FIELD: electrochemical power engineering.
SUBSTANCE: invention relates to electrochemical power engineering, in particular to production of anode material based on titanium dioxide metastable β-phase doped with vanadium for use in lithium- and sodium-ion batteries, used for power supply of large-sized electric power plants of hybrid and electric vehicles, systems of uninterrupted power supply, robotics and self-contained marine vehicles, etc., as well as to method of its manufacturing. According to the invention, nanostructured vanadium doped titanium dioxide in a crystalline modification of bronze relates to solid solutions of formula Ti1-xVxO2(B), where x=0.02–0.06.
EFFECT: high specific parameters, improved speed characteristics, high stability of the structure during cycling, including under conditions of forced charge of active anode material.
