Small-Sized Cells Cases/Jackets TRIZ Cases

Relocating the fixing portion to a second surface opposite the electrode terminal creates working space for connection operations, improving productivity.

Spring-biased movable electrical contacts disconnect upon transverse movement, preventing high-voltage short circuits during vehicle collisions.

A battery sensor positioner secures the sensor casing to prevent rotation during tightening.

A movement restricting member constrains current collector motion within an electrochemical device to prevent internal short-circuits.

A non-aqueous electrolyte secondary battery uses 1-propene 1,3-sultone to maintain electrical contact between the exterior can and negative electrode core.

Variable rib thickness eases coupling boss insertion while root rigidity maintains structural strength.

A connecting member with a thinned intervening portion joins battery terminals via welding, suppressing heat propagation to the cell.

Segmented terminal flanges with internal material boundaries improve connection reliability by isolating weld zones from electrode interfaces.

Curved polymer gasket eliminates gaps between cap assembly and case, preventing electrolyte leakage under high temperature conditions.

Strategic connecting surfaces enable precise laser beam welding of battery cell housings, resolving positioning complexity while ensuring a tight seal.

Lead frame package integrates protection IC, dual FET chip, and passive devices to reduce circuit board area while minimizing manufacturing processes.

Insulating holder with rib coupling spaces batteries within a metal thermal conductor, resolving mechanical stability versus heat dissipation trade-offs.

Phosphorus-containing flame retardants in polycarbonate resins maintain impact resistance while achieving high flame retardancy.
