NMR 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,...
متن کاملReaxFF molecular dynamics simulations on lithiated sulfur cathode materials.
Sulfur is a very promising cathode material for rechargeable energy storage devices. However, sulfur cathodes undergo a noticeable volume variation upon cycling, which induces mechanical stress. In spite of intensive investigation of the electrochemical behavior of the lithiated sulfur compounds, their mechanical properties are not very well understood. In order to fill this gap, we developed a...
متن کاملOxide diffusion in innovative SOFC cathode materials.
Oxide diffusion was studied in two innovative SOFC cathode materials, Ba(2)Co(9)O(14) and Ca(3)Co(4)O(9)+δ derivatives. Although oxygen diffusion was confirmed in the promising material Ba(2)Co(9)O(14), it was not possible to derive accurate transport parameters because of an oxidation process at the sample surface which has still to be clarified. In contrast, oxygen diffusion in the well-known...
متن کاملIn Situ X-ray Absorption Studies of Cathode Materials for Rechargeable Lithium-Ion Batteries
Rechargeable batteries with high energy and power density are in great demand as energy sources for various purposes; e.g., portable telecommunication, computer equipment, hybrid electric vehicles, etc. Lithiumion batteries are the most promising candidates to fulfill such needs due to their intrinsic high discharge voltage and relatively light weight. The current commercial lithium-ion battery...
