Abstract

We use in operando Raman spectroscopy to investigate the structural evolution mechanism of transition metal cation and oxygen anion redox in Li-rich layered oxide cathodes. We directly capture the release of oxygen-driven electrolyte oxidation (especially the dimethyl carbonate component) at high-voltage operation (4.4 V).

在富锂层状氧化物阴极的高压循环中捕获氧驱动的电解质氧化

我们利用operando拉曼光谱研究了富锂层状氧化物阴极中过渡金属阳离子和氧阴离子氧化还原的结构演化机制。我们直接捕获了高压(4.4 V)下氧驱动电解质氧化(特别是碳酸二甲酯成分)的释放。

期刊介绍： ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
