CARBON-CONTAINING MATERIAL FOR LITHIUM-ION ACCUMULATOR AND LITHIUM-ION ACCUMULATOR Russian patent published in 2006 - IPC H01M10/40 H01M4/96 

FIELD: electric engineering, in particular, engineering of lithium accumulators.

SUBSTANCE: carbon-containing material for lithium-ion accumulator includes dispersed graphite and/or carbon nanostructures, processed by gas plasma in environment of non-organic gas or mixture of non-organic gases with frequency of electric discharge within range 13-40 MHz with power of electric discharge 0,01-0,1 Vt/cm³ and pressure of non-organic gas or mixture of non-organic gas in range 0,2-1,13 torr during 300-500 seconds. Lithium-ion accumulator includes positive electrode, negative electrode, electrolyte and separator, in which one of electrodes is made on basis of aforementioned carbon-containing material. Material does not require usage of complicated technology for its manufacture and cleaning, and during its utilization in electrodes of lithium-ion accumulator is provides significant increase of their specific electrical capacity.

EFFECT: increased electric specific capacity of lithium-ion accumulator with insignificant alteration of cost.
