Laurate-intercalated films of ZnAl layered double hydroxide (ZnAl-LDH–laurate) were fabricated by anion exchange laurate with ZnAl-LDH–NO3− on a porous anodic alumina/aluminum (PAO/Al) substrate. The presence both microscale and nanoscale hierarchical structures (see SEM image) makes the film superhydrophobic, thus it has much better corrosion resistance than PAO alone or films.

Abstract Layered transition metal oxide P2‐Na 2/3 Ni 1/3 Mn O 2 usually suffers from large‐volume phase transitions and different Na‐vacancy ordering during sodium (de)intercalation, incurring rapid capacity decline poor rate capability. Herein, an effective strategy based on synergetic effect of selected multiple ions is designed for P2‐type cathodes with improved performance. The role tetravalent titanium provides high redox potential, inactive divalent magnesium stabilizes the structure,...
