Propylene carbonate is employed as a reference electrolyte solvent. The physicochemical properties of these electrolyte systems are determined experimentally and further calculated using our developed computational model. Besides, in‐silico investigations are used to reveal valuable insights into the molecular interactions of the electrolyte components, such as self‐diffusion coefficients and radial distribution functions. Furthermore, the suitability of lactone‐based electrolytes for electrochemical applications is demonstrated by their promising rate capability and cycling stability over 200 cycles in graphite half‐cells, especially with 1 M LiTFSI and 2 wt% vinylene carbonate, together with their favorable performance on lithium iron phosphate. An excellent capacity retention achieved in a full‐cell configuration (> 80% after 200 cycles) further validates the potential of lactones as battery solvent alternatives, with GVL standing out due to its bio‐based origin. bio‐based electrolyte graphite imide lactone lithium‐ion battery article Schulze, Wanja Timm Author aut Institute of Physical Chemistry Friedrich Schiller University Jena Jena Germany (DE-588)1323071318 Song, Zihan Author aut Institute for Technical Chemistry and Environmental Chemistry Friedrich Schiller University Jena Jena Germany Center for Energy and Environmental Chemistry Jena (CEEC Jena) Friedrich Schiller University Jena Jena Germany (DE-588)1384742565 Croy, Alexander Author aut Institute of Physical Chemistry Friedrich Schiller University Jena Jena Germany (DE-588)142054291 Gómez Urbano, Juan Luis Author aut Institute for Technical Chemistry and Environmental Chemistry Friedrich Schiller University Jena Jena Germany Center for Energy and Environmental Chemistry Jena (CEEC Jena) Friedrich Schiller University Jena Jena Germany (DE-588)1333821840 Gräfe, Stefanie Author aut Center for Energy and Environmental Chemistry Jena (CEEC Jena) Friedrich Schiller University Jena Jena Germany Institute of Physical Chemistry Friedrich Schiller University Jena Jena Germany Fraunhofer Institute for Applied Optics and Precision Engineering Jena Germany (DE-588)130290882 Balducci, Andrea Author aut Institute for Technical Chemistry and Environmental Chemistry Friedrich Schiller University Jena Jena Germany Center for Energy and Environmental Chemistry Jena (CEEC Jena) Friedrich Schiller University Jena Jena Germany (DE-588)106404932X Friedrich-Schiller-Universität Jena Chemisch-Geowissenschaftliche Fakultät host institution his 5:1:e70051<1 Battery Energy 2768-1688 2768-1696 dbt_mods_00068848 https://www.db-thueringen.de/receive/dbt_mods_00068987 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00070364/BTE2_BTE270051.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00068987.png preview https://www.db-thueringen.de/receive/dbt_mods_00068987 uri
