STRONTIUM HEXAFERRITE AS CATHODE MATERIAL FOR LITHIUM BATTERY Russian patent published in 2014 - IPC H01M10/525 H01M6/00 C01G49/06 C01F11/02

Abstract RU 2510550 C1

FIELD: electricity.

SUBSTANCE: disclosed is a soluble precursor-derived composite oxide of the formula SrFe₁₂O₁₉ for use as an active substance for composite material of the positive electrode of a lithium battery, consisting of binding material, a current-conducting agent and active substance. A desired phase with different controlled particle sizes can be obtained by varying calcination temperature conditions. Selection of the particle size enables to optimise operational parameters of the battery. Maintaining the structure during discharge (lithium embedding) enabled to use up to 80-100% theoretical capacity of said material. Specific theoretical capacity is 303 mAh/g.

EFFECT: full utilisation of the material.

8 cl, 1 tbl, 6 dwg
