stability of PIBs.

用于稳定和安全钾离子电池的有机电解质
虽然锂离子电池(lib)很普遍,但锂资源的稀缺性和不均匀分布促使人们寻找互补的电池技术。钾离子电池(PIBs)由于其低成本、丰富的资源和潜在的高电压而成为这一探索中有前途的竞争者。近年来与电池有关的事故频发,加剧了人们对电池安全的担忧。电解质作为电池的关键组成部分,对电池的安全性起着举足轻重的作用,因为它直接关系到固体电解质间相(SEI)的形成,而SEI对电池的稳定性和安全性至关重要。最初,提高电池安全性往往是以牺牲性能为代价的。然而,由于不懈的努力和深入的研究,现在有可能在不影响安全的情况下提高性能。本文概述了有机电解质体系,并介绍了一些最先进的电解质配方,旨在为提高pib的安全性和稳定性提供指导。
