ceramic

· JVASP-12151· NiH2O2

NiH2O2 is an experimental ceramic compound containing nickel, hydrogen, and oxygen phases. This material belongs to the family of layered nickel hydroxide-based ceramics, which are primarily investigated in electrochemistry and energy storage research rather than conventional structural engineering. The material shows potential for energy storage applications, particularly in battery and supercapacitor development, where its layered structure and compositional flexibility offer advantages for ion intercalation and charge storage compared to single-phase oxides.

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.
