“…66,67 In addition, the partial reduction of N-alkyl-N-methylpyrrolidinium ([C n mpyr] + ) cations is known to occur within the working potential range (0−1.5 V vs Li/Li + ). 49,[68][69][70] Therefore, even though the active material and Li + concentration are different from the previous study, 49 [FSI] composite electrodes in the solid state was also reported for the case of a graphite electrode. 49,53 This further strengthens the hypothesis that, regardless of the types of active materials, Li + -containing OIPCs are promising materials as solid electrolytes incorporated within an electrode, which can provide integrated Li + conducting pathways throughout the electrode layer, thereby facilitating the lithiation/delithiation reactions.…”

Silicon is one of the highest-capacity anode active materials and, therefore, its use in solid-state batteries (SSBs) is expected to provide both high energy density and safety. Although the creation of solid-state Si electrodes via a scalable method is important from the perspective of battery production, its effect on electrochemical performance has yet to be clarified for the electrodes containing Li+-doped organic ionic plastic crystals (OIPCs) as solid electrolytes. Here, we made various Si−OIPC composite electrodes using four electrode-preparation methods and measured their electrochemical performances to decipher the method−structure−property relationship for high-performing SSBs. The Si−OIPC composite electrode containing 50 mol% LiFSI in N-ethyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide ([C2mpyr][FSI]) showed the highest initial Coulombic efficiency and cyclability. Three out of four methods provided the Si−Li0.50[C2mpyr]0.50[FSI] electrodes with relatively large capacity retentions that were close to that of the Si electrode in a liquid electrolyte. Elemental analysis for the electrode cross-sections resolved the homogeneous distribution of Li0.50[C2mpyr]0.50[FSI], except for the one made by the drop-casting method, suggesting that three methods can establish the long-range ion-conduction network in the electrode to improve the electrochemical stability of Si during cycling. This study clarifies the importance of the OIPC-incorporation method in fabricating highly functional OIPC-based electrodes for SSBs.

This study focuses on electrochemical potential control and fabrication methods for various metal complexes and polycyclic aromatic hydrocarbons at solid-liquid interfaces, particularly using electrochemical scanning tunneling microscopy (EC-STM) and atomic force microscopy (AFM). The in situ observation of molecular assemblies and understanding of the phase transition dynamics and ligand exchange reactions at the molecular and/or submolecular levels provide information on functional molecular design and surface engineering. In addition, ionic liquids electrochemistry is summarized from the viewpoint of single-crystal electrochemistry.
