This abstract first appeared for US patent application 20250070421 titled 'OUTER TERMINAL CONNECTION STRUCTURE OF SECONDARY BATTERY
Original Abstract Submitted
an outer terminal connection structure of a secondary battery, includes: a first current collector to be welded to non-coating portion tabs of an electrode assembly; a second current collector electrically connected to the first current collector; a cap plate above the second current collector, and connected to an opening of a case, the cap plate having a plate hole; an outer terminal above the cap plate, and electrically connected to the second current collector; an insulator passing through the cap plate to be located above and below the cap plate, the insulator to support the outer terminal at an upper side, and contact the second current collector at a lower side; and a terminal connection part passing through the plate hole to electrically connect the second current collector to the outer terminal. the outer terminal connection structure includes a rotation prevention structure to restrict a relative rotation.
