Rechargeable Batteries: Formation of Septuple‐Shelled (Co2/3Mn1/3)(Co5/6Mn1/6)2O4 Hollow Spheres as Electrode Material for Alkaline Rechargeable Battery (Adv. Mater. 34/2017)

In article number 1700550, multi-shelled hollow spheres with controllable shell numbers up to septuple shells are prepared for the first time by Ranbo Yu, Yu Zhang, Dan Wang, and co-workers, by adjusting the crystalline rate of the product. Used as the electrode material for alkaline rechargeable batteries, the unique multi-shelled hollow structures demonstrate many benefits for the electrochemical process.
