Metal Organic Frameworks Derived Hierarchical Hollow NiO/Ni/Graphene Composites for Lithium and Sodium Storage
TL;DR: Li et al. as discussed by the authors designed a hierarchical hollow ball-in-ball structure of NiO/Ni/Graphene composites, which not only mitigates the volume expansion of the NiO during the cycles but also provides a continuous highly conductive graphene matrix to facilitate the fast charge transfer and form a stable SEI layer.

Formation of Hierarchical Cu-Doped CoSe2 Microboxes via Sequential Ion Exchange for High-Performance Sodium-Ion Batteries.
TL;DR: A two-step ion-exchange method is developed to synthesize hierarchical Cu-doped CoSe2 microboxes assembled by ultrathin nanosheets using Co-Co Prussian blue analogue microcubes as the starting material, which exhibit enhanced sodium storage properties in terms of good rate capability and excellent cycling performance.
