A relation with SPE oxidation was evaluated, for validity reasons on different active materials in potentiodynamic and galvanostatic experiments. The results indicate an exponential current increase and a potential plateau at 4.6 V vs. Li|Li+, respectively, demonstrating that the main oxidation onset of the SPE is above the used working potential of NMC622 being < 4.3 V vs. Li|Li+. Obviously, the SPE│NMC622 interface is unlikely to be the primary source of the observed sudden failure indicated by the “voltage noise”. Instead, our experiments indicate that the Li | SPE interface, and in particular, Li dendrite formation and penetration through the SPE membrane is the main source. This could be simply proven by increasing the SPE membrane thickness or by exchanging the Li metal negative electrode by graphite, which both revealed “voltage noise”-free operation. The effect of membrane thickness is also valid with LiFePO4 electrodes. In summary, it is the cell set-up (PEO thickness, negative electrode), which is crucial for the voltage-noise associated failure, and counterintuitively not a high potential of the positive electrode. 000874259 536__ $$0G:(DE-HGF)POF3-131$$a131 - Electrochemical Storage (POF3-131)$$cPOF3-131$$fPOF III$$x0 000874259 588__ $$aDataset connected to CrossRef 000874259 7001_ $$0P:(DE-Juel1)181055$$aStolz, Lukas$$b1 000874259 7001_ $$0P:(DE-Juel1)171863$$aNair, Jijeesh$$b2 000874259 7001_ $$0P:(DE-Juel1)171204$$aCekic-Laskovic, Isidora$$b3 000874259 7001_ $$0P:(DE-Juel1)166130$$aWinter, Martin$$b4 000874259 7001_ $$0P:(DE-Juel1)171865$$aKasnatscheew, Johannes$$b5$$eCorresponding author 000874259 773__ $$0PERI:(DE-600)2615211-3$$a10.1038/s41598-020-61373-9$$gVol. 10, no. 1, p. 4390$$n1$$p4390$$tScientific reports$$v10$$x2045-2322$$y2020 000874259 8564_ $$uhttps://juser.fz-juelich.de/record/874259/files/Invoice_2676177062.pdf 000874259 8564_ $$uhttps://juser.fz-juelich.de/record/874259/files/Invoice_2676177062.pdf?subformat=pdfa$$xpdfa 000874259 8564_ $$uhttps://juser.fz-juelich.de/record/874259/files/s41598-020-61373-9.pdf$$yOpenAccess 000874259 8564_ $$uhttps://juser.fz-juelich.de/record/874259/files/s41598-020-61373-9.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000874259 8767_ $$82676177062$$92020-02-26$$d2020-03-06$$eAPC$$jZahlung erfolgt$$p0905819e-93dc-49f5-8311-e 000874259 909CO $$ooai:juser.fz-juelich.de:874259$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)169878$$aForschungszentrum Jülich$$b0$$kFZJ 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)181055$$aForschungszentrum Jülich$$b1$$kFZJ 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171863$$aForschungszentrum Jülich$$b2$$kFZJ 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171204$$aForschungszentrum Jülich$$b3$$kFZJ 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166130$$aForschungszentrum Jülich$$b4$$kFZJ 000874259 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171865$$aForschungszentrum Jülich$$b5$$kFZJ 000874259 9131_ $$0G:(DE-HGF)POF3-131$$1G:(DE-HGF)POF3-130$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lSpeicher und vernetzte Infrastrukturen$$vElectrochemical Storage$$x0 000874259 9141_ $$y2020 000874259 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000874259 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000874259 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000874259 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000874259 915__ $$0StatID:(DE-HGF)1040$$2StatID$$aDBCoverage$$bZoological Record 000874259 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bSCI REP-UK : 2017 000874259 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000874259 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000874259 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000874259 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000874259 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000874259 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000874259 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000874259 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000874259 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000874259 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000874259 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000874259 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000874259 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000874259 9201_ $$0I:(DE-Juel1)IEK-12-20141217$$kIEK-12$$lHelmholtz-Institut Münster Ionenleiter für Energiespeicher$$x0 000874259 9801_ $$aAPC 000874259 9801_ $$aFullTexts 000874259 980__ $$ajournal 000874259 980__ $$aVDB 000874259 980__ $$aUNRESTRICTED 000874259 980__ $$aI:(DE-Juel1)IEK-12-20141217 000874259 980__ $$aAPC 000874259 981__ $$aI:(DE-Juel1)IMD-4-20141217
