How are lithium ion batteries processed?

Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.

What are the production steps in lithium-ion battery cell manufacturing?

How are lithium ion battery cells manufactured?

The manufacture of the lithium-ion battery cell comprises the three main process steps of electrode manufacturing, cell assembly and cell finishing. The electrode manufacturing and cell finishing process steps are largely independent of the cell type, while cell assembly distinguishes between pouch and cylindrical cells as well as prismatic cells.

What is the construction of a lithium ion battery?

The construction of a lithium ion battery is one of the most important aspects that determine its performance and lifespan. Essentially, a lithium ion battery consists of several components including electrodes, electrolyte, separator and casing. The two electrodes used in lithium-ion batteries are typically made from metal oxide or graphite.

Why is cell formation important in lithium ion battery production?

(2021), p. 100090, 10.Abstract. The battery cell formation is one of the most critical process steps in lithium-ion battery (LIB) cell production, because it affects the key battery performance metrics, e.g. rate capabi ity, lifetime and safety, is time .

Are competencies transferable from the production of lithium-ion battery cells?

In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs.
