Abstract
Silicon (Si)-based anodes are promising candidates for high-energy-density lithium-ion batteries (LIBs). However, their practical application is hindered by poor electrode integrity and unstable electrochemical performance caused by large volume changes during cycling. In this study, we design a multifunctional polymer binder exhibiting strong adhesion and electric conductivity for SiOx/graphite composite electrodes.
This binder enables uniform dispersion of active materials while providing high adhesion and conductivity, therby facilitating efficient ion/electron transport within the electrode. As a result, SiOx/graphite composite electrodes demonstrate improved cycling stability compared to PAA-based electrodes.
These results highlight the critical role of binder design in stabilizing Si-based anodes and provide an effective strategy for enhancing the electrochemical performance of high-energy-density LIBs.
