Primary Cells TRIZ Cases

A phase-converted carbon slurry on carbon fiber cloth replaces metal electrodes to resist aqueous-electrolyte corrosion while preserving conductivity.

A zinc salt, organic additive, and formula (I) reshape Zn2+ solvation to curb dendrites while preserving Zn-MnO2 battery capacity and cycling.

Controlling LiX crystallites to 60 nm or less boosts argyrodite solid electrolyte conductivity while limiting phase instability.

By welding both tabs on the top cover assembly before housing insertion, this case reduces tab length, avoids housing interference, and simplifies sealing.

An integrated pressing step forms the terrace step and receiving portion together, preventing pouch fold dents and wrinkles while simplifying battery case manufacturing.

A local high-concentration phosphate electrolyte suppresses lithium dendrites, improves anode compatibility, and adds flame retardancy.

A stepped adhesive layer at the battery tab increases sealing area and peeling force, reducing leakage risk and improving pouch-cell life.

Integrated die cavities and inclined surfaces form a pouch battery terrace step without fold dents or wrinkles, keeping thickness low.

A dual-melting-point adhesive-sealant lets battery tab seals vent heat-driven gas while preserving insulation and structural sealing.

Reinforced battery housing flanges reduce welding deformation, improve connection strength, and preserve structural integrity during assembly.

Opposed offset fixing portions in a two-piece battery terminal reduce joint stress from heat and vibration during assembly and vehicle use.

A 3 mol/L or higher magnesium salt ether electrolyte suppresses sulfur diffusion and corrosion, improving magnesium-sulfur battery cycling.

Spaced bonding portions between the package and electrode assembly disperse shear stress to prevent aluminum foil tearing during drops.

A benzene-based compound with 1,3-dioxolane suppresses lithium polysulfide leaching, helping lithium-sulfur batteries retain capacity and cycle life.

Controlled spacing between the fill port and tab improves electrolyte diffusion while preventing spray onto tabs during battery filling.

Manganese or niobium doping lowers the sintering temperature of lanthanum-strontium titanate, enabling co-firing with yttria-stabilized zirconia electrolytes.

A dedicated groove in the battery case intercepts molten metal from circumferential welding, preventing short circuits and maintaining sealing reliability.

Integrated micro fuel cells use a three-dimensional fuel interchange on a flexible substrate to boost power density.

Introducing a secondary lithium compound into the host lattice creates a solid solution that boosts discharge capacity while maintaining thermal stability.
