Carbon Compounds TRIZ Cases
- Silicon Anode Coating for Battery Volume Expansion
Silicon particles coated with silicon carbide and continuous carbon phases buffer volume expansion during lithiation to maintain mechanical stability.
- Graphene Manufacturing via Dual Oxidation for Resistivity Control
Sequential oxidation with varying strengths precisely regulates oxygen concentration, enabling reduced graphene resistivity within 1.45–150Ω/cm.
- Carbon Plate with Plant Fiber and Zeolite for Formaldehyde Absorption
A carbon plate combines plant fiber, zeolite powder, and tea stem residue to create a composite structure.
- Positive Electrode Active Material Layer for Fast-Charging Secondary Batteries
A positive electrode active material layer uses reduced graphene oxide to enhance electrical conductivity and stability.
- Graphite Flake Fabrication via Mesophase Pitch Slurry Casting
Mesophase pitch slurry casting yields oriented graphite flakes, avoiding expensive natural graphite purification and high temperature processing.
- Coal Upgrade Plant Mercury Removal via Pulverized Coal Adsorption
Pulverized coal with high specific surface area adsorbs mercury, eliminating separate denitration apparatuses.
- Plant-Derived Porous Carbon for Lithium-Sulfur Battery Sulfur Retention
Sub-4 μm plant-derived porous carbon retains sulfur within optimized voids, resolving the trade-off between high utilization and cycle stability.
- Selective Acetylene Oxidation Catalyst for Ethylene Purification
Metal oxide catalyst selectively oxidizes acetylene to carbon monoxide or dioxide, reducing concentration below 10 ppm without energy-intensive distillation.
- Binder-Free Coal Briquetting for Activated Carbon
Briquetting pulverized coal without binders avoids pore blockage and harmful residues while maintaining briquette strength.
