Active Material Electrodes TRIZ Cases
- Graphite-Supported Fuel Cell Catalyst for Higher Metal Loading
A two-step polyol process builds an island catalyst structure on graphite, raising metal loading while limiting catalyst loss and preserving durability.
- Beta-Delithiated Nickel Oxide Cathode for Low-Gas High-Loading Batteries
A beta-delithiated layered nickel oxide cathode suppresses gas evolution and instability, enabling higher active-material loading and longer battery life.
- Two-Layer Graphite Anode Structure for Adhesion and Fast Charging
A two-layer graphite anode balances current-collector adhesion with high-rate charging by separating natural and artificial graphite roles.
- Silicon Anode Active Material Purification for Uniform Li-Ion Diffusion
Mixed-acid cleaning removes metal impurities from silicon anode material, improving lithium-ion diffusion and reducing short-circuit risk.
- Si Granulated Electrode Active Material With Low Residual Solvent
Limiting residual organic solvent in Si granulated active material helps preserve battery cycle characteristics without burdensome drying.
- Cathode Material Precursor Density Gradient for Lithium Diffusion
A denser core and lower-density surface improve lithium diffusion while limiting cracks, extending cycle life, and boosting thermal stability.
- Lithium Secondary Battery Grain-Size Matching for High Energy Density
Matching NCM and silicon-carbon crystal grain sizes helps raise energy density while limiting swelling, lithium loss, and cycle deterioration.
