Large-Sized Flat Cells/Batteries TRIZ Cases

Compressing and heating an electrode stack creates a compact battery cell with better heat dissipation, stability, and scalable production.

By replacing notching with display-guided cutting on bonded non-coating portions, this case reduces burrs, delamination, and tab-forming time.

A flexible support film and support plate replace metal busbar holders, improving welding tolerance, assembly productivity, and module weight.

Localized support areas in a prismatic cell housing maintain edge contact pressure, lowering resistance and preventing lithium metal formation.

Compression-connected single-stack pouches isolate electrolyte and defects while avoiding welding metal contamination in battery manufacturing.

A flexible support film and support plate replace metal busbar holders to cut module cost, improve assembly yield, and reduce welding failures.

Seal coatings around current collector edges block lithium plating from torn anode tabs while preserving electrolyte and reducing short risk.

An elastic interlayer and grooved anode regions absorb expansion mismatch in bipolar electrodes, suppressing warping during charge and discharge.

Multiple electrode assemblies and current collecting plates improve weldability, prevent electrode cracks, and raise battery capacity density.

Grooved insulating members expand tab-to-collector contact area, stabilizing battery cell connections while removing a separate insulator step.

An offset current collector foil layout helps laminated batteries avoid high-heat external short circuits under orthogonal loading.

Deformable housing sections absorb battery cell expansion, reducing pressure, stress, and deterioration while preserving module stability.

Grooved insulation integrated with the current collector enlarges tab contact area, stabilizing battery cell connections and simplifying assembly.

An insulating spacer in a bipolar battery laminate increases foil-to-electrode distance to prevent short-circuiting under external force.

A larger separator projects beyond carrier foil edges to prevent warping and short circuits, enabling faster bipolar battery stack assembly.

Independent drive cells in one housing deliver selectable power levels while simplifying battery module assembly, cost, and reliability.

Deformable housing sections absorb battery cell expansion stress, helping preserve module durability and safety during charging and heat exposure.

Local deformation of can faces evens stack pressure in electrochemical cells, reducing lifespan variation and performance anomalies.

Shared current collectors and freestanding sulfide electrolyte layers enable bipolar solid-state batteries with high conductivity and thermal stability.

A segmented module frame separates the electrolyte injection port from stacking protrusions and recesses to prevent module misalignment.

Matrix unit electrodes track leakage current by coordinates to quickly locate foreign material in low-voltage battery cells without destructive testing.

A nested packaging film and metal shell use pressure differentials to limit core movement, improve sealing, and reduce electrolyte leakage.
