Abstract Lithium λ-MnO2 ion-sieves were prepared from spinel LiMn2O4 via treatment with nitric acid. The LiMn2O4 was synthesized by a solid state reaction between LiOH· H2O and MnO2. The effects of the calcination t...

TiO2 is a latent anode material for rechargeable lithium batteries. Our simulation models, basing lepidocrocite and 2-MnO2 type TiO2 were investigated by density functional theory (DFT). The key issues are focused o...
Manganese oxide was obtained by selective chemical leaching of lithium ion out from the spent LiMn2O4 electrode materials and in-situ phase transformation.The prepared manganese oxide was characterized by X-ray power ...
