Abstract Solid polymer electrolytes (SPEs) make contact with highly reductive lithium (Li) metal anodes, forming the interphase that largely determines battery performance. In this work, trace iodine doping in a poly(ethylene oxide) (PEO) electrolyte to achieve stable on Li surface for long cycling, is proposed. The triiodide ion (I 3 − ) stemming from additives can coordinate COC bond of PEO enable increased ionic conductivity SPE. I‐doped contains I and IO , which spontaneously react dead 2 O at initial smooth surface, eventually leading significant improvements interfacial resistance dendrite suppression. When matching LiFePO 4 cathode, full cell exhibits higher capacity (150 mAh g −1 excellent cycling stability after 300 cycles (capacity retention 96.5%) 0.5 C 50 °C.

Non‐Flammable Ester Electrolyte with Boosted Stability Against Li for High‐Performance Li Metal Batteries

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(41)

Published: Aug. 19, 2022

Abstract In traditional non‐flammable electrolytes a trade‐off always exists between non‐flammability and battery performance. Previous research focused on reducing free solvents forming anion‐derived solid‐electrolyte interphase. However, the contribution of solvated anions in boosting stability electrolyte has been overlooked. Here, we resolve this via introducing into Li + solvation sheaths using with similar Gutmann donor number (DN) to that solvents. Taking trimethyl phosphate fire‐retardant (DN=23.0 kcal mol −1 ) NO 3 − (DN=22.2 as an example, is readily involved sheath reduces polarity solvent. This results boosted against Li. The developed low viscosity, high ionic conductivity cost. reversibility Li‐Cu cell was improved 99.49 % lifespan practical LMBs extended by >100 %.

Lithium fluoride (LiF), generated by the decomposition of in lithium metal batteries (LMBs), is considered an essential component for stabilizing metallic Li. However, substantial introduction fluorine raises potential environmental concerns. In this study, we designed a fluorine-free LMB integrating electrolyte and binder to construct B/O/N hybrid solid interphase (SEI) capable providing good stability fast Li+ transport ability. At test temperature 60 °C, LiF-free SEI can achieve highly reversible Li plating/stripping efficiency, with Coulombic efficiency 98.8% under conditions 3 mA cm–2 mAh cm–2. Furthermore, F-free battery exhibits rapid charging/discharging rate 100 C capacity exceeding 80 g–1 demonstrates stable cycling performance over 500 cycles at 50 C.
