· JVASP-137023· MnNiO4

MnNiO4 is a mixed-metal oxide ceramic compound combining manganese and nickel oxides, belonging to the spinel or related oxide ceramic family. This material is primarily explored in electrochemistry and energy storage research, particularly for battery cathodes, supercapacitor electrodes, and oxygen evolution catalysts, where its mixed-valence transition metal composition enables favorable electron transfer and ion transport. While not yet a mainstream commercial ceramic, MnNiO4 represents a promising alternative to single-metal oxides in energy applications where cost-effectiveness and electrochemical activity are priorities over extreme hardness or thermal stability.

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.
