摘要

For the first time, a novel finding, that the combustion products of dimethyl silicone oil can be used asthe anode materials for lithium ion batteries (LIBs), was reported in this work. Namely, a properamount of dimethyl silicone oil was burned at 800℃ in a muffle furnace for 2 h, leading to theformation of two kinds of products, namely, white particles (sample a) and black particles (sample b).And then, sample a was thoroughly mixed with sample b at the mass ratio of 1:1 generating a new kindof material (sample c). All prepared samples were respectively characterized by XRD, SEM and XPS.No typical diffraction peaks were found in all resultant XRD patterns which strongly indicated that allprepared samples were amorphous in nature. SEM images revealed that many large spherical particleswere prepared in sample a, and sample b contained many irregular large blocky particles. The resultsof galvanostatic charge and discharge experiments indicated that the initial discharge capacities ofsample a, b and c at 100 mA g-1 were 43, 41 and 68 mAh g-1, respectively. Interestingly, after 50cycles, the discharge capacities at 100 mA g-1 of sample a, b and c were 30, 48 and 44 mAh g-1,respectively. Summarily, a novel way, i.e., burning the Si-contained organic substances to prepareanode materials for LIBs, was developed in this work, which was very meaningful to the developmentof LIBs anode materials.
