Abstract

Abstract: Herein we report the fabrication, optimization, and characterization of inkjet-printed thin film silicon anodes for lithium-ion batteries using commercial silicon nanoparticles. By comparing four different polymer binders, we demonstrate the critical role of binder on achieving good electrochemical performance of inkjet-printed silicon electrodes. Inkjet-printed silicon nanoparticle electrodes with conductive polymer PEDOT:PSS binder exhibit superior performance and durablity, with a capacity retention of over 1000 cycles at a depth-of-discharge of 1000 mA h g −1 . The working mechanism of the impact of the binders on inkjet-printed silicon electrodes is investigated and explained in detail via various characterization techniques, including scanning electron microscopy, Raman and infrared spectroscopy. Graphical abstract: Highlights: Silicon nanoparticle anodes for lithium-ion batteries were fabricated by inkjet printing. The electrochemical performance of silicon anodes printed with different polymer binders was investigated. The conductive polymer, PEDOT:PSS, showed the most stable cycling performance, with over 1000 cycles at a depth-of-discharge of 1000 mA h g −1 .
