Abstract
A method for producing a lithium-ion cell is provided. The electrochemically active coating of an electrode is brought into contact with an electrolyte or an auxiliary liquid before a winding or cutting operation. This method is suitable in particular for continuously producing lithium-ion cells by means of processes proceeding at high speed, such as winding processes.
Claims19
A method for producing a lithium-ion cell, comprising the following steps:
- A) providing a first electrode having a first electrode collector and a first electrochemically active coating applied onto the first electrode collector, and a second electrode having a second electrode collector and a second electrochemically active coating applied onto the second electrode collector,
- B) contacting at least part of the first and/or second electrochemically active coating with an electrolyte,
- C) cutting, winding and/or folding the first and/or second electrode, wherein step C) is carried out after step B), and
- D) combining the first electrode with a separator and the second electrode.
