Iron Cyanides TRIZ Cases
- Carbon Nanotube Battery Electrode for Ultra-Fast Charge Retention
A binder-free carbon nanotube network disperses nanoscale active particles to sustain high energy density and capacity at ultra-fast charging.
- Prussian White Synthesis with Particle and Vacancy Control
Controlled formic acid decomposition and staged nucleation produce Prussian White with low vacancies, tunable particle size, and high tap density.
- Prussian-Blue Cathode Composition for Stable Sodium-Ion Battery Storage
Alkali-metal doping and pH control help Prussian-blue cathodes resist moisture uptake and preserve cycling and rate performance after storage.
- Prussian White Cathode Particle Control for Moisture Stability
Controlled Prussian white particle size and surface area reduce moisture-driven Na-loss and capacity fading in sodium-ion cathodes.
