Lithium intercalation in heat-treated petroleum cokes

Petroleum needle cokes were processed by air-milling and heat treatment at three temperatures 1800, 2100 and 2350 °C, to produce a final average particle size of 10 p.m. The effects of air-milling (before and after heat treatment) on the physical and microstructural properties of the petroleum coke...

Zusammenfassung:	Petroleum needle cokes were processed by air-milling and heat treatment at three temperatures 1800, 2100 and 2350 °C, to produce a final average particle size of 10 p.m. The effects of air-milling (before and after heat treatment) on the physical and microstructural properties of the petroleum coke particles were examined. The results obtained for electrochemical lithium intercalation/de-intercalation in 0.5 M LiN(CF 3SO 2) 2/EC:DMC electrolyte using these petroleum cokes after the different processing conditions are reported.
