FIELD: electricity.
SUBSTANCE: nano-dimension modified composite material corresponds to structural formula LipFexM1-x(PO4)t(AO4)1-t, where 0<p<2; 0<x<1; 0≤t≤1. In addition, material is doped with cations of the above semi-equivalent elements; at that, for iron positions: - M = Co, Ni, Mg, Ca, Zn, Al, Cu, Ti, Zr; and for phosphate positions: - A=S, Si, V, Mo. Medium linear sizes of crystals of the obtained nano-dimension material is 20-500 nm, thickness of carbon coating is 1-20 nm.
EFFECT: doping of material for iron and phosphorus positions allows increasing concentration of defects in lithium subarray, increasing ionic conductivity and specific power, capacitance and cycling duration of lithium-ion accumulator cells.
