Development of electrochemical performances of carbon black obtained by the surface organosilicon-modified method

Carbon black (CB) was simply modified by tert -butylchlorodimethylsilane (TBDMCl) to form the–C–OSiR and–C–OOSiR structures on the surface of CB. The formation of–C–OSiR and–C–OOSiR structures on CB was verified by FTIR and XRD measurements. The modified carbon black (MCB) has relative high electroc...

Summary:Carbon black (CB) was simply modified by tert -butylchlorodimethylsilane (TBDMCl) to form the–C–OSiR and–C–OOSiR structures on the surface of CB. The formation of–C–OSiR and–C–OOSiR structures on CB was verified by FTIR and XRD measurements. The modified carbon black (MCB) has relative high electrochemical performance, which was determined by electrochemical studies. The first charging capacity of MCB is at 343 mAh g –1 and the conductivity of MCB is at 148.1 Sm –1 which is similar to that of CB 155.2 Sm –1 . These results indicate that application of the obtained MCB will be promising for lithium anode materials. Meanwhile, these results can also suggest solving the overproduction problem of CB in China.
