Abstract

The electrochemical performances of LiNi0.5Mn1.5O4 (LNMO) have been improved by adding 0.5 wt.% (Trimethoxysilyl)naphthalene (TMSN) in carbonate electrolyte. The linear sweep voltammetry (LSV) test shows TMSN could preferentially undergo oxidative decomposition during charging process, which further inhibits the electrolyte decomposition. LNMO/Li half-cell presents better rate capabilities and an increased capacity retention of 89.3% after 200 cycles at 1 C by adding 0.5wt. % TMSN, indicating that TMSN can significantly reduce the HF content in the electrolytes and form a stable electrolyte/electrode interfacial on LNMO's surface.
