A highly ordered open-pore hybrid film was fabricated by controlling the substrate roughness and wettability. The composite with different wettability on the two side resulted in an attractive unidirectional water-penetration function (see figure).
A new dual-salt liquid electrolyte is developed that enables the reversible operation of high-energy sodium-metal-based batteries over a wide range of temperatures down to −50 °C.
