SiO-induced thermal instability and interplay between graphite and SiO in graphite/SiO composite anode

Abstract

SiO is an adequate anode material for next generation lithium-ion batteries, but little is known about its aging mechanism. Here, the authors report thermal instability of the graphite/SiO composite anode induced by the accelerated loss of lithium from SiO and have elucidated the interplay between graphite and SiO.
