A lithium storage battery comprises a stack formed by a current collector comprising recessed zones, an electrode and a plurality of expansion cavities for the material forming the electrode. Each expansion cavity comprises at least one wall formed by a part of the electrode. Preferably the electrode is an electrode formed by at least one material able to insert and de-insert Li+ ions, the volume of which material increases when Li+ ions are inserted. The empty volume of the expansion cavities can thus be at least partially filled by a part of the material forming the electrode when Li+ cations are inserted in the material. The expansion cavities are formed in the recessed zones of the current collector.
