Abstract
Micrometre-sized electroactive particles with high tapping density show significant potential for commercial application since they effectively alleviate low Coulombic efficiency and excessive solid electrolyte interphase (SEI) issues brought by nanostructures. Furthermore, optimizing the electrode architecture using novel design concepts can improve the energy density. Beyond the electrode material structure design strategy, binder plays a vital role in providing the mechanical stability and regulating the charge transport. This highlight presents the latest development to design high-capacity batteries by optimizing the binder structures in electrodes and emphasizes the significance of binder design for further commercial application.
