This study provides a new perspective on the design of high-performance cathode materials by demonstrating how the interplay between Li and transition metal migration in materials can be conducive to fast non-topotactic Li intercalation/de-intercalations. Using this concept, we show that high-rate performance can be achieved in Mn- and Ni-based cation-disordered rocksalt materials when some of the transition metal content can reversibly switch between octahedral and tetrahedral sites. The fast non-topotactic lithiation reaction is enabled by facile and reversible transition metal octahedral-to-tetrahedral migration, which improves rather than impedes Li transport. In contrast to this conventional view, here we demonstrate that the rate capability in a Li-rich cation-disordered rocksalt cathode can be significantly improved when the topotactic reaction is replaced by a non-topotactic reaction. A complex dataset analysis applicationĬrystalDiffract helps you analyze and run various simulations on sampled mineral data, in order to determine all its chemical, physical, optical and structural properties.High-rate cathode materials for Li-ion batteries require fast Li transport kinetics, which typically rely on topotactic Li intercalation/de-intercalation because it minimally disrupts Li transport pathways. In addition, you can easily monitor each simulation, as the application offers you extensive control over several aspects of your experiment, such as wavelength, peak shapes, zero correction and strain broadening.ĬrystalDiffract offers you the possibility to customize the display of imported or simulated data patterns, so that you can have a clearer view of your analysis.īesides, you can process your observed data, by applying offsets and relative intensity scaling or by removing any background noises, thus smoothing data. You can use the program to import multiple experimental datasets, then compare them with your simulated data, in order to find out certain particularities of each crystal or mineral. Furthermore, you can simulate certain phase transformations by on-the-fly editing any current properties. The application helps you analyze X-ray or neutron powder diffraction patterns, in order to accurately determine the chemical and physical properties of a sampled mineral. The program allows you to import various X-ray and neutron powder diffraction test results, then analyze them or perform simulations on the saved data samples. Crystaldiffract demo software#In order to analyze them, you need a powerful and reliable software application that can run simulations on your result data, in order to accurately determine the chemical and physical properties of a mineral or crystal.ĬrystalDiffract helps you do just that. The most common tests performed are X-ray crystallography and neutron powder diffraction, since they provide you with precise information about a mineral's qualities. Mineralogy is a scientific branch of geology that is specialized in the scientific study of crystal structure, chemical and physical properties of minerals. ![]()
