摘要：
石墨中的阴离子插层过程及其可逆性在下一代储能设备中起着至关重要的作用。本文利用从小角度到宽角度的operando X射线散射，研究了铝石墨双离子电池的反应机制。通过直接测量重复的插层距离以及阴极石墨的微孔率，首次观察到了石墨插层化合物（GIC）形成的阶行为、其相变及其可逆过程。研究证明了电化学插层过程的完全可逆性，以及插层引起的天然石墨的纳米和微米结构重组。这项工作为GIC形成过程中中间相变的热力学方面提供了新的见解。
英文摘要：
The process of anion intercalation in graphite and its reversibility plays a crucial role in the next generation energy-storage devices. Herein the reaction mechanism of the aluminum graphite dual ion cell by operando X-ray scattering from small angles to wide angles is investigated. The staging behavior of the graphite intercalation compound (GIC) formation, its phase transitions, and its reversible process are observed for the first time by directly measuring the repeated intercalation distance, along with the microporosity of the cathode graphite. The investigation demonstrates complete reversibility of the electrochemical intercalation process, alongside nano- and micro-structural reorganization of natural graphite induced by intercalation. This work represents a new insight into thermodynamic aspects taking place during intermediate phase transitions in the GIC formation.
