Li‐Ion Batteries: SnO₂ Anode Surface Passivation by Atomic Layer Deposited HfO₂ Improves Li‐Ion Battery Performance (Small 14/2014)

A facile approach is demonstrated by H. N. Alshareef and co-workers for the fabrication of α-Fe2O3 mesocrystals/graphene nanohybrids by self-assembly of FeOOH nanorods as the primary building blocks on graphene under hydrothermal conditions, accompanied and promoted by concomitant phase transition from FeOOH to α-Fe2O3. On page 2849, the nanohybrids with unique sufficient porous structure and high electrical conductivity allow effective ion and charge transport in the whole electrode, which shows superior electrochemical performances.
