    Abstract: 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.

    Abstract translation: 锂蓄电池包括由集电器形成的叠层,包括凹陷区域,电极和用于形成电极的材料的多个膨胀腔。 每个膨胀腔包括由电极的一部分形成的至少一个壁。 优选地,电极是由至少一种能够插入和取代插入Li + +离子的材料形成的电极,当插入Li + +离子时,该材料的体积增加。 因此当将Li + +阳离子插入材料时,膨胀腔的空体积可以至少部分地被形成电极的材料的一部分填充。 膨胀腔形成在集电体的凹陷区域中。
