“…A layer of TiO 2 was then coated on SiO 2 @SiO 2 /RF by a method developed by our research group . Urea was used as a nitridation reagent in the annealing process, during which the generated NH 3 gas could react with the amorphous TiO 2 and transform it into the TiN phase . At the same time, RF was fully carbonized by the treatment at 700 °C in N 2 .…”

The introduction of a certain proportion of selenium into sulfur-based cathodes is an effective strategy for enhancing the integrated battery performance. However, similar to sulfur, selenium sulfide cathodes suffer from poor cycling stability owing to the dissolution of reaction intermediate products. In this study, to exploit the advantages of SeS to the full and avoid its shortcomings, we designed and synthesized a hollow mesoporous carbon@titanium nitride (HMC@TiN) host for loading 70 wt % of SeS as a cathode material for Li-SeS batteries. Benefiting from both physical and chemical entrapment by hollow mesoporous carbon and TiN, the HMC@TiN/SeS cathode manifests high utilization of the active material and excellent cycling stability. Moreover, it exhibits promising areal capacity (up to 4 mAh cm ) with stable cell performance in the high-mass-loading electrode.
