CARBON-CONTAINING MATERIAL FOR A LITHIUM-ION BATTERY AND A LITHIUM-ION BATTERY

摘要

The inventive carbon-containing material for a lithium-ion battery relates to electrical engineering and contains dispersed graphite and/or carbon nanostructures treated by a gas plasma in the inorganic gas or inorganic gas mixture atmosphere at an electric discharge frequency ranging from 13 to 40 MHz, the power thereof of 0.01-0.1 W/cm³ and the pressure of the inorganic gas or inorganic gas mixture of 0.2-1.13 Torr for 300-500 seconds. The inventive lithium-ion battery comprises positive and negative electrodes, electrolyte and a separator, wherein one electrode is made of said material. The inventive material does not require a complex process for the cleaning and production thereof and substantially increases the specific electric capacitance of the lithium-ion battery electrodes which are made thereof.
