Electrochemical Properties and First-Principle Analysis of Na x [M y Mn1-y ]O2 (M = Fe, Ni) Cathode
Sodium-ion batteries are the commercially and environmentally viable next-generation candidates for automobiles. Structural and electrochemical aspects are greater concerns towards the development of a stable cathode material. Selecting transition metals and their composition greatly influences charge order, superstructures, and different voltage plateaus. This, in turn, influences transport properties and cyclic performance. This article aims to study the electrochemical performance, diffusivity, and structural stability of Na x [M y Mn1−y ]O2 (M = Fe, Ni) as cathode.
Ab initio Simulations Of A Novel Sodium Superionic Conductor
In the current study, using first-principles simulations, we present a case for a novel composition: Na10GeP2S12 (NGPS), for application in room-temperature Na-S batteries.Solid electrolytes can enable safer and high-energy density batteries than liquid electrolytes .Sodium solid electrolytes can help in reducing the shuttling effect , which causes capacity loss in the newly emerging room-temperature Na-S batteries.
