Abstract

Lithium metal battery (LMB) composed of lithium anode and ternary cathode has a high energy density exceeding 350 Wh kg-1. However, the high reactivity of the ternary cathode with electrolyte have seriously hindered its commercialization. In this paper, the electrolyte additive isocyanatopropyltriethoxysilane (ICPTES) was designed to protect NCM523 cathode by forming a silicon-oxygen polymer on cathode and removing the HF in carbonate-based electrolyte. Li||NCM cells with ICPTES exhibited the improved capacity and capacity retention.
