Indeed, electrolyte oxidation increases during charge (5 V vs Li|Li+) for decreased C rates, that is longer duration at high state-of-charges (SOC) , but effective protection and evidence for CEI formation is missing as no increase in Coulombic efficiencies is observed, even with literature-known electrolyte additives like vinylene carbonate, fluoroethylene carbonate, or ethylene sulfite in a highly concentrated base electrolyte (4.0 m LiPF6 in dimethyl carbonate) as reference. Via studying charged and pristine PEs by X-ray photoelectron spectroscopy, PF6−-graphite intercalation compounds and cointercalated solvent molecules are identified, while indications for CEI are absent within 1000 charge/discharge cycles. Nevertheless, a high capacity retention of ≈94% (referring to 0.1C) is demonstrated. Affirmed by Raman spectroscopy and scanning electron microscopy, the active material remains structurally stable, suggesting capacity fading to be dominated by resistance rise at the PE, likely due to an electronic contact resistance from active material grain boundaries and/or from the interface between electrode particles and the current collector in course of high volume changes; as systematically derived by impedance spectroscopy. 001048484 536__ $$0G:(DE-HGF)POF4-1223$$a1223 - Batteries in Application (POF4-122)$$cPOF4-122$$fPOF IV$$x0 001048484 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001048484 7001_ $$0P:(DE-Juel1)188450$$aPfeiffer, Felix$$b1 001048484 7001_ $$0P:(DE-HGF)0$$aRudolf, Katharina$$b2 001048484 7001_ $$0P:(DE-HGF)0$$aSutar, Pranti$$b3 001048484 7001_ $$0P:(DE-HGF)0$$aBaghernejad, Masoud$$b4 001048484 7001_ $$0P:(DE-Juel1)166130$$aWinter, Martin$$b5 001048484 7001_ $$0P:(DE-HGF)0$$aPlacke, Tobias$$b6 001048484 7001_ $$0P:(DE-HGF)0$$aKasnatscheew, Johannes$$b7$$eCorresponding author 001048484 773__ $$0PERI:(DE-600)3010017-3$$a10.1002/aesr.202400330$$gVol. 6, no. 3, p. 2400330$$n3$$p2400330$$tAdvanced energy & sustainability research$$v6$$x2699-9412$$y2025 001048484 8564_ $$uhttps://juser.fz-juelich.de/record/1048484/files/Adv%20Energy%20and%20Sustain%20Res%20-%202024%20-%20Haneke%20-%20Investigating%20the%20Existence%20of%20a%20Cathode%20Electrolyte%20Interphase%20on%20Graphite%20in.pdf$$yOpenAccess 001048484 909CO $$ooai:juser.fz-juelich.de:1048484$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 001048484 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)188450$$aForschungszentrum Jülich$$b1$$kFZJ 001048484 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166130$$aForschungszentrum Jülich$$b5$$kFZJ 001048484 9131_ $$0G:(DE-HGF)POF4-122$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1223$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vElektrochemische Energiespeicherung$$x0 001048484 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001048484 915__ $$0StatID:(DE-HGF)3001$$2StatID$$aDEAL Wiley$$d2024-12-05$$wger 001048484 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-08-08T17:09:31Z 001048484 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-08-08T17:09:31Z 001048484 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001048484 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Anonymous peer review$$d2024-08-08T17:09:31Z 001048484 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2024-12-05 001048484 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2024-12-05 001048484 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bADV ENERG SUST RES : 2022$$d2025-11-11 001048484 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2025-11-11 001048484 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2025-11-11 001048484 915__ $$0StatID:(DE-HGF)0112$$2StatID$$aWoS$$bEmerging Sources Citation Index$$d2025-11-11 001048484 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2025-11-11 001048484 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bADV ENERG SUST RES : 2022$$d2025-11-11 001048484 920__ $$lyes 001048484 9201_ $$0I:(DE-Juel1)IMD-4-20141217$$kIMD-4$$lHelmholtz-Institut Münster Ionenleiter für Energiespeicher$$x0 001048484 980__ $$ajournal 001048484 980__ $$aVDB 001048484 980__ $$aUNRESTRICTED 001048484 980__ $$aI:(DE-Juel1)IMD-4-20141217 001048484 9801_ $$aFullTexts
