| Abstract | We introduce a novel ambient hydrolysis deposition (AHD) methodology that, for the first time, employs sequential water adsorption followed by a hydrolysis reaction to infiltrate tiny SnO2₂ particles inside nanopores of mesoporous carbon in a conformal and controllable manner. The empty space in the SnO2₂/C composites can be adjusted by varying the number of AHD cycles. A SnO2₂/C composite with an intermediate SnO2₂ loading exhibits an initial specific delithiation capacity of 1054 mAh/g as an anode for Li-ion batteries (LIBs). The capacity contribution from SnO2₂ in the composite electrode of SnO2₂ (1494 mAh/g) when considering that both Sn alloying and SnO2₂ conversion reactions are reversible. The composite shows a specific capacity of 573 mAh/g after 300 cycles, one of the most stable cycling performances for the SnO2₂/mesoporous carbon composites. Enabled by the controllable AHD coatings, our results demonstrated the importance of the well-tuned empty space in nanostructured composites to accommodate the expansion of electrode active mass during alloying/dealloying and conversion reactions. |
