摘要: Die Erfindung betrifft ein Verfahren zur Fertigung einer Lithiumionen-Batteriezelle, insbesondere Batteriepouchzelle, mit einem Formationsprozess, in dem die Batteriezelle einem Erstladevorgang unterworfen wird, in dem sich Lithiumionen in Aktivmaterial (3, 5) der zumindest einen Anode (A) der Batteriezelle einlagern, und zwar unter Bildung einer SEI-Grenzschicht (9) an der Grenzfläche zum Elektrolyt (E) sowie unter Gasbildung (12), wobei beim Erstladevorgang die Batteriezelle in einen Ladestromkreis (LK) geschaltet ist und mit Gleichstrom geladen wird. Erfindungsgemäß ist der Erstladevorgang in einzelne Ladephasen (L) unterteilt, in denen sich jeweils eine SEI-Teilschicht (10) mit feinkörnigem Gefüge ausbildet. Die einzelnen Ladephasen (L) sind von Nichtladephasen (N) unterbrochen, in denen keine SEI-Bildung erfolgt, so dass die nach dem Erstladevorgang gebildete SEI-Grenzschicht (9) aus den übereinandergeschichteten SEI-Teilschichten (10) aus feinkörnigem Gefüge besteht, das eine Lithiumionen-Mobilität in der SEI-Grenzschicht (9) unterstützt.

摘要: The present invention relates to a discharge method of a battery, comprising: a first discharging step of discharging a battery by connecting the battery and a power converter and applying voltage thereto; and a second discharging step of discharging the battery by applying a reverse voltage of the voltage of the first discharging step, after the first discharging step. According to the present invention, electrical energy of a battery can be recovered and recycled, and an electrically safe state can be secured in a subsequent disassembly process by putting the battery in a completely discharged state in which normal operation is impossible.

摘要: Processes for discharging of batteries, battery cells and modules are provided, including processes for deep discharging of rechargeable battery cells having electric poles with contactors, said battery cells being present in one or more battery packs in a battery system managed by a battery management system (BMS), the processes comprising connecting the battery system to a power source;
activating a recycling mode in the BMS of the battery system, wherein the recycling mode allows the battery cells of the battery system to be discharged below undervoltage limits; and discharging the battery cells of the battery system. A battery system for performing the processes is also provided.-
