Abstract

The performance of a lithium-ion cell depends on the form of the solid−electrolyte interphase (SEI) layers which is composed on the electrode surface. Here, we present a components of the electrolyte solutions for LIBs, namely, fluoroethylene carbonate (FEC) and vinyl carbonate (VC). We discuss the effect of 2, 5 and 10% FEC and VC-based electrolyte solutions in LiPF6 in EC:DEC to understand the SEI layer formed on Si anode.

FEC ve VC Katkılı Elektrolitin Lityum İyon Hücrelerde Si Anot Üzerine Etkisi

Abstract

Lityum iyon hücrelerin performansı, elektrot yüzeyinde oluşan Katı Elektrolit Arayüzey (KEY)’in yapısına bağlıdır. Bu çalışmada, elektrolit çözeltisinin bileşeni olarak FEC (floroetilen karbonat) ve VC (vinil karbonat)kullandık. %2, %5 ve %10 FEC ve VC katkılandırılmış EC:DEC içinde LiPF6 elektolitinin Si anot üzerinde oluşan KEY tabakasına etkileri tartışılmıştır.
