  "textContent": "A secondary battery according to an embodiment of the present disclosure includes: an electrode assembly having a positive electrode plate and a negative electrode plate; a case for accommodating the electrode assembly and having one side open; a pair of current collector plates electrically connected to the electrode assembly and the case, respectively; and a cap assembly including a cap plate that seals the case and has an injection hole formed therethrough and an injection plug that seals the injection hole from the inside of the case. According to an embodiment of the present disclosure, an electrolyte injection structure may be improved, and thus process efficiency may be improved. In addition, since both the positive electrode and the negative electrode are formed in one direction of the secondary battery, a connection structure with an external terminal may be simplified.",
