· JVASP-33292· H2PbO2

H₂PbO₂ (lead oxyhydroxide) is an inorganic ceramic compound containing lead, oxygen, and hydrogen, typically encountered in lead chemistry and electrochemistry research contexts. This material is primarily of interest in battery technology—particularly as a component in lead-acid battery positive plates and in specialized electrochemical applications where lead oxide chemistry is exploited. While not a mainstream structural ceramic, H₂PbO₂ represents a niche material for engineers working with legacy battery systems, corrosion chemistry, or experimental energy storage devices where lead-based redox reactions are intentional; modern applications are limited due to lead toxicity concerns and regulatory restrictions in many regions.
