Large-Sized Flat Cells/Batteries TRIZ Cases
- Bipolar Battery Liquid Gasket Sealing Against Electrolyte Infiltration
A liquid gasket seals the positive electrode interface and communication holes to block sulfuric acid ingress and limit battery deterioration.
- Bipolar Battery Plate Via Connection for Corrosion Resistance
A via-linked collector connection with sealant layers blocks electrolyte contact, reducing corrosion and extending bipolar battery plate life.
- Bipolar Electrode Through-Hole Structure to Block Adhesive Contamination
A projecting conductor around the through-hole bonding area redirects adhesive, preserving conduction area and lowering resistance in bipolar lead-acid batteries.
- Electrode Plate Tab Structure for Lower Resistance in Secondary Batteries
A two-region non-coated tab structure cuts spreading resistance and heat generation, improving charge-discharge efficiency and battery life.
- Battery Module End Plate With Integrated Lug for Simpler Pack Assembly
An end plate with an integrated lug replaces a separate connecting beam, cutting battery pack parts, assembly steps, and stress-related failure risk.
- Electrode Plate Tab Layout for Lower Non-Coated Resistance
A two-region non-coated tab layout lowers spreading and constriction resistance, cutting heat generation and improving battery charge-discharge life.
- Long-Width Secondary Battery Electrode Assembly for Lower Resistance
Cross-connected conductive members between uncoated current collector portions shorten current paths in long-width secondary batteries and reduce resistance.
- Secondary Battery Current Interruption Structure for Vibration Reliability
Fixing and displacement-prevention projections stabilize the current collector and enable reliable pressure-triggered current interruption under impact.
- Pouch Battery Cell Layout for Higher Module Space Utilization
A unidirectional pouch cell with case protrusions and integrated busbar framing cuts dead space, simplifies assembly, and improves cooling.
- Integrated Electrode Tab Bundle With Melted Through-Hole Connector
A low-melting connector inserted through tab-bundle holes avoids welding impurities and enables thermal separation to reduce battery explosion risk.
- Negative Electrode Taper Density Layout to Prevent Lithium Deposition
A tapered, lower-density negative electrode edge improves Li-ion cell energy density while suppressing lithium deposition and short-circuit risk.
- Metal-Hydrogen Electrode Stack Assembly for Reliable Grid Storage
Alternating electrode stacks with joined anode and cathode buses improve metal-hydrogen battery reliability for large-scale energy storage.
- Battery Cell Electrode Tab Structure for Low-Strain Laser Welding
Burring-processed electrode tabs improve laser welding to current collectors, limiting clearance and thermal strain while maintaining secure bonding.
- Battery Terminal Rivet Structure for Gap-Free Current Collector Joining
A spot-faced hole with a bottom protrusion and edge welding suppresses terminal-to-collector gaps and improves battery connection reliability.
- Linked Battery Module Assembly for Lighter Pack Housing
A linking unit joins battery modules so packs need less housing rigidity, cutting assembly work, size, and weight while protecting cables.
