Preparation and electrochemical characteristics of waste-tire char-based CFX for lithium-ion primary batteries

In this study, we investigate the opportunity of using waste tire char as a cathode material for lithium-ion primary batteries (LPBs). The char obtained by carbonizing waste tires was washed with acid and thermally fluorinated to produce CF X . The structural and chemical properties of the char and CF X were analyzed to evaluate the effect of thermal fluorination. The carbon structure of the char was increasingly converted to CF X structure as the fluorination temperature increased. In addition, the manufactured CF X -based LPBs were evaluated through electrochemical analysis. The discharge capacity of the CF X reached a maximum of 800 mAh/g, which is comparable to that of CF X -based LPBs manufactured from other carbon sources. On the basis of these results, the use of waste tire char-based CF X as a cathode material for LPBs is presented as a new opportunity in the field of waste tire recycling.
