Abstract
The invention relates to the electrotechnical industry and can be used to produce a positive electrode (cathode) material based on layered transition metal oxides for lithium-ion storage batteries. An active cathode sulfur-containing composite material for lithium-ion batteries is in the form of a compound of the formula (1-a) LiNixMnyCozAvO2aLidSbOc, where LiNixMnyCozAvO2 is a component containing layered transition metal oxides, LidSbOc is an amorphous sulfur-containing component, and A is a doping agent selected from the group comprising Al, Mg, Zr, W, Ti, Cr, V, v<=0,1, x+y+z+v=1, 0.3<=x<=0.85; 0<=y<=0.3; 0<=z<=0.3; 0.0001<=a<=0.02, 0.001<=b<=2; 0<=c<=8; 0.001<=d<=2, wherein said composite material is produced from a sulfur-containing precursor compound of the formula: NixMnyCozOm(OH)2-2f(SbOc)f or NixMnyCoz(CO3)1-g(SbOc)g, where 0.3<=x<=0.85; 0<=y<=0.3; 0<=z<=0.3, 0<=m<=1, 0.001<=b<=2, 0<=c<=8, 0.0001<=f<=0.05, 0.0001<=g<=0.02. The technical result consists in improving the operating characteristics of the cathode material, specifically in increasing the charge/discharge cycles while maintaining a high specific capacitance as a result of introducing the amorphous sulfur-containing component LidSbOc into the composition of the cathode.
