天然硫化矿成本低廉、电化学活性优异，若能短流程地运用于储钠领域，对于矿物材料及钠离子电池意义重大。然而，硫化物在储钠过程中面临体积膨胀、传质速率慢等问题，研究表明碳复合能有效解决此类问题。但天然硫化矿难以通过常规碳复合手段形成结构稳定的复合物，致使其电化学性能不佳。基于此，前期研究发现在硫化物与碳界面处进行化学键构筑，有效提升了界面结构稳定性。因此，若将天然硫化矿与碳进行界面键合，理论上能提升其储钠性能。本项目以天然黄铁矿为研究对象，通过短流程原位氧化形成FeS2/FeOx异质结，键合功能化碳片，从而构筑界面金属-氧-碳化学键，系统地研究其成键机理、储钠机制及分子层面理化优势，形成高效界面筑键策略，获取结构稳定的矿物基复合材料，并进行实际应用储钠性能探究，最终为矿物基材料的界面化学键设计提供理论支撑。

Owing to their low-cost, excellent electrochemical activity, sulfide minerals have captured numerous attentions. Through the short-running process, they may be utilized as sodium-ions storage materials, facilitating the development of mineral application and sodium ions batteries (SIBs). However, they still suffer from some issues in cycling, including volume expansion and sluggish kinetics. According to the previous reports, carbon complexing have been deemed as the effective manner, whereas it is of no effect for sulfide minerals, resulting in the inferior ions-storage ability. Thus, in our earlier works, the interfacial chemical bonds were introduced into metal-sulfide with carbon, strongly improved the structural stability. Theoretically, the expected bonds in sulfide minerals/carbon would be conductive to the improvement of ions-storage capability. Hence, through the short-running process, nature pyrite would be used to obtain metal-sulfide FeS2. Then, the heterojunction could be formed through the controlling of surface component. More importantly, after the optimizing of function groups about carbon, the metal-oxygen-carbon bonds could be constructed between carbon and heterojunction. Meanwhile, their formed mechanism, ions-storage traits and the molecular-level advantages are systematically investigated. Finally, the available bonding strategies are mastered, and the resulted mineral-based SIBs materials with considerable properties are practically explored. This studies would be anticipated to provide the theoretical support for interfacial chemical bonds designing of mineral-based materials.
