Abstract

The investigation of a wide range of energy materials under relevant operation conditions, allowing for real-time investigations of the (electro)chemical mechanisms governing the performance of related applications, is enabled by the new Operando Absorption and Emission Spectroscopy at EMIL (OÆSE) endstation in the Energy Materials In-situ Laboratory Berlin (EMIL) at the BESSY II synchrotron facility in Berlin, Germany. Currently primarily used for X-ray absorption spectroscopy (XAS) studies, the OÆSE endstation utilizes the undulator-based two-colour EMIL beamline (covering an energy range between 80 and 10000 eV) to enable soft, tender, and hard XAS. In this work, the setup, along with operando sample environments tailored to address specific questions, is described, emphasizing its modularity and adaptability, and detailing specific strategies to minimize undesired radiation-induced effects caused by the high brilliance of the EMIL beamline. The in situ growth of electrodeposited copper monitored by soft and hard XAS, at the Cu L3 edge (sXAS) and Cu K edge (hXAS), respectively, is used as a proof-of-concept experiment, showcasing the capabilities of the OÆSE endstation as a versatile tool for comprehensive in situ/operando studies of energy materials under relevant conditions.

BESSY II的OÆSE终端站:能源材料的operando x射线吸收光谱。
在德国柏林BESSY II同步加速器设施的柏林能源材料原位实验室(EMIL)的EMIL (OÆSE)终端站,新的Operando吸收和发射光谱装置可以在相关操作条件下对各种能源材料进行调查,从而实时调查控制相关应用性能的(电)化学机制。目前主要用于x射线吸收光谱(XAS)研究,OÆSE终端站利用基于波动器的双色EMIL光束线(覆盖80至10000 eV的能量范围)来实现软、软、硬XAS。在这项工作中,描述了该设置,以及为解决特定问题而量身定制的operando样品环境,强调了其模块化和适应性,并详细说明了减少EMIL光束线高亮度引起的不希望的辐射诱导效应的具体策略。通过软XAS和硬XAS分别在Cu L3边缘(sXAS)和Cu K边缘(hXAS)监测电沉积铜的原位生长,作为概念验证实验,展示了OÆSE终端站作为相关条件下能源材料原位/操作综合研究的多功能工具的能力。
