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