INVESTIGATION ON THE PERFORMANCE OF LI-DOPED OF REFINED PITCH COKE

The petroleum pitch was undergone refined and infused treatment.The heat treatment temperature(HTT) of refined pitch coke was examined and results indicated that the reversible capacity of the coke(HTT=1100℃) was the largest and the coulombic efficiency of the coke(HTT=900℃)was the highest.Yields of pitch coke,refined pitch coke and infusible refined pitch coke and the initial charge/discharge performance of the last one were examined.
