Navigating the Carbon Maze: A Roadmap to Effective Carbon Conductive Networks for Lithium‐Ion Batteries

Abstract

Abstract Conductive networks are integral components in Li‐ion battery electrodes, serving the dual function of providing electrons to the active material while its porosity ensures Li‐ion electrolyte accessibility to deliver and release Li‐ions, thereby ultimately determining the electrochemical performance of the battery. In the realm of academic research, the task of fabricating an electrode endowed with an effective conductive network has emerged as a daunting challenge, profoundly influencing a researcher's ability to showcase the intrinsic electrochemical performance of an active material. In the diverse landscape of conductive additives for battery electrodes, researchers are faced with a myriad of options when deciding on the appropriate additive and optimal electrode preparation methodology. This review seeks to provide a fundamental understanding and practical guidelines for designing battery electrodes with effective conductive networks across various length scales. This involves the meticulous selection of specific carbon conductive additives from the plethora of options and the exploration of methods for their effective integration into the electrode, all tailored to the unique characteristics of the active materials and the specific research objectives.
