We used SiNSs as anodes and investigated the effect of fluoroethylene carbonate (FEC) additives on the SEI layer. Our XPS, EIS and TEM analysis of C-O and C=O bonds, interfacial resistance and thickness of SEI layer, respectively, shows that the FEC produces electrochemically and mechanically stable SEI layer. The SiNSs with FEC showed the capacity of over 1500 mA h g(-1) with 95% efficiency after 200 cycles. (C) 2017 Elsevier B.V. All rights reserved.
