    Abstract

    A new method of preparing anodes for rechargeable lithium batteries using silicon monoxide and Li powder is reported herein. Although SiO anode materials show good cyclability and high capacity, their initial irreversibility limits their commercial use. In this study, we present a double-layered anode in which the Li powder is partly composed of SiO to compensate for the initial irreversible loss. The efficiencies in the 1st and 2nd cycles of this doubled-layered cell were ~90.17% and 98.50%, respectively. This double layered anode approach represents a breakthrough that enables the use of SiO in high-capacity Li rechargeable batteries.
