Polymerization behaviour of butyl bis(hydroxymethyl)phosphine oxide: Phosphorus containing polyethers for Li-ion conductivity

Polymers containing phosphorus groups and polyethers: from synthesis to application

UNLABELLED BACKGROUND Phosphorus-containing high performance polymers have aroused wide interest, mainly due to good mechanical properties and their excellent fire resistance. The flexibility of synthetic polyphosphoesters allows the development of polymers in order to obtain solid polymer electrolytes for rechargeable lithium batteries based on solid films with superior fire resistance. R...

Electrochemical properties of iron oxide nanoparticles as an anode for Li-ion batteries

The synthesis of iron oxide nano-particles by direct thermal decomposition was studied. Simultaneous thermal analysis and Fourier transform infrared spectroscopy results confirmed the formation of iron-urea complex, and disclosed iron oxide formation mechanism. Calcination of the iron-urea complex at 200°C and 250°C for 2 hrs. resulted in the formation of maghemite along with hematite as a seco...

Reversible 3-Li storage reactions of amorphous phosphorus as high capacity and cycling-stable anodes for Li-ion batteries.

An amorphous phosphorus/carbon nanocomposite demonstrates a reversible 3-Li storage capacity of 2355 mAh g(-1) with an excellent capacity retention of 90% over 100 cycles and a superior power capability with 62% of its capacity realizable at a very high rate of 8000 mA g(-1), possibly serving as a high capacity and high rate alternative anode for next-generation Li-ion batteries.

Todorokite-type manganese oxide nanowires as an intercalation cathode for Li-ion and Na-ion batteries

Surface analysis of anodic oxide films containing phosphorus on titanium.

PURPOSE To examine the effect of phosphoric acid solution on the anodic oxide film of titanium. MATERIALS AND METHODS Commercially pure grade 2 titanium specimens were prepared and anodized in phosphoric acid solution at a constant current density (70 A/m2). Specimens were evaluated by means of scanning electron microscopy, x-ray diffraction analysis, electron probe microanalysis, energy-disp...
