· JVASP-13014· Na5Co2S5

Na5Co2S5 is a ternary metal sulfide compound combining sodium, cobalt, and sulfur, representing a mixed-metal chalcogenide in the research phase rather than an established commercial material. This compound family is being investigated for energy storage and electrochemical applications, particularly in sodium-ion battery systems and solid-state electrolyte development, where the combination of alkali metal and transition metal sulfides offers potential advantages in ionic conductivity and redox activity. The material would appeal to researchers and engineers exploring next-generation battery chemistries as an alternative to conventional lithium-based systems, leveraging sodium's abundance and cobalt's electrochemical versatility.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
