FIELD: chemistry. n SUBSTANCE: invention relates to lithium-carrying iron phosphate in the form of micrometric mixed aggregates of nanometric particles, to an electrode and element, formed from them, to a method of their production, characterised by the stage of nano-milling, at which the micrometric mixed aggregates of the nanometric particles are formed by means of micro-forging. The invention also relates to electrodes and a Li-ionic electrochemical element. n EFFECT: application of claimed invention makes it possible to produce electrode materials making it possible to achieve practical energy density, which is higher than 140 W h/kg, in the lithium-ionic element which can be used to form thick electrodes at the industrial scale. n 26 cl, 7 dwg, 1 tbl, 6 ex |
