Abstract

A practicable strategy has been developed to build a Li_xSi–O₂ battery using an in situ formed Li–Si alloy anode based on the decomposition of Li₃N pre-loaded in the cathode. The Li_xSi–O₂ battery has achieved more than 100 stable charge–discharge cycles with lower polarization than that using a lithium metal anode.
