LITHIUM BATTERIES, CONTAINING LITHIUM-CARRYING IRON PHOSPHATE AND CARBON Russian patent published in 2015 - IPC H01M4/58 H01M4/36 H01M4/62 H01M4/04 H01M10/525 H01M4/139 H01M4/136

Abstract RU 2551849 C2

FIELD: chemistry.

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.

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.
