What is the production process of a lithium-ion battery cell?

The ‘Production Process of a Lithium-Ion Battery Cell’ guide pro-vides a comprehensive overview of the production of different battery cell formats, from electrode manufacturing to cell assembly and cell finishing. Furthermore, current trends and innovation of different process technologies are also explained.

How are lithium-ion batteries made?

The manufacturing process of lithium-ion batteries consists largely of 4 big steps of electrode manufacturing, cell assembly, formation and pack production, in that order. Each step employs highly advanced technologies. Here is an image that shows how batteries are produced at a glance. ▶STEP 1.

What are lithium ion battery cells?

Manufacturing of Lithium-Ion Battery Cells LIBs are electrochemical cells that convert chemical energy into electrical energy (and vice versa). They consist of negative and positive electrodes (anode and cathode, respectively), both of which are surrounded by the electrolyte and separated by a permeable polyolefin membrane (separator).

How are batteries made?

In the cell assembly process, batteries take the shapes as we know them. The order of manufacturing process differs depending on the shape (cylindrical, pouch, and prismatic types) and each battery maker employs different technology. Pouch-type battery: First, a mono-cell is manufactured as the basic unit for battery production.

What are the challenges in industrial battery cell manufacturing?

Challenges in Industrial Battery Cell Manufacturing The basis for reducing scrap and, thus, lowering costs is mastering the process of cell production. The process of electrode production, including mixing, coating and calendering, belongs to the discipline of process engineering.

What materials are used in lithium-ion batteries?

A comprehensive review of separator membranes in lithium-ion batteries, 2023 As starting materials for the wet process, mixtures of HDPE (high-density polyethylene) or UHMWPE (ultra-high molecular weight polyethylene), mineral oils as plasticizers, and some additives are used.
