Abstract Aiming at discovering new positive electrode materials with superior electrochemical performance for application in lithium‐ion batteries, this work focuses on the design of fluorine‐free, manganese‐rich disordered rock salt (DRX) cathodes. Samples a starting composition Li 1.1 Mn 0.8 Ti 0.1 O 2 are successfully prepared by facile solid‐state synthesis and further optimized through experiments approach. Several key factors examined, including carbon type content as well lithium...
Improving interfacial stability between cathode active material (CAM) and solid electrolyte (SE) is vital for developing high-performance all-solid-state batteries (ASSBs), with compatibility issues among the cell components representing a major challenge. CAM surface coating chemically inert ion conductor promising approach to suppress side reactions occurring at interfaces. Another strategy mitigate mechanical degradation involves utilizing single-crystalline particle morphologies. Their...
Abstract Lithium neodymium titanate AB O 3 perovskites have been synthesized by a solid‐state synthesis route. All the samples sintered at 1250°C for 24 h followed slow cooling ∼ 10°C −1 undergo an ordering−induced polymorphic transformation where amount of ordering increases as A site cation vacancy content increases. Li 0.48 Nd 0.5 TiO 2.99 and then quenched to room temperature forms Pnma orthorhombic phase. This phase is also observed after 100 charging discharging cycles sample...
Mixed oxides of CoFeMn, ZnGaMn and CoFeGaMnZn have been pelletised, sintered at 1250°C for 24 hours, then quenched aged 375°C 150 hours to determine their phase compositions microstructure evolution. After sintering ageing, chessboard nanodomains CoFe2O4 CoMn2O4, ZnGa2O4 ZnMn2O4 spinel phases evolve in the CoFeMn oxides, respectively. In multicomponent oxide, similar are also observed after ageing. These all likely mixed chemistry, this often causes polymorphic transformations from crystal...
Vacuum induction melted equi-atomic NiMn alloy has been studied through x-ray diffraction (XRD) and transmission electron microscopy (TEM). The XRD pattern of the as-solidified may be matched with tI2 η′-NiMn phase cF4 Ni3Mn simultaneously. In TEM bright field image same alloy, alternating dark contrast chessboard-like appearance is observed. Electron patterns from match phase. are related to tetragonal additional superlattice reflection along [110] [112]. crystal structure new found...
