FIELD: electric elements.
SUBSTANCE: invention relates to the field of accumulator technology, in particular, accumulators considered alternatives to known lithium accumulators. According to the invention, the method for producing a material of nanoparticles with ionic conductivity as a material for fluoride-ion batteries consists of: (i) a procedure of ball milling in an aerosol atmosphere and/or a vapour pressure atmosphere, (ii) excess synthesis, (iii) ball milling with surface-stabilising and conductivity-increasing solid and/or gel/liquid additives, or (iv) functionalisation of the material for producing functionalised nanoparticles (GSNP) containing a dispersion of graphene, carbon nanotubes, and/or an additional additive selected from carbon black, graphite, Si, and/or CFx. In the method, synthesised are fluorides (EmmFh), fluoride composites (Em1m1Em2m2…Fh1) wherein the first metal, metalloid, or nonmetal Em or Em1 and the second metal, metalloid, or nonmetal Em2 are differently selected from Cu, Pb, Fe, Sn, Zn, Bi, Cd, Co, Cr, Ni, Sb, C, Si, B, P, N, Ge, Ce, Se, Ca, Mg, Li, Na, K, Al, Sr, Ba, La, Sm, Eu, Cs, Gd, or Y.
EFFECT: eliminated problems of high resistance on surfaces, nanoparticle grain boundaries, or nanoparticle compartments, increased ionic conductivity, safety of the accumulator.
