Original Abstract Submitted

In the energy storage cell according to the present disclosure, the first wound electrode assembly includes a first positive electrode and a first negative electrode. The second wound electrode assembly includes a second positive electrode and a second negative electrode. The second positive electrode is not in contact with the first positive electrode. The second negative electrode is not in contact with the first negative electrode. The second wound electrode assembly is formed by winding around the first wound electrode assembly on the outer peripheral side of the first wound electrode assembly. The positive electrode current collector member is electrically connected to both the first positive electrode and the second positive electrode. The negative electrode current collector member is electrically connected to both the first negative electrode and the second negative electrode.
