Suppressing initial capacity fade in Li-rich LiFeO with anionic redox by partial Co substitution
Anu Maria Augustine, Vishnu Sudarsanan, P. Ravindran
The increasing relevance of energy storage technologies demands high-capacity cathode materials for Li-ion batteries. Recently, Li-rich defect anti-fluorite LiFeO has emerg…
First principle studies on electronic and thermoelectric properties of FeTiSn based multinary Heusler alloys
Mukesh K. Choudhary, H. Fjellvåg, P. Ravindran
The alloys with 8/18/24 valence electron count (VEC) are promising candidates for efficient energy conversion and refrigeration applications at low as well as high temperatures. Th…
First principle design of new thermoelectrics from TiNiSn based pentanary alloys based on 18 valence electron rule
Mukesh K. Choudhary, P. Ravindran
In this study, we have reported electronic structure, lattice dynamics, and thermoelectric (TE) transport properties of a new family of pentanary substituted TiNiSn systems using t…
Investigation of electronic structure and electrochemical properties of Na2MnSiO4 as a cathode material for Na-ion batteries
Vishnu Sudarsanan, Anu Maria Augustine, P Ravindran
The polyanionic compound Na2MnSiO4 is regarded as one of the promising cathode materials for Na-ion batteries due to good specific capacity with its attractive prospect of utilizat…
Structural phase stability, electronic structure, magnetic properties and chemical bonding analysis of transition metal ammine borohydrides with amphoteric hydrogen for hydrogen storage
S Kiruthika, P Ravindran
Usually the ions of a particular element in solids are in positive or negative oxidation states, depending upon the chemical environment. It is highly unusual for an atom having bo…
Electron doping of the layered nickelate LaNiO by aluminum substitution: A combined experimental and DFT study
Manimuthu Periyasamy, Lokanath Patra, Øystein S. Fjellvåg +5
The physical properties of LaNiO with a 2D-like Ruddlesden-Popper-type crystal structure are extraordinarily dependent on temperature and chemical substitution. By i…
