“…Such systems are highly desirable for ensuring sustainable current supply from intermittent renewable energy sources (e.g., solar, wind), as well as for peak-shaving demands. 5,6 As these systems are supposed to store and supply an extensively large amount of energy (tens to hundreds of MW), 7 they require the use of huge quantities of electroactive materials. Hence, only abundant and cost-effective elements should be considered.…”

Among the examined organic electrodes for aqueous mono and multivalent ions batteries, polyimide is considered a promising candidate because of its high capacity and good cyclability in different electrolyte solutions. While most of the studies so far were focused on the energetic performance of polyimide anodes, much less is known about their charge storage mechanism and particularly how such electrodes are affected by the solvation properties of the inserted cations. Using in situ EQCM-D, a direct assessment of the cationic fluxes and their hydration shells inserted/extracted to/from PI electrodes upon potential application was performed for a large variety of mono and multivalent cations. Our observations demonstrated a pronounced withdrawal of water molecules from the polymeric electrodes during insertion of chaotropic cations and significantly less water withdrawal upon insertion of kosmotropic cations. These findings are well correlated with the capacity and the rate capability of the polyimide electrodes in the examined systems and shed light on their charge storage mechanism.

“…In addition, the current trial-and-error methods fail to establish a comprehensive understanding of the battery-fading mechanisms and the side reactions within them during operation in correlation to the chemical and physical properties of LIG. [125][126][127][128][129] The analysis of structural evolution, bonding, surface functionalities, and composite behavior by in situ characterization techniques is lacking in the case of LIG. Here, in situ studies during battery cycling are vitally important.…”

Synthesis of 3D graphene by laser irradiation has emerged as a promising approach due to its multifunctionality, cost effectiveness, and simplicity. Herein, the emerging applications of laser‐induced graphene (LIG) in batteries are focused on. This type of 3D graphitic carbon offers several advantages, including 1) binder‐free self‐supported electrode configuration, 2) high electrical and ionic conductivity, 3) hierarchical porosity, and 4) controllable composition upon laser exposure. A comprehensive review of the current status of LIG synthesis and its development for battery applications is discussed. This includes using LIG as an electrode for lithium‐ and sodium‐ion batteries, a current collector for lithium‐metal batteries, an electrocatalyst for metal–air batteries, and a host and interlayer for lithium–sulfur batteries. Finally, the article concludes by giving the authors’ perspectives and outlook for developing this class of carbon materials for advanced battery systems.

The optimization of the calendering process represents one of the key tasks for tuning the lithium‐ion battery performance. In this study, we present a systematic statistical‐based study of the three main calendering parameters (namely, the applied pressure, roll temperature, and line speed) effect on the porosity, electrode mechanical properties and electronic conductivity. Our work main goal is to understand how by changing the calendering parameters, the electrode properties can be tuned and up to which degree they determine the electrode capacity of Li(Ni0.33Mn0.33Co0.33)O2‐based cathodes. The statistical tools used for the analysis were the analysis of the covariance (ANCOVA), the principal components analysis (PCA), and the unsupervised machine learning k‐means clustering algorithm. Our results showed that while porosity and the mechanical properties depend mainly on the applied pressure, the electrode's conductivity correlates mainly with the temperature. All of them were found to influence the cathode's capacity (at a rate equal to C), being the best condition applied pressures between 60 and 120 MPa and roll temperatures between 60 and 75 °C.
