Electrochemical performance of carbide-derived carbon anodes for lithium-ion batteries

摘要: Abstract Carbide-derived carbons (CDCs), part of a large family carbon materials derived from carbide, are attractive for energy-related applications, such as batteries, supercapacitors, and fuel cells. Pore textures (micro-, meso-, macro-pores) structures (from amorphous to highly ordered graphite) CDCs can be controlled by changing the synthesis conditions carbide precursor. Adequate control structure, porosity in terms application an anode exploited maximize electrochemical capacity lithium ion batteries. In this study, use CDC anodes chlorine treatment B 4 C TiC 7 N 3 temperature range 600 °C 1200 °C has been explored. The discharge -CDC reaches highest value, 462 mA h g −1 , at 100 cycles, which is 25% higher than theoretical graphite (375 mA h g ). C-CDC meanwhile affords value 453 mA h g cycles. These results show that have excellent potential negative electrode Li battery exposed practical low 600–1200 °C. also provide 2–3 times better performance existing or hard systems.
