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 کاملLithium Sulfide/Metal Nanocomposite as a High-Capacity Cathode Prelithiation Material
DOI: 10.1002/aenm.201600154 due to their limited specific capacity.[18,19] Very recently, we have proposed that conversion reaction materials can be attractive high capacity prelithiation materials for cathodes and demonstrated using Li2O/metal and LiF/metal nanocomposites.[20,21] For example, a high “donor” lithium-ion specific capacity of 609 mAh g−1 has been achieved for a stable nanoscaled ...
متن کاملLithium-Fed Hollow Cathode Theory
A theory for the single-channel hollow cathode (SCHC) that includes the relevant physical processes and predicts the operating parameters is presented. A SCHC consists of a cylindrical channel approximately ten diameters in length through which a working gas (taken as lithium vapor here) flows and exits as a plasma. A high current (1-100 A) is conducted into the channel by the plasma and to 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 کاملNeutral hydrophilic cathode catalyst binders for microbial fuel cells†
Improving oxygen reduction in microbial fuel cell (MFC) cathodes requires a better understanding of the effects of the catalyst binder chemistry and properties on performance. A series of polystyrene-bpoly(ethylene oxide) (PS-b-PEO) polymers with systematically varying hydrophilicity were designed to determine the effect of the hydrophilic character of the binder on cathode performance. Increas...
