Composites: An Amorphous Red Phosphorus/Carbon Composite as a Promising Anode Material for Sodium Ion Batteries (Adv. Mater. 22/2013)

Na-ion batteries now face the critical problem of lower energy density than Li-ion batteries, although they have gained recognition as promising next-generation batteries to replace Li-ion batteries. An amorphous red phosphorus/carbon composite anode material is for the first time examined as a solution to improve energy density, and shows remarkable electrochemical performance including high reversible capacity of 1890 mA h g−1. Further details can be found in the article by Kyu Tae Lee, Seung M. Oh, and co-workers on page 3045.
