Lithium-ion batteries (LIBs) with nonaqueous liquid electrolytes are prone to gas generation at elevated voltages and temperatures, degrading battery performance posing serious safety risks. Organosilicon (OS) additives an emerging candidate solution for gassing problems in LIBs, but a detailed understanding of their functional mechanisms remains elusive. In this work, we present combined computational experimental study elucidate the gas-reducing effects OS additives. Cell volume measurements chromatography–mass spectrometry reveal that can substantially reduce evolution particularly CO2 regardless source. Through density theory calculations, identify multiple plausible pathways evolution, including (1) nucleophile-induced ring-opening ethylene carbonate (EC) subsequent electro-oxidation (2) direct lithium (Li2CO3). Correspondingly, find function via two primary mechanisms: scavenging nucleophiles such as superoxide (O2•–), peroxide (O22–), ion (CO32–); oligomerization oxide dicarbonate ion. Moreover, discover possess strong coordination affinity, which helps further nucleophilic reaction energies hence increases nucleophile-scavenging efficiency. Finally, provide mechanistic interpretation enhanced gas-reduction observed fluorinated compounds, corroborated by surface analysis results from X-ray photoelectron spectroscopy. Our offers first molecular-level insights into how contribute reduced formation paving way improved LIBs.
