Searching for the Best Electrolyte Composition for the C/Li 2 MnSiO 4 Based Battery System

Abstract

Stability of nine electrolyte solutions, prepared using the most commercially preferred salts and electrolytes, towards C/Li 2 MnSiO 4 nanocomposite cathode material was investigated in this research. The cathode material was synthesized via a one step sol-gel method and coated with a specific amount (30 wt.%) of conductive carbon layer after the primary carbon is removed and the material is reduced. Properties of the C/Li 2 MnSiO 4 nanocomposite were investigated by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Differential scanning calorimetry (DSC). Electrochemical behavior of electrolyte solution-cathode material compositions were examined by the charge/discharge tests (CDT) using electrochemical Li/Li + /(C/Li 2 MnSiO 4 ) cells. As a conclusion it is observed that LiPF 6 (EC:DMC) is the most suitable one among the examined electrolyte solutions for C/Li 2 MnSiO 4 systems.
