ANODE FOR LITHIUM-IONIC ACCUMULATOR AND METHOD OF ITS MANUFACTURING Russian patent published in 2014 - IPC H01M4/58

Abstract RU 2516372 C2

FIELD: chemistry.

SUBSTANCE: claimed invention describes different compositions and methods of their obtaining, which can be applied, for instance, for obtaining one or more anodes in accordance with claimed invention. Such anodes can be used, for instance, for obtaining one or more batteries, which can be used, for instance, in vehicles. In at least one version of anode realisation in accordance with claimed invention anode contains lithium-based compound with formula Li₄Ti_5-yM_yO₁₂, where M contains alloying metal, selected from group, consisting of molybdenum, tungsten, zirconium and hafnium, where 0<y≤1. In one of invention versions claimed anode can also contain chalcogen compound in form of sulphur, selenium or tellurium. Also described is method of obtaining anode based on lithium of said composition.

EFFECT: increase of thermal stability and protection against overcharging lithium battery due to application of anode composition with spinel type structure is technical result of claimed invention.
