摘要: In order to address the increasing demands for clean energy, it is highly desirable to explore new electrode materials to improve the efficiency of lithium ion batteries (LIBs). In this work, we report the successful synthesis of a crystalline (H3O) 2 (enH2) Cu8Sn3S12 material via a surfactant-thermal strategy. The crystal structure analysis shows that the as-prepared chalcogenide has 3D interconnected channels occupied by disordered H2en2+ and H3O+. Taking advantage of porous structures and H2en2+ and H3O+ as stabilizers,(H3O) 2 (enH2) …
