| Abstract Scope |
Two-dimensional transition metal dichalcogenides [TMDs] offer unique properties for energy storage. Among them, 1T-phase titanium disulfide [1T-TiS₂] stands out for its high conductivity and catalytic activity. Here, bulk TiS₂ was synthesized via solid-state reaction [50 g batch scale], followed by organolithium exfoliation to yield ~5 g of 2D 1T-TiS₂ nanosheets per batch. These nanosheets were used to fabricate binder-free, self-standing electrodes and printable slurries. In Li–S batteries, 1T-TiS₂ cathodes achieved 900 mAh/gS with 75% retention over 100 cycles. In zinc-ion capacitors, specific capacitance reached 214.3 F/g and 116.4 mAh/g capacity. Dopamine-functionalized films formed a thin TiO₂ overlayer, improving oxidation resistance and enabling 96% retention after 10,000 cycles in aqueous supercapacitors. This work demonstrates a scalable route to integrate 1T-TiS₂ into hybrid energy storage systems, combining high electrochemical performance with additive manufacturing compatibility. |
