Sulfur Compounds TRIZ Cases

High-valence cation and anion doping with a selenium surface layer stabilizes nickel-rich cathodes, limiting oxygen release and interface degradation.

High-valence cation and anion doping plus selenium and conductive coatings stabilize nickel-rich cathodes and curb oxygen release and side reactions.

A solvent-free low-temperature route uses mechanochemical, vacuum, or electron-beam activation to raise crystallinity and room-temperature ionic conductivity.

Iodine doping in an SO2-based inorganic electrolyte forms a protective lithium interface that suppresses dendrites and lowers overvoltage.

A carbon nanostructure and iron oxyhydroxynitrate coating boosts sulfur cathode conductivity and adsorbs polysulfides to improve discharge stability.

Organic molecules bond to sulfur particle surfaces to improve polar dispersibility, suppress polysulfides, and stabilize Li-S electrode capacity.

Carbon nanostructures and iron oxyhydroxynitrate raise cathode conductivity and adsorb polysulfides, improving Li-S battery capacity and stability.

Water vapor injection upstream of SO3 absorption boosts steam recovery while keeping sulfuric acid mist and corrosion under control.

Synchronized converter heating keeps the catalyst at 200-250°C during SO2 pauses, preventing degradation and avoiding frequent line blowing.

Wet sulfur-bearing feed and 22-40% oxygen produce dilute sulfuric acid without drying towers, cutting cost and NOx emissions.

Acid treatment purifies phosphogypsum and recycles P2O5-bearing liquor to raise phosphorus yield and produce cement-grade calcium sulfate.

Pure oxygen in the reduction chamber boosts spent acid regeneration capacity while limiting pressure drop, NOx swings, and unstable combustion.

Water tube inter-bed boilers with bypass mixing recover heat and control catalyst inlet temperature without costly steam superheaters.

Acid purification and P2O5 liquor recycling remove phosphogypsum impurities while raising phosphorus yield and producing clinker-grade calcium sulfate.

Atmospheric plasma coats sulphur particles with conductive layers to improve Li-S transport, limit shuttling, and extend cycle life.

Existing sulfurous acid generators convert 60% or less of sulfur; secondary burning and venturi mixing raise conversion above 90%.

Oxygen-enriched oxidation stabilizes sulfur dioxide production, reducing inert nitrogen, energy use, and plant volume in sulfuric acid recovery.
