Nov 1, 2021 · In this paper, the free-standing composite polymer electrolytes with high ionic conductivity were synthesized by solution casting method and changing mass fractions of Li 6 PS 5 Cl (LPSC) (1 wt%, 3 wt%) as active filler into the PEO-based polymer.

Jul 1, 2023 · Potentiodynamic methods like linear sweep voltammetry (LSV) have been used to determine the electrochemical stability window of PEO-based electrolytes in many previous publications [[9], [10], [11]], and these reported results are highly dependent on electrode properties and their surface state.

Sep 19, 2019 · Herein, a differentiated salt designed multilayered PEO-based solid polymer electrolyte (DSM-SPE) is exploited to achieve excellent electrochemical performance toward both the high-voltage LiCoO 2 cathode and the lithium metal anode.

Sep 9, 2023 · In this study, we focus on identifying the effect of long-term mechanical cycling (500 cycles) on the CPEs, without complex material changes induced by electrochemical cycling.

Oct 13, 2021 · Here, we develop a solvent-free preparation and matrix modification process for all-solid-state composite electrolytes (CSEs) based on the blended PVDF-HFP/PEO polymer matrix, and systematically study the effects of the solvent-free process on their properties.

Jul 15, 2023 · The PEO/10LLZTO@2LO solid composite polymer electrolyte (SCPE) showed the highest ionic conductivity of 3.2 × 10-4 S cm −1 at 40 °C as compared to pristine LLZTO-based SCPE. Moreover, the Li│(PEO/10LLZTO@2LO) │Li symmetric cell showed a stable and smooth long lifespan up to 1100 h at 40 °C.

Apr 29, 2022 · The electrochemical oxidation potential window of PEO was determined by linear sweep voltammetry (LSV) tests in Li/PEO/stainless steel (SS) coin-cells. The steel sheet worked as a working electrode (WE), and Li-metal worked …

Employing the solid polymer electrolyte (SPE) instead of traditional liquid electrolyte is an effective way to develop high safety and high-energy density solid-state lithium batteries....

A recent study on the thermal stability of PEO with LCO and polycrystalline NMC-811 demonstrated that PEO can suppress the oxygen release and thermal runaway of LCO owing to the formation of a passivation layer on the surface of the LCO particles.

Aug 18, 2022 · Poly (ethylene oxide) (PEO) and Li 6.75 La 3 Zr 1.75 Ta 0.25 O 12 (LLZTO)-based composite polymer electrolytes (CPEs) are considered one of the most promising solid electrolyte systems. However, agglomeration of LLZTO within PEO and lack of Li + channels result in poor electrochemical properties.
