Preparation of Mesoporous Si@PAN Electrodes for Li-Ion Batteries via the In-Situ Polymerization of PAN

Abstract

(electrode), the first cycle coulombic efficiency of these electrodeswas still less than 50% without a pre-lithiation treatment. The results of an all-solid-state battery experiment confirmed that low firstcycle reversibility should be attributed primarily to mechanical pulverization of the internal porous structure of mp-Si particles.© 2015 The Electrochemical Society.
