Summary: Polymer electrolytes are being studied for their potential as solid-state ionic conductors in future lithium metal batteries. Poly(ethylene oxide)-based electrolytes, in particular, are favored for their high ion conductivity and compatibility with electrode interfaces. However, the trade-off between ion conductivity and mechanical strength enhancement is a challenge due to the coupling between lithium-ion transport and polymer chain motion. Low temperature ion conductivity and low cation transference numbers also hinder practical applications of these electrolytes in batteries.

Summary: LiNi0.8Co0.1Mn0.1O2 (NCM811) is a promising cathode material for high-energy-density Li-ion batteries (LIBs) due to its high capacity and low cost. However, it faces irreversible capacity fading at high cut-off voltages, mainly caused by hydrolysis reaction producing corrosive byproducts. By modifying the electrolyte with dual additives, a stable interfacial layer is formed to eliminate unfavorable reactions and suppress phase transitions. The dual additives also stabilize the electrolyte. With this strategy, the cycling stability of NCM811 at high voltages is significantly improved, providing a reference for high-voltage electrolyte design in LIBs.

Summary: Increasing the cut-off voltage of cathodes improves the energy density of Li||LiCoO2 batteries, but also leads to rapid battery degradation due to oxidation and deterioration. However, by using bis-(benzenesulfonyl)imide (BBSI) as an additive, a uniform and highly Li+ conductive cathode electrolyte interphase (CEI) is constructed, which stabilizes the batteries at 4.6 cut-off voltage and exhibits superior cycling and high-rate performance. The CEI, consisting of LiF and conductive Li+ moieties, improves Li+ migration, alleviates cathode degradation, and reduces other secondary degradation factors. Li||LiCoO2 batteries with 1% BBSI-containing electrolyte sustain 81.30% of initial capacity after 300 cycles at 0.5C, and 88.27% of initial capacity even after 500 cycles at 2C/3C.
