COMPOSITE NANOMATERIAL FOR CHEMICAL SOURCES OF CURRENT AND METHOD OF OBTAINING THEREOF Russian patent published in 2014 - IPC H01M4/131 B82Y99/00 H01M4/1391 

FIELD: chemistry.

SUBSTANCE: invention relates to composite nanomaterial for chemical sources of current, consisting of powder of oxides of complex composition, mixed with electrically conductive carbon additive and binding agent. As powder of oxides of complex composition, used is nanocomposite material, in which oxides of complex composition are in core/shell form of nanoparticles, where carbon layer serves as shell, with said nanosized aggregates in composite material having interfacial nanodimensional carbon contacts and/or current pick-ups among each other. Invention also relates to method of obtaining claimed materials. Claimed material represents novel type of electrically conductive carbon-containing composite nanomaterials with wide range of specific electrical conductivity (0.1-1x10^-9 S/cm), suitable for application in lithium sources of current.

EFFECT: increased energy capacity characteristics and increased by life cycle of electrodes in the process of exploitation.
