PROCESS FOR PREPARATION OF CARBON MATERIAL FOR ELECTRODES OF LITHIUM-ION CURRENT SOURCES

摘要

A carbon material process for electrodes of lithium-ion current sources by heat treatment of intercalated graphite bulk in the reactor. The intercalated graphite bulk is subjected to repeated successive heat treatments while passing electric current directly through the intercalated graphite bulk with simultaneous withdrawal of gas products being produced in expansion in the process of the first heating, and final expansion is carried out in repeated heat treatments in the same reactor.
