Reduced Interfacial Resistance in Li Cells with Additives

摘要

Reduced interfacial resistance was achieved in Li cells with new additives.Polyvinylidene diflouride (PVDF) based gelled electrolyte thin films containing a mixture of ethylene carbonate and diethyl carbonate with and without additives were prepared. A doctor-blade technique was used to prepare these films. The additives studied include nitrile sucrose, and nitrile cellulose and their lithium salts. For electrochemical measurements, the PVDF gelled electrolyte films were sandwiched between two oxide free lithium foils.
