ceramic

· NaMnO2

NaMnO2 is an inorganic ceramic oxide compound composed of sodium, manganese, and oxygen, belonging to the family of layered metal oxides. It is primarily studied and used as a cathode material in sodium-ion batteries, where its crystal structure enables efficient sodium-ion intercalation and extraction during charge-discharge cycles. NaMnO2 offers advantages over lithium-based systems in applications requiring lower cost, improved safety, and use of abundant raw materials, making it particularly attractive for large-scale energy storage and stationary power applications where sodium-ion technology is becoming commercially viable.

Regulatory Screening

Environmental

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.
