Simple Synthesis of Nanostructured Sn/Nitrogen-Doped Carbon Composite Using Nitrilotriacetic Acid as Lithium Ion Battery Anode

초록

A composite of 3.5 nm Sn nanoparticles dispersed in nitrogen-doped carbon was prepared from low cost precursors, using simple equipment, by the simple process of hydrolyzing at 300 degrees C SnCl4 mixed with nitrilotriacetic acid and then pyrolyzing the complexed SnO2 at 650 degrees C. The affordable anode made with the composite retained at 0.2 A g(-1) specific current a specific capacity of 660 mAh.g(-1) at the 200th cycle and a 630 mAh-g(-1) capacity at 400th cycle. At 1 A g(-1) specific current the capacity was as 435 mAh" g(-1).
