Spinel LiNi0.5Mn1.5O4 Cathode for High-Energy Aqueous Lithium-Ion Batteries
DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...
متن کاملUltrathin surface modification by atomic layer deposition on high voltage cathode LiNi0.5Mn1.5O4 for lithium ion batteries
Atomic layer deposition (ALD) has been employed to modify the surface of high voltage cathode LiNi0.5Mn1.5O4 by coating ultrathin Al2O3 layer on the electrodes. The ultrathin layer of Al2O3 can suppress the undesirable reactions during cycling, while maintaining the electron and ion conductivity of the electrode. The ALD Al2O3 coated LiNi0.5Mn1.5O4 showed remarkable improvement over bare LiNi0....
متن کاملOptimization of Layered Cathode Materials for Lithium-Ion Batteries
This review presents a survey of the literature on recent progress in lithium-ion batteries, with the active sub-micron-sized particles of the positive electrode chosen in the family of lamellar compounds LiMO₂, where M stands for a mixture of Ni, Mn, Co elements, and in the family of yLi₂MnO₃•(1 - y)LiNi½Mn½O₂ layered-layered integrated materials. The structural, physical, and chemical propert...
متن کاملNMR studies of cathode materials for lithium-ion rechargeable batteries.
Lithium intercalation or insertion materials have been widely investigated in the search for new electrode materials for use in high-voltage rechargeable batteries.1-6 The first commercial Li-ion rechargeable battery contains the layered materials LiCoO2 (Figure 1) and graphite as the cathode (or positive electrode) and anode (or negative electrode), respectively.7 Although this battery is the ...
متن کاملLithium batteries and cathode materials.
In the previous paper Ralph Brodd and Martin Winter described the different kinds of batteries and fuel cells. In this paper I will describe lithium batteries in more detail, building an overall foundation for the papers that follow which describe specific components in some depth and usually with an emphasis on the materials behavior. The lithium battery industry is undergoing rapid expansion,...
