High performance silicon nanoparticle anode in fluoroethylene carbonate-based electrolyte for Li-ion batteries.
نویسندگان
چکیده
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.
