About this Research Topic
Many in-situ characterization techniques have been implemented for Li-ion and Na-ion batteries and recently K-ion, Li-S and to some extent Li-O2 batteries. These range from:
• Neutron and synchrotron X-ray diffraction for long-rang ordered structural information,
• Solid-state NMR or X-ray absorption spectroscopy for local or shorter range structural information
• Raman spectroscopy for tracking charge/discharge products
• X-ray photoelectron spectroscopy for surface structure.
Over time, these techniques are becoming more and more widely used and in the future some of them will likely become a staple technique to elucidate battery materials structure-function relationships. All these techniques make up a great bundle of resources to go inside battery materials during operation, such as to probe the crystal structure evolution of electrodes while an electrochemical process is occurring inside a battery, even tracking lithium or sodium ion migration paths, to follow how the redox couple and its environment evolve, or even to be able to observe how electrode-electrolyte interface develops.
There is a distinct opportunity to obtain unparalleled insight into the structure and electrochemistry or property relationships inside batteries from which research and development can be stimulated and performance potentially exponentially enhanced. In this Research Topic we wish to create a means to illustrate the state of the art for in-situ and in-operando techniques and their results. We welcome submissions in the form of perspectives, mini-reviews, reviews and exemplary original research covering the spectrum of techniques.
