Inhibition of transition-metal dissolution with an inert soluble product interface constructed by high-concentration electrolyte
Summary: The formation of a compact and stable cathode electrolyte interphase (CEI) film is a promising way to improve the high voltage resistance of lithium-ion batteries (LIBs). However, challenges arise due to the corrosion of hydrogen fluoride (HF) and the dissolution of transition metal ions (T...

| description | Summary: The formation of a compact and stable cathode electrolyte interphase (CEI) film is a promising way to improve the high voltage resistance of lithium-ion batteries (LIBs). However, challenges arise due to the corrosion of hydrogen fluoride (HF) and the dissolution of transition metal ions (TMs) in harsh conditions. To address this issue, researchers have constructed an anion-derived CEI film enriched with LiF and LiPO2F2 soluble product on the surface of LiNi0.5Mn1.5O4 (LNMO) cathode in highly concentrated electrolytes (HCEs). The strong binding of LiF and LiPO2F2 generated an inert LiPO2F2 soluble product interface, which inhibited HF corrosion and maintained the spinel structure of LNMO, contributing to a capacity retention of 92% after 200 cycles at 55°C in the resulting cell with a soluble LiPO2F2-containing CEI film. This new approach sheds light on improving the electrode/electrolyte interface for high-energy LIBs. |
