High performance silicon nanoparticle anode in fluoroethylene carbonate-based electrolyte for Li-ion batteriesElectronic supplementary information (ESI) available: Additional electrochemical tests, experimental details and additional figures are available. See DOI: 10.1039/c2cc31712e

Electrodes composed of silicon nanoparticles (SiNP) were prepared by slurry casting and then electrochemically tested in a fluoroethylene carbonate (FEC)-based electrolyte. The capacity retention after cycling was significantly improved compared to electrodes cycled in a traditional ethylene carbonate (EC)-based electrolyte. Slurry cast silicon nanoparticle-based electrodes matched with an electrolyte containing fluorinated ethylene carbonate show improved electrochemical performance for lithium storage.
