Favorable Interfacial Chemomechanics Enables Stable Cycling of High Li-Content Li-In/Sn Anodes in Sulfide Electrolyte Based Solid-State Batteries
Christian Hänsel, Baltej Singh, David Kiwic +2
Solid-state batteries (SSBs) can offer a paradigm shift in battery safety and energy density. Yet, the promise hinges on the ability to integrate high-performance electrodes with s…
Stoichiometric Tuning of Lattice Flexibility and Na Diffusion in NaAlSiO4: Quasielastic Neutron Scattering Experiment and Ab-initio Molecular Dynamics Simulations
Mayanak K. Gupta, Ranjan Mittal, Sajan Kumar +7
We have performed quasielastic neutron scattering (QENS) experiments up to 1243 K and ab-initio molecular dynamics (AIMD) simulations to investigate the Na diffusion in various pha…
Neutron-Irradiation Induced Magnetization and Persistent Defects at High Temperatures in Graphite
Ranjan Mittal, Mayanak K. Gupta, Sanjay K. Mishra +8
Structural as well as magnetization studies have been carried out on graphite samples irradiated by neutrons over 50 years in the CIRUS research reactor at Trombay. Neutron diffrac…
Phonons and Lithium diffusion in LiAlO
Mayanak K. Gupta, Ranjan Mittal, Baltej Singh +5
We report on investigations of phonons and lithium diffusion in LiAlO based on inelastic neutron scattering (INS) measurements of the phonon density of states (DOS) in γ-LiAlO$…
Anharmonic Phonons and Anomalous Thermal Expansion of Graphite
Ranjan Mittal, Mayanak K. Gupta, Baltej Singh +2
We have investigated the anisotropic thermal expansion of graphite using ab-initio calculation of lattice dynamics and anharmonicity of the phonons, which reveal that the negative…
Spin-Phonon Coupling and Thermodynamic Behaviour in YCrO3 and LaCrO3: Inelastic Neutron Scattering and Lattice Dynamics
Mayanak K. Gupta, Ranjan Mittal, Sanjay K. Mishra +4
We report detailed temperature-dependent inelastic neutron scattering and ab-initio lattice dynamics investigation of magnetic perovskites YCrO3 and LaCrO3. The magnetic neutron sc…
