Positive Electrodes TRIZ Cases
- Lithium Battery Composite Separator and Cathode Design
An organic/inorganic composite separator blocks dendrite growth while a mixed cathode stabilizes the crystal structure for high energy density.
- Nickel-Rich Cathode Particle Size Control for Battery Durability
Optimized particle size distribution reduces grain boundary interactions and structural disorder, improving charge/discharge efficiency.
- Manganese-Modified Nickel Hydroxide Positive Electrode for Alkaline Battery
A manganese-modified nickel hydroxide positive electrode active material with a conductive layer enhances capacity recovery in alkaline secondary batteries.
- TMH Cathode Single Plateau via Merged Ion Potentials
Transition metal hexacyanoferrate cathodes with matched ion potentials yield a single plateau charge curve.
- Carbon-Coated Active Material Composite for High-Speed Lithium-Ion Batteries
A carbon-coated active material composite with a net-shaped film structure resolves the trade-off between electron conductivity and lithium ion migration speed.
- Fluorine-Coated Lithium Nickel Oxyfluoride Cathode for Cycle Stability
A fluorine-containing coating stabilizes the layered positive electrode active material surface to suppress side reactions.
- Lithium Transition Metal Oxide with Tungsten and Rare-Earth Coating
Rare-earth compound particles adhere to recesses between primary particles, suppressing surface alteration and cracking during high-temperature cycles.
