The materials batteries have host compositional range. used for the negative and positive electrodes of rechargeable “lithium-ion” structures that can accommodate and release lithium over a wide In these batteries, carbon and intermetallic compounds have been widely exploited as the negative electrodes, and transition metal oxides as the positive electrodes. For a lithium-ion battery to perform...

[figure: see text] Monomer (R,R)-3-aza-3-(p-vinylbenzyl)-1,5-diphenyl-1,5-dihydroxypentane (2) when polymerized with styrene and divinylbenzene affords polymers, onto which lithium and aluminum are incorporated via reaction with lithium aluminum hydride. The resulting insoluble polymers containing chiral lithium and aluminum active centers are quite effective for asymmetric Michael addition of ...

Lithium and nickel present low toxicity, but are able to cause alterations in different tissues. The toxic effects of lithium and nickel at different cellular levels were assessed using two inorganic chemical species: lithium chloride and nickel(II) chloride. Mouse neuroblastoma cell cultures (Neuro-2a) were exposed to both compounds for 24 h. The cytotoxic effects evaluated were cell prolifera...

The recent discovery of heavy-Fermion properties in Lithium Vanadate and the enormous difference in its properties from the properties of Lithium Ti-tanate as well as of the manganite compounds raise some puzzling questions about strongly correlated Fermions. These are disscussed as well as a solution to the puzzles provided.

Lithium cyclopentadienides are important reagents for the synthesis of organometallic compounds. In addition they feature an interesting manifold of structural variations in solution and in the crystal [1]. Variable temperature NMR spectroscopy has revealed markedly temperature dependent equilibria between monomeric lithium cyclopentadienides and their respective lithiocene salts [2]. A typical...

The demand for next generation of lithium based batteries with higher capacity and rate as well as increased cycle and calendar life requires new lithium storage and transfer mechanisms beyond what current lithium ion battery technique could provide. In lithium based battery, the lithium ions are stored in electrode materials either by physically intercalating (e.g. LiCoC2) or chemically alloyi...

Highly reactive glycosyl chlorides and bromides have been analysed by a routine mass spectrometric method using electrospray ionization and lithium salt adduct-forming agents in anhydrous acetonitrile solution, providing salient lithiated molecular ions [M+Li]⁺, [2M+Li]⁺ etc. The role of other adduct-forming salts has also been evaluated. The lithium salt method is useful for accurate mass dete...

Titanium-oxide-based materials are considered attractive and safe alternatives to carbonaceous anodes in Li-ion batteries. In particular, the ramsdellite form TiO2 (R) is known for its superior lithium-storage ability as the bulk material when compared with other titanates. In this work, we prepared V-doped lithium titanate ramsdellites with the formula Li0.5 Ti1-x Vx O2 (0≤x≤0.5) by a conventi...

The layered oxide compounds xLi2MnO3$(1 x)LiMO2 (M 1⁄4 Ni, Mn, Co) are of great interest as positive electrode materials for high energy density lithium-ion batteries. In-situ neutron diffraction was carried out to compare the structural changes between the classical layered compound Li[Ni1/3Mn1/3Co1/3]O2 (x 1⁄4 0) and lithium-excess layered compound Li[Li0.2Ni0.18Mn0.53Co0.1]O2 (x 1⁄4 0.5) dur...
