Abstract:<\/h4>\n
The photopolymerization-induced microphase separation (photo-PIMS) process involving a reactive polymer block was implemented to fabricate nanostructured quasi-solid polymer electrolytes (QSPEs) for use in lithium metal batteries (LMBs). This innovative one-pot fabrication enhances interfacial properties in LMBs by enabling in situ<\/i> nanostructuring of QSPE directly onto the electrodes. This process also allows for customization of QSPE structural dimensions by tweaking the architecture and molar mass of poly[(oligo ethylene glycol) methyl ether methacrylate-co<\/i>-styrene] (P(OEGMA-co<\/i>-S)) macromolecular chain transfer agent. Bicontinuous nanoscale domains of soft P(OEGMA-co<\/i>-S)\/propylene carbonate\/lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) phase and hard poly[isobornyl acrylate-co<\/i>-(oligo ethylene glycol)diacrylate] phase furnished the QSPEs with respectively high ionic conductivity (0.34 mS cm-1<\/sup> at 30 \u00b0C) and interesting level of mechanical strength (106<\/sup>-107<\/sup> Pa at 30 \u00b0C). The as-prepared QSPE showed decent electrochemical properties and an electrochemical stability window of about 4.2 V vs Li+<\/sup>\/Li. This electrolyte enables the Li||SPE||Li symmetric cell to cycle over 350 h at 0.1 mA cm-2<\/sup> without evidence of dendrite formation. By means of galvanostatic cycling studies on a prototype lithium metal battery with LiNi0.8<\/sub>Mn0.1<\/sub>Co0.1<\/sub>O2<\/sub> or LiFePO4<\/sub> positive electrodes, we further demonstrate that the in situ<\/i> nanostructured QSPE exhibited better performances than the corresponding stacked battery.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1021\/acsami.4c15921 Authors: Kingsley Ikenna Aniagbaoso, Jan Bitenc, Virginie Pellerin, Maud Save, Antoine Bousquet, Laurent Rubatat Abstract: The photopolymerization-induced microphase separation (photo-PIMS) process involving a reactive polymer block was implemented to fabricate nanostructured quasi-solid polymer electrolytes (QSPEs) for use in lithium metal batteries (LMBs).
