Abstract

The in situ XAFS technique has been applied for the first time to reveal variations in the local structures of Mn atoms during the charge-discharge process of LiMn{sub 2}O{sub 4}, Li(Mn{sub 1.93}Li{sub 0.07})O{sub 4}, and Li(Mn{sub 1.85}Li{sub 0.7})O{sub 4} cathode materials of lithium-ion secondary batteries. It has been demonstrated that the valence state of manganese is in a linear correlation with the peak energy of the Mn K-edge XANES spectrum. EXAFS analysis disclosed the {sup 3}+ Mn{sup 4}+ coexistence of Mn and in LiMn{sub 2}O{sub 4}, with two distinct Mn-O bond distances of 1.98 and 1.88{angstrom} for the Mn{sup 3+}.

LiMn{sub 2-x}Cu{sub x}O{sub 4} spinels (0.1 {le} x {le} 0.5) - a new class of 5 V cathode materials for Li batteries : I. electrochemical, structural and spectroscopic studies.

Conference Ein-Eli, Y

A series of electroactive spinel compounds, LiMn{sub 2{minus}x}Cu{sub x}O{sub 4} (0.1 {le} x {le} 0.5) has been studied by crystallographic, spectroscopic and electrochemical methods and by electron-microscopy. These LiMn{sub 2{minus}x}Cu{sub x}O{sub 4} spinels are nearly identical in structure to cubic LiMn{sub 2}O{sub 4} and successfully undergo reversible Li intercalation. The electrochemical data show a remarkable reversible electrochemical process at 4.9 V which is attributed to the oxidation of Cu{sup 2+} to Cu{sub 3+}. The inclusion of Cu in the spinel structure enhances the electrochemical stability of these materials upon cycling. The initial capacity of LiMn{sub 2{minus}x}Cu{sub x}O{sub 4} spinels decreasesmore »« less

Nanocrystalline Li{sub x}Mn{sub 2{minus}y}O{sub 4} cathodes for solid-state thin-film rechargeable lithium batteries

Journal Article Dudney, N; Bates, J; Zuhr, R; ... - Journal of the Electrochemical Society

Thin-film cathodes of lithium manganese oxide, 0.3--3 {micro}m thick, were deposited by rf magnetron sputtering of a LiMn{sub 2}O{sub 4} ceramic target onto unheated substrates. The resulting films were dense, {approximately}4.2 g/cm{sup 3}, with a {approximately}50 {angstrom} nanocrystalline spinel structure. The film composition was typically Li{sub x}Mn{sub 2{minus}y}O{sub 4} with y {approximately} 0.3 and 1.2 < x < 2.2. When cycled in a thin-film rechargeable lithium battery, specific cathode capacities of 145 {+-} 23 and {approximately}270 mAh/g were realized for discharge from 4.5 V to either 2.5 or 1.5 V, respectively. The discharge and charge current densities were limited bymore »« less

Cr{sup 3+} modified LiMn{sub 2}O{sub 4} spinel intercalation cathodes through oxalic acid assisted sol-gel method for lithium rechargeable batteries

Journal Article Thirunakaran, R; Kim, Ki-Tae; Kang, Yong-Mook; ... - Materials Research Bulletin

To improve the cycle performance of eco-friendly and cost-effective spinel LiMn{sub 2}O{sub 4} as the cathode of 4 V class Li secondary batteries, the spinel phase LiCr{sub x}Mn{sub 2-x}O{sub 4} (x = 0.01-0.20) was synthesized by soft chemistry method using oxalic acid as chelating agent. The present technique results in better homogeneity, good surface morphology, shorter heat treatment time, sub-micron sized particles, good agglomeration and better crystallinity. Electrochemical studies were monitored in the potential range of 3-4.5 V. The present paper reveals that chromium substituted manganese spinel improves the structural stability of the parent material.

Stabilization of LiMn{sub 2}O{sub 4} spinel electrodes for lithium batteries.

Conference Kim, J; Johnson, C; Vaughey, J; ...

Despite the structural and thermal stability of LiMn{sub 2}O{sub 4} compared with LiCoO{sub 2} and LiNiO{sub 2} electrodes, the solubility of LiMn{sub 2}O{sub 4} spinel electrodes has precluded their widespread use in commercial lithium-ion cells. The solubility problem has been attributed to attack of the spinel particles by acidic species in the electrolyte, such as HF, which induces a isproportionation reaction at the particle surface: 2 Mn{sup 3+}(solid) {yields} Mn{sup 4+}(solid) + Mn{sup 2+}(solution). Many efforts have been made to minimize the solubility of the spinel electrode, for example, by substituting mono-, di- or trivalent cations for some of themore »« less
