Abstract
Gaining fundamental insights into the interfacial electrochemistry in advanced battery systems, specifically the solid electrolyte interphases (SEIs), is key for the development of their practical applications. Electrochemical atomic force microscopy (EC-AFM) and its derivatives have been regarded as powerful and promising tools to reveal the SEI formation and evolution at the micro-/nanoscale and in real time. In this review, we present EC-AFM observations of the dynamic processes and structures of SEI in both liquid and solid electrolyte batteries. We show functional modes that enable the high-resolution monitoring of local modulus, viscosity, and ionic migration. Related techniques, mainly scanning electrochemical microscopy, are also introduced for probing the electrochemical reactivity and its distribution.
从根本上了解先进电池系统的界面电化学，特别是固体电解质相间层（SEIs），是开发其实际应用的关键。电化学原子力显微镜（EC-AFM）及其衍生物被认为是在微米/纳米尺度上实时揭示 SEI 形成和演变的强大而有前途的工具。在本综述中，我们介绍了 EC-AFM 对液态和固态电解质电池中 SEI 动态过程和结构的观察。我们展示了能够高分辨率监测局部模量、粘度和离子迁移的功能模式。我们还介绍了相关技术，主要是扫描电化学显微镜，用于探测电化学反应性及其分布。
期刊介绍：
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
