  "textContent": "A cylindrical battery includes a battery housing accommodating an electrode assembly having a first electrode, a second electrode, and a separator spirally wound about a central axis in a core of the electrode assembly such that the first and second electrodes each have an inner end and an outer end. A stress vulnerable sector is defined by an arc of an outer circumference of the electrode assembly between a first radius and a second radius extending from the central axis through the inner end of the first electrode and the second electrode, respectively. A stress amplification sector is defined by an arc of the outer circumference between a third radius and a fourth radius extending from the central axis through the outer end of the first electrode and the second electrode, respectively. At least the outer end of the first electrode is not positioned within the stress vulnerable sector.",
