Rotationally symmetrical sub-modules simplify high-cell-count battery assembly, cutting build time and weight while preserving stable connections.
Varying active material layer thickness across stacked electrodes helps balance battery energy density, output performance, and current flow.
Alternating adhesive coating weights and cut placement suppress separator peeling and curling in secondary battery laminates.
Pre-formed bus bar holes let straight battery tabs be inserted and welded, cutting bending steps, assembly cost, and tab deformation.
Protruding separators are heat-bonded and folded back to hold cell alignment, prevent shorts, and limit assembly width.
Segmented resin sealing members and spacers absorb detection-line thickness while limiting current collector deformation and sealing defects.
A joined resin seal and welded laminate structure stabilizes communication-hole sealing while allowing electrolyte filling without leakage.
Selective resin removal exposes facing metal layers at tab regions, enabling low-resistance energization and secure lead fixation in battery electrodes.
A top cover protrusion blocks weld laser leakage and falling particles from reaching the electrode assembly inside the battery cell.
Thermally conductive brackets and insulation pads cool tightly stacked pouch cells while improving protection and avoiding coolant leakage.
A molded separator protrusion balances drop resistance and electrolyte impregnation in a wound battery while reducing leakage risk.
A recessed packaging bag creates concave space for tabs and conductive parts, raising battery cell energy density while limiting contact and leakage risk.
Inward-pinched case walls restrain electrode movement while preserving expansion space and gaps for electrolyte entry and gas escape.
An elastic concave-convex retainer fills case gaps to ease electrode insertion while preventing assembly movement and damage.
An insulating coating on the adjacent electrode slit surface blocks tab-end short circuits while preserving stack shape and simpler processing.
