Energetic Zinc Ion Chemistry: The Rechargeable Zinc Ion Battery

摘要

Energy-storage devices are now powering our world. An ideal energy-storage device that is characterized by high capacity, fast charge/discharge capability, safety, environmental friendliness, and low cost is of vital important for today's society. Our society has been seeking such ideal devices for various applications such as consumer electronics, electric vehicles, transportation, and military demands. However, existing aqueous energetic batteries or power-type supercapacitors are far from achieving the final goals. Herein we report a unique zinc ion battery chemistry for the preparation of a new safe and environmentally friendly zinc ion battery. The zinc ion battery can deliver a high capacity and can be charged or discharged within 30 seconds.
