Abstract: An electrochemical cell including a container including an electrochemical spiral bundle including: a positive electrode including an active material selected from among SOCl2, SO2, SO2Cl; CFx where x≤1.5; MnO2, FeS2, V2O5, I2, Bi2O3, Bi2Pb2O5, CuCl2, CuF2, CuO, Cu4O(PO4)2, CuS, FeS, MoO3, Ni3S2, AgCl, Ag2CrO4, SVO, MO6S8, and a mixture of a plurality thereof; a separator; and a negative electrode including an active material made of lithium metal or of a lithium-based alloy. The outer face of the spiral, facing the container, is formed by the positive electrode, and a strip of lithium or of a lithium-based alloy at least partially covers the inner face of the container. The strip pressed against the inner face of the container makes it possible to make use of an outer face of the positive electrode which forms the last turn of the spirally-wound electrode plate group.
