  "textContent": "A battery cell includes a case provided with an accommodation space; and an electrode assembly accommodated in the accommodation space and contacting the case. The electrode assembly includes a negative electrode including a plurality of negative electrode current collectors, on which a negative electrode mixture is coated, and a deformation absorbing member interposed between the plurality of negative electrode current collectors; a positive electrode including a positive electrode current collector on which a positive electrode mixture is coated; and a separator interposed between the negative electrode mixture and the positive electrode mixture. The deformation absorbing member may be interposed between surfaces, opposing a surface on which the negative electrode mixture is coated, of the negative electrode current collector and may be pressurized or stretched by at least one of the negative electrode and the positive electrode to contract or expand.",
