Description

technical field [0001] The invention relates to the technical field of hard carbon material production, in particular to a hard carbon material production pretreatment device. Background technique [0002] Hard carbon refers to carbon that is difficult to be graphitized. It is the thermal decomposition of polymers. Hard carbon can be obtained by thermally decomposing cross-linked resins with special structures at about 1000 ° C. This type of carbon is difficult to obtain at high temperatures above 2500 ° C. Graphitization, common hard carbons include resin carbon, organic polymer pyrolytic carbon, and carbon black, etc. Hard carbon also has problems such as large changes in discharge voltage with capacity, and the first charge and discharge efficiency is lower than that of graphitized carbon. For hard carbon materials The research on the modification of hard carbon is one of the important ways to improve the hard carbon as the negative electrode lithium ion battery material....
