| Abstract Scope |
Ionothermal pyrolysis of sugarcane bagasse using deep eutectic solvent was used to produce high yield (> 50 wt%) and N-rich (> 11 wt%) activated carbons (ACs). The obtained ACs with low surface area (< 10 m /g) and interlayer spacing comparable to graphite (3.35 Å), was used as anodes in both Li-ion battery (LIB) and Na-ion battery (NIB). The LIB and NIB anodes delivered capacities of 300 and 100 mAh/g, respectively after 10 cycles at 100 mA/g. Both batteries showed excellent cycling stabilities and rate capabilities. The 1st cycle Coulombic efficiency for the LIB and NIB anodes were 50% and 85%, respectively which increased to ~100% after 10 cycles in both batteries. These results show that dense carbons can be exploited as high-performance anodes and the ionothermal approach could offer sustainable synthesis route to make activated carbons which can be exploited as high-performance anode in LIBs and in other applications. |
