A double trap: A hollow mesoporous carbon@titanium nitride (HMC@TiN) host has been designed and synthesized for loading 70 wt % of SeS₂ as a cathode material for Li–SeS₂ batteries (see picture). As a result of both physical and chemical entrapment by the hollow mesoporous carbon and TiN, the HMC@TiN/SeS₂ cathode showed high utilization of the active material and excellent cycling stability.

介孔碳@氮化钛空心球作为高级Li–SeS2电池的高效SeS2主体

一个双重陷阱：已经设计并合成了一种中空的中孔碳@氮化钛（HMC @ TiN）主体，以装载70 wt％的SeS ₂作为Li–SeS ₂电池的阴极材料（见图）。由于中空介孔碳和TiN的物理和化学截留，HMC @ TiN / SeS ₂阴极显示出活性材料的高利用率和出色的循环稳定性。
