Electrode Rolling/Calendering TRIZ Cases
- Electrode Assembly Opening Layout for Current Collector Durability
Specific spacing between electrode opening edges buffers calendering and abuse loads, reducing current collector tearing and detachment.
- Composite Battery Substrate With Rough Porous Layers for Adhesion
A rough porous fiber-mat substrate with metal layers improves active-layer adhesion and conductivity while reducing delamination in lithium batteries.
- Intermediate Substrate Powder Transfer for Uniform Dry Printing
An intermediate transfer substrate enables high-speed dry powder deposition with better layer uniformity, finer features, and less smoothing.
- Dry Battery Electrode Coating to Suppress Side Reactions
A catecholamine surface layer on active material and binder suppresses side reactions and irreversible capacity loss in dry lithium battery electrodes.
- Electrode Roll Mapping for Cell-Level Defect Traceability
Roll-map and cell-ID matching traces each notched electrode back to its source position, enabling cell-level defect isolation and less roll waste.
- 3D Battery Current Collectors With Controlled Porosity
Continuous electrochemical deposition forms porous 3D battery current collectors that lower resistance and support thick electrodes with longer cycle life.
- Battery Current Collector Foil Roughening for Coating Adhesion
Heat treatment and mechanical roughening of battery current collector foil improve coating adhesion, cycle retention, and assembly durability.
- Electrode Plate Pressing Measurement for Battery Loading Accuracy
Measures electrode properties before and after pressing to calculate coating stretch and loading loss, improving battery capacity control.
- Textured Lithium Foils for Dendrite-Stable Metal Anodes
Controlled {110}/{100} surface texturing in Li or Na foils suppresses dendrites and improves cycle stability in metal anodes.
- Secondary Battery Electrode Bonding With Fibrous Dry Binder
Dry mixing and heat-pressing anchor active material into a softening metal foil, raising peel strength without increasing penetration resistance.
- Crowned Rolling Roll for High-Density Battery Electrode Sheets
A crowned rolling roll concentrates pressure at the sheet center to raise cathode mixture density while reducing electrode breakage.
- Multilayer Electrode Transfer Process for Thickness and Bonding Control
Pre-formed active layers on release films enable roll-to-roll transfer with tighter thickness control and stronger electrode bonding.
- Electrode Plate Measurement for Pressing-Induced Loading Loss
Measures electrode properties before and after pressing to calculate elongation-driven loading loss and keep battery capacity within spec.
- Dry Electrode Film With Super-Fibrillized Binder for Low ESR
Super-fibrillized binder and conductive additives enable thinner dry electrode films with lower ESR while preserving mechanical stability.
- Dry Electrode Composition for Flexible Solid-State SOC Tracking
Cold-ground binder and staged active-material mixing create a flexible dry electrode that improves solid-state battery safety and SOC tracking.
- Dry Electrode Film Trimming With Vision-Based Width Alignment
Vision-guided trimming knives adjust free-standing film width and position in real time to stabilize dry electrode lamination on current collectors.
- Dry Electrode Extrusion With Sensor Feedback for Uncoated Width Control
An adjustable feeding shutter and sensor feedback control uncoated width in dry electrode extrusion, improving capacity, energy density, and safety.
- Dry Positive Electrode Lamination for Safer Solid-State Batteries
A dry-mixed positive electrode layer improves solid-state battery safety while preserving flexibility and state-of-charge tracking.
- Electrode Plate Pressing With Feedback-Controlled Uncoated Heating
Real-time temperature feedback keeps the electrode plate uncoated part within range during IHA, preventing breakage and stabilizing pressing quality.
- Multi-Roll Electrode Calendering for Thin Battery Plate Thickness Control
Staged main and sub-roll compression with thickness and temperature sensing improves thin electrode plate uniformity while reducing wrinkles and breakage.
- Electrode Lamination Roll Control for Uniform Active Material Thickness
Adjustable laminating and pressurizing rolls with thickness feedback improve active material bonding and electrode thickness consistency.
