Electrode Rolling/Calendering TRIZ Cases

Blank regions on anilox roller bosses prevent slurry bonding, reducing substrate wrap angle fluctuations and improving coating consistency.

Segmented mesh openings confine lithium growth to prevent dendrite formation while maintaining high capacity retention rates.

Creating a mixed phase at the interface between the high-resistance layer and active material prevents delamination during battery manufacturing.

Composite particles with sulfonic acid polymers resolve slurry viscosity trade-offs, ensuring uniform film thickness and high initial capacity.

Pre-assembly electrolyte coating forms a stable passive film on lithium metal electrodes to enable uniform surface deposition.

A pre-lithiated precursor electrode uses a lithium foil layer to form a lithium reservoir during cell assembly.

Stabilized lithium metal powder coating compensates for irreversible capacity loss during first cycle SEI formation, improving coulombic efficiency.

Pretreating lithium battery electrodes with specific electrolyte compositions forms a stable solid electrolyte interphase film before assembly.

Encapsulated sulfur particles in a high-density slurry boost conductivity while controlling polysulfide diffusion to improve cycle life.

Pre-integrated fluid channels in battery electrodes eliminate vacuum filling steps, enabling rapid and uniform electrolyte distribution.

A patterned non-coating portion on an electrode foil modifies local material properties to match coating ductility during manufacturing.

Partial sealing near terminals prevents electrolyte leakage during injection, ensuring reliable battery assembly.

A melting induction solvent vaporizes to create a humidified space for uniform separator surface melting during electrode lamination.
