| Abstract | Silicon is a promising candidate anode material for lithium ion batteries due to its high theoretical specific capacityof 4,200 mAh g-1and low discharge potential. However, a high irreversible capacity loss due to a solid electrolyteinterphase formation on the surface of Si anodes during the 1st cycle limits its practical applications. Prelithiationis considered an attractive method that can be used to compensate for the active lithium losses during the 1st cycle.Surface oxidation to Li2O when the material comes into contact with moisture and oxygen during electrodefabrication is a main obstacle, leading to poor electrochemical stability. In this work the surface stability ofprelithiated Si-based nanoparticles was modified via a polymeric nano-coating method. The results demonstratethat coating with 1-fluorooctane is an effective strategy to mitigate irreversible capacity loss and provideelectrochemical stability for high performance next generation lithium ion batteries. |
