Abstract

Disclosed herein relates to a method of manufacturing a secondary battery including: stacking a plurality of unit cells in a first direction to form a stack-type electrode assembly; coupling a multifunctional terminal block (MTB) to both ends of the stack-type electrode assembly extending in a second direction perpendicular to the first direction; attaching a laminate sheet to the MTB to enclose the stack-type electrode assembly; injecting an electrolyte into the stack-type electrode assembly enclosed by the laminate sheet; and sealing the laminate sheet to form a cell case, wherein the MTB includes: a MTB housing; a busbar provided within the MTB housing and electrically connected to the stack-type electrode assembly; and an electrode terminal part exposed to an outside of the MTB housing and electrically connected to the busbar.
