a terminal electrically connected to the electrode assembly; and a case accommodating the electrode assembly and the terminal, wherein the terminal includes a collecting plate connected to the electrode assembly; a collecting terminal connected to the collecting plate and protruding out of the case; a terminal plate outside of the case, the terminal plate including a terminal through hole at one side thereof and a reinforcement member recess at another side thereof, the collecting terminal passing through the terminal through hole, and a female screw thread being provided to the reinforcement member recess; and a reinforcement member in the reinforcement member recess. ## Claims ### Claim 1 A secondary battery, comprising: an electrode assembly; a terminal electrically connected to the electrode assembly; and a case accommodating the electrode assembly and the terminal, wherein the terminal includes: a collecting plate connected to the electrode assembly; a collecting terminal connected to the collecting plate and protruding out of the case; a terminal plate outside of the case and electrically connected to the collecting terminal, the terminal plate including a terminal fixation recess in an upper portion thereof and a rivet part formed by riveting an upper portion of the collecting terminal being fixedly hung on the terminal fixation recess, a terminal through hole at one side thereof and a reinforcement member recess at another side thereof, the collecting terminal passing through the terminal through hole, and a female screw thread being provided to the reinforcement member recess; and a reinforcement member in the reinforcement member recess. ### Claim 2 (depends on 1) The secondary battery as claimed in claim 1, wherein the reinforcement member includes a spring-shaped coil. ### Claim 3 (depends on 1) The secondary battery as claimed in claim 1, wherein the reinforcement member includes a threaded insert. ### Claim 4 (depends on 1) The secondary battery as claimed in claim 1, wherein the reinforcement member includes a hollowed part. ### Claim 5 (depends on 1) The secondary battery as claimed in claim 1, wherein the collecting terminal passes through the terminal plate and is riveted thereto. ### Claim 6 (depends on 1) The secondary battery as claimed in claim 1, further comprising an insulating lead coupled to an outer portion of the terminal plate. ### Claim 7 (depends on 1) The secondary battery as claimed in claim 1, wherein: the terminal plate includes: a terminal body in which the terminal through hole and the reinforcement member recess are disposed; the terminal fixation recess in an upper portion of the terminal body; and a terminal rotation prevention recess in a lower surface of the terminal body, and the terminal through hole and the reinforcement member recess are between upper and lower surfaces of the terminal body. ### Claim 8 (depends on 7) The secondary battery as claimed in claim 7, wherein the terminal plate further includes a terminal coupling recess in a lower periphery of the terminal body. ### Claim 9 (depends on 1) The secondary battery as claimed in claim 1, further comprising a cap assembly, the cap assembly including a cap plate sealing the case, wherein: the collecting terminal passes through the cap plate, and the terminal plate is outside of the cap plate. ### Claim 10 (depends on 9) The secondary battery as claimed in claim 9, wherein the cap assembly includes an upper insulation member between the terminal plate and the cap plate. ### Claim 11 (depends on 10) The secondary battery as claimed in claim 10, wherein the upper insulation member includes protrusions on upper and lower surfaces thereof. ### Claim 12 (depends on 11) The secondary battery as claimed in claim 11, wherein the cap plate includes a rotation prevention recess in an upper surface thereof, the rotation prevention recess corresponding to the protrusions on the lower surface of the upper insulation member. ### Claim 13 (depends on 11) The secondary battery as claimed in claim 11, wherein the terminal plate includes a terminal rotation prevention recess in a lower surface thereof, the terminal rotation prevention recess corresponding to the protrusions on the upper surface of the upper insulation member. ### Claim 14 (depends on 1) The secondary battery as claimed in claim 1, further comprising: a bus bar on an upper portion of the terminal plate; and a screw passing through the bus bar, the screw being coupled to the reinforcement member. ### Claim 15 (depends on 1) The secondary battery as claimed in claim 1, wherein the reinforcement member recess is spaced apart from the terminal hole. ### Claim 16 (depends on 15) The secondary battery as claimed in claim 15, wherein the terminal hole is closer to a center of the secondary battery than the reinforcement member recess. ### Claim 17 (depends on 1) The secondary battery as claimed in claim 1, wherein the reinforcement member recess is not concentric with the terminal hole.
