Electrode Manufacturing Processes TRIZ Cases
- High-Nickel Cathode Material With Surface Aluminum Doping
Surface aluminum doping creates a concentration gradient that stabilizes high-nickel cathodes under overcharge and high-temperature use.
- Nano-Engineered Battery Coatings for Interface Stability
Ultrathin ALD-style coatings block electrode-electrolyte side reactions, limiting resistance growth while preserving ion transport and cycle life.
- Lithium-Ion Cathode Relithiation Using Reusable Ionic Liquids
Ionic-liquid relithiation restores spent lithium-ion cathodes at 100-300°C, preserving structure while enabling solvent reuse.
- Aluminum Electrode Oxide Removal in Ionic Liquid Under Nitrogen
Ionic-liquid soaking under nitrogen removes oxide from aluminum electrode sheets while limiting residual moisture and re-oxidation.
- Laser Separator Cutting for Wide, Fast-Moving Electrode Stacks
A scanned laser and end mirror cut wide or fast-moving laminated separators precisely while reducing mechanical wear and installation space.
- Follow-Up Receiving Module for Continuous Electrode Plate Cutting
A reciprocating sliding table follows the cut path to receive electrode plates continuously, improving cutting quality and preventing deformation.
- Coating Die Head Position Sensing for Stable Roll Coating
Real-time level and range sensing tracks die head gap and parallelism to keep roll coating stable and prevent material damage.
- Dual-Function Current Collector for In Situ Lithium Deposition
In situ lithium deposition between a current collector and protective layer cuts excess lithium use and blocks dendrite-driven internal shorts.
- Hybrid Li-S Cathode Composition for Higher Energy Density
A sulfur-intercalation cathode cuts inactive carbon and porosity to raise Li-S battery gravimetric and volumetric energy density.
- High-Nickel Cathode Material With Boron for Heat-Stable Capacity
Boron-added high-nickel cathode particles balance battery capacity and heat stability through layered oxide composition and controlled porosity.
- Electrode Groove Laser Processing for Lower Reaction Resistance
Short-pulse laser grooves create nanostructures that improve electrolyte permeation and lower reaction resistance in battery electrodes.
- Bobbin Winding of Electrode-Connecting Film to Minimize Electrode Loss
Automating bobbin-mounted electrode-connecting film and tape attachment reduces splicing waste, improves work efficiency, and avoids electrode defects.
- Rotating Roller Laser Marking for Precise Electrode Plate Processing
A roller-mounted laser tracks moving electrode plates to improve marking precision and speed without buffer-based stop-start processing.
- Pattern Jig Brush Cleaning for Laser Notching Contamination
Rotating brushes and vacuum suction clear heat-generated fumes and particles from laser-notched pattern jigs without manual cleaning.
- Stacked Electrode Lead Gripper for Low-Resistance Pouch Cell Contact
A stacked current and voltage terminal assembly improves pouch-cell lead contact area and reliability while reducing resistance and charging heat.
