Abstract:Silicon (Si) is a promising anode material due to its high theoretical capacity and abundant presence as the second most common element in the earth's crust. However, the formation of an unstable solid-electrolyte interphase (SEI) and significant volume expansion during lithiation result in structural degradation, leading to a decrease in the cycle life for Si-based anodes. This paper reports on the electrochemical performance of the silicon/graphite (Si/Gr) electrodes coated with nanometer-thick ZnO layers pr… Show more
