Dry-processable electrode technology presents a promising avenue for advancing lithium-ion batteries (LIBs) by potentially reducing carbon emissions, lowering costs, and increasing the energy density. However, the commercialization of dry-processable electrodes cannot be achieved solely through the optimization of manufacturing processes or modifications of existing electrode components. Therefore, material innovation is urgently required for each of the core components of dry electrodes: binders, conductive agents, and current collectors. This Review explores recent advancements in these components, delving into their physicochemical roles and contributions. We identify critical performance factors and propose design strategies aimed at improving the functionality of electrode components and the overall performance of dry electrodes. This Review provides insights into the material innovations required to overcome current limitations and drive the sustainable advancement of LIB technology through dry electrode processes.
