This study proposes a novel solid-state storage strategy, which involves loading ammonia borane (AB) and a cobalt catalyst into a graphene aerogel (AB@Co/RGOA), to regulate hydrogen generation via water-mediated hydrolysis. Characterization reveals that Co nanoparticles are uniformly dispersed on the graphene aerogel, while AB is effectively encapsulated within the structure to form a bulk solid composite. This AB@Co/RGOA system enables switchable hydrogen production, which can be precisely initiated and halted by modulating the water supply to the aerogel. Furthermore, the Co-decorated RGO framework (Co/RGOA) remains intact after AB is fully consumed and can be reloaded with fresh AB for subsequent cycles. The catalyst exhibits favorable catalytic activity toward AB hydrolysis with a turnover frequency (TOF) of 109.63 min⁻¹ at 25 °C. Moreover, the catalyst retains over 90% of its initial activity after five cycles of reuse.

However, critical challenges persist, including low electrical conductivity, structural instability arising from reversible bond cleavage, and inefficient utilization of electrochemically active sites. This study employs a stable dioxane-linked COF (DOL-COF) in terms of structure as the anode material and implements an interfacial engineering strategy to address these limitations. The approach enables orientation-designed and π-π interaction-driven in-situ growth of DOL-COF nanosheets on reduced graphene oxide (rGO) scaffolds. Electrochemical analysis identifies inefficient charge-mass transport within DOL-COF as the primary kinetic bottleneck. Theoretical calculations elucidate charge transport characteristics and reveal a tripartite lithium storage mechanism in DOL-COF, comprising Faradaic intercalation, pseudocapacitive redox storage, and non-Faradaic capacitive storage. This mechanistic insight guides the optimization of charge-mass transport via interfacial engineering. The resultant DOL-CRG-60 nanocomposite achieves electrode-mass-based reversible capacities of 1289 mAh g⁻¹ at 0.1 A g⁻¹ and 291 mAh g⁻¹ at 5.0 A g⁻¹, with 94.5% capacity retention after 3000 cycles at 5.0 A g⁻¹. The DOL-CRG-60 nanocomposite delivers an effective specific capacity of 1425 mAh g⁻¹, corresponding to approximately 84.5% utilization of Faradaic active sites. These enhancements originate from synergistic optimization of electronic conductivity, ion/electron transport pathways, and active-site accessibility, as evidenced by comparative electrochemical analyses.
