Layered Li-rich, Fe- and Mn-based cathode material, Li[Li0.2Fe0.1Ni0.15Mn0.55]O2, has been successfully synthesized by a coprecipitation method further modified with different coating amounts of AlPO4 (3, 5, 7 wt %). The effects on the structure, morphology electrochemical properties these materials are investigated systematically. XRD results show that pristine sample is obtained typical Li-rich layered structure trace amount Li3PO4 phase observed for coated samples. observations reveal all...
Nanostructured cathode materials with different dimensions (0D, 1D, 2D, and 3D), morphologies (hollow, core–shell, <italic>etc.</italic>), composites (mainly graphene-based composites) are highlighted, aiming to unravel the opportunities for development of future-generation lithium-ion batteries.
As the most promising cathodes of lithium-ion batteries, lithium-rich manganese-based layered oxides with high capacity suffer from poor cycle stability, rate capability, and fast voltage fading. Here we introduced AlF3 into surface cathode (Li[Li0.2Fe0.1Ni0.15Mn0.55]O2) as an artificial protective layer well inducer integrated layered-spinel structures to achieve both low cost capacity. The reduced irreversible loss, improved cycling superior high-rate capability were ascribed combination...
Hierarchical mesoporous/macroporous ultrathin Co<sub>3</sub>O<sub>4</sub> nanosheets were synthesized as free-standing catalysts for Li–O<sub>2</sub> batteries. Morphology of Li<sub>2</sub>O<sub>2</sub> could be changed by controlling the shape catalysts..
Photosensitizer is the key element in photodynamic therapy to generate singlet oxygen exert cytotoxic effects on cancerous or diseased tissues. Conventional organic photosensitizers generally have poor photostability. Nano-photosensitizers display high resistance photodegradation. However, toxicity of quantum dots and requirement UV light activation for ZnO TiO2 limit their practical applications. Here, we developed Au nanorod (Au NR)/ZnO core–shell nanostructures that integrate nanorods...
The improved properties of FePO<sub>4</sub>/Li<sub>3</sub>PO<sub>4</sub> coated Li[Li<sub>0.2</sub>Fe<sub>0.1</sub>Ni<sub>0.15</sub>Mn<sub>0.5</sub>]O<sub>2</sub> material are attributed to the suppression bulk from direct exposure with electrolyte by amorphous phase.
As promising cathode materials for lithium-ion batteries (LIBs), Fe-containing Li-rich compounds of Li1+x Fe0.1Ni0.15Mn0.55O y (0 ≤ x 0.3 and 1.9 2.05) have been successfully synthesized by calcining the spherical precursors with appropriate amounts lithium carbonate. The structures, morphologies, chemical states these are characterized to better understand corresponding electrochemical performances. With an increase content, evolves from a complex layered-spinel structure layered structure....
A novel Li-rich cathode Li[Li1/6Fe1/6Ni1/6Mn1/2]O2 (0.4Li2MnO3-0.6LiFe1/3Ni1/3Mn1/3O2) was synthesized by a sol-gel method, which uses citric acid (SC), tartaric (ST), or adipic (SA) as chelating agent. The structural, morphological, and electrochemical properties of the prepared samples were characterized various methods. X-ray diffraction showed that single-phase materials are formed mainly with typical α-NaFeO2 layered structure (R3̅m), SC sample has lowest Li/Ni cation disorder....
Lithium manganese silicate (Li2MnSiO4) is an attractive cathode material with a potential capacity above 300 mA h g–1 if both lithium ions can be extracted reversibly. Two drawbacks of low electronic conductivity and structural collapse could overcome by conductive surface coating porous structure. Porous morphology inner mesopores offers larger area shorter diffusion pathways also buffers the volume changes during insertion extraction. In this paper, mesoporous Li2MnSiO4 (M-Li2MnSiO4)...
