Electrolytic iron sulfides in prototype lithium batteries with gel electrolytes based on poly(vinyliden fluoride) and its derivatives

Electrolytic thin-film iron sulfide compounds were studied in prototype lithium batteries with gel electrolytes based on poly(vinyliden fluoride) and its derivatives by the method of galvanostatic cycling at room temperature. A discharge capacity of 200–280 mA h g^?1 in 80–180 cycles was obtained.

Titanium Dioxide Synthesized by Emulsion Method as a Material for Lithium Current Sources

Nanostructural titanium dioxide, TiO₂(E), synthesized by the emulsion method, was studied as cathode and anode of a lithium current source.     

Enhancing the efficiency of using electroplated iron and cobalt sulfides with a sublayer of NiC composite in a lithium battery

The efficiency of using in a lithium battery transition metal sulfides electroplated on a metal support strongly depends on the kind and relief of the support. To make the nickel support rougher for enhancing the adhesion of sulfides, it was electroplated with a nickel–carbon composite, NiC. The discharge capacity and the efficiency of cycling of iron and cobalt sulfides electroplated with a NiC sublayer were higher than in the case when the sulfides were electroplated on a smooth nickel support without composite coating.
