· Na2 Ni1 O2

Sodium nickel oxide (Na₂NiO₂) is a mixed-metal oxide semiconductor with a layered crystal structure that combines sodium and nickel cations in an oxide framework. This compound is primarily of research interest as a potential cathode material for sodium-ion batteries and energy storage devices, where its mixed-valence transition metal chemistry offers electronic conductivity and electrochemical activity. Compared to lithium-ion alternatives, sodium-based systems present cost and abundance advantages, making materials like Na₂NiO₂ attractive for grid-scale energy storage and portable applications where lithium supply constraints are a concern.

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.
