Here, sieving carbon is selected as a model material to study the role of defects within closed pores in plateau sodium storage, considering that its pore forming and pore sealing by chemical vapor deposition are decoupled during material preparation. Specifically, vacancy-dominated defects are formed within closed pores by hydrogen reduction of porous carbon precursor and an identical external surface with deposited carbon covered is obtained by chemical vapor deposition. Such a vacancy-rich sieving carbon exhibits a high specific capacity of 470 mAh g<sup>−1</sup>, along with an increased plateau capacity and improved cycling stability, remaining 72.3 % of its initial capacity after 400 cycles (342 mAh g<sup>−1</sup>). A series of spectroscopic studies demonstrate that increased carbon vacancies promote the formation of sodium clusters with higher reversibility in closed pores.

The coating was fabricated by spray-coating a mixture of WMC and polydimethylsiloxane (PDMS) resin onto a PDMS-pretreated Al substrate. The resulting surface exhibited remarkable superhydrophobicity, with a water contact angle of 163° and roll-off angle of 2.8°.

The photothermal de-icing capability of the coating was assessed by monitoring the melting of frozen water droplets under simulated sunlight. The frozen droplets on the coated surface melted completely within 5 min 39 s, and the melted water easily rolled off. The outstanding anti-icing and de-icing performance of the coating is attributed to its hierarchical micro/nanostructure, which minimizes ice adhesion, and the superior photothermal efficiency of the WMC.
