ABSTRACT

LixV2O5 (x = 0.1÷0.3) lithium-vanadium bronzes were synthesized by a solid-phase method and method of soft chemistry. Their electric properties were investigated. Electrochemical cycling of cells with LixV2O5 cathode and anode from the liquid and solid lithium was carried out. Lithium-vanadium bronze, obtained by method of soft chemistry were found to possess better the electrochemical characteristics than lithium-vanadium bronze, synthesized by solid-phase method.

Electroreduction of chromium (III) chloride and molybdenum (VI) oxide mixtures in a heat activated battery

O. V. Volkova, V. V. Zakharov

ABSTRACT

Discharge characteristics of a heat activated battery with CrCl3 –MoO3 mixtures as a cathode material is investigated. Composition and morphology of reduction products of the cathode materials have been determined. A mechanism of the reduction to metallic chromium and molibdenum has been proposed, which includes an intermediate step of melt formation of a Li3CrCl6 complex compound and lithium molybdates with LiCl.
