A rechargeable Si–air solid state oxygen shuttle battery incorporating an oxide ion conductor†
Abstract
Herein, we report a new type of Si–air rechargeable battery incorporating an oxide ion conducting electrolyte, based on the oxygen shuttle concept. A cell designed in this manner and employing Ca stabilized ZrO2 exhibited stable charge–discharge over 20 cycles at 1073 K and achieved a discharge capacity of approximately 600 mA h gSi−1.
