Li-O 2 battery is the leading next-generation battery system, which is known for its extremely high theoretic specific energy. However, the Li metal used in Li-O 2 batteries suffers from low Li utilization and safety hazards. In this work, as an alternative to Li anode, Li 21 Si 5 powders, which are synthesized by an easy mechanical process, are incorporated into a Li-ion oxygen battery. The electrochemical property of the prepared battery and its cycling stability are investigated. Without electrochemical prelithiation, the pursuit of Li-Si alloy anodes in this study provides an easy and scalable strategy for preparing Li-ion oxygen batteries. [ABSTRACT FROM AUTHOR]
