Solid polymer electrolytes (SPEs) represent a pivotal advance toward high-energy solid-state lithium metal batteries. However, inadequate interfacial contact remains significant bottleneck, impeding scalability and application. Inadequate Recent efforts have focused on transforming liquid/solid interfaces into solid/solid ones through in situ polymerization, which shows potential especially reducing interface impedance. Here, we designed high-voltage SSLMBs with dual-reinforced stable by combining modification an polymerization technology inspired targeted effects medicine. Theoretical calculations time-of-flight secondary ion mass spectrometry (TOF-SIMS) analysis demonstrate that tetramethylene sulfone (TMS) bis(2,2,2-trifluoromethyl) carbonate (TFEC) exhibit selective adsorption at the of LiNi

Quasi-solid polymer electrolytes with binary and ternary salt mixtures for high-voltage lithium metal batteries

Energy Materials, Journal Year: 2025, Volume and Issue: 5(4)

Published: Jan. 24, 2025

Quasi-solid polymer electrolytes (QSPEs) are considered a promising alternative to liquid for high-voltage lithium metal batteries. Herein, we present their properties and performance supported on polyolefin microporous separators. These QSPEs consist of poly(vinylidene-fluoride-co-hexafluoropropylene) matrix, ethylene carbonate as plasticizer, various salt mixtures, including bis(fluorosulfonyl)imide (LiFSI), bis(oxalate)borate (LiBOB), LiNO3 solid electrolyte interface-forming additive. They exhibit an ionic conductivity ca. 1 mS cm-1 at room temperature excellent resistance against dendrites, attributed the presence tough separator. The effect mixture composition plating/stripping electrooxidation stability was studied in detail, showing that LiNO3, while having clear positive performance, may also adversely affect oxidative electrolyte, accelerating degradation cathode/electrolyte interface. with binary LiFSI/LiBOB mixtures were tested LiNi0.8Mn0.1Co0.1O2||Li monolayer pouch cell cathode area capacity 2.5 mAh cm-2.
