3 Facts About The Cell Manufacturing Process For Lithium Batteries

by Eva Gilbert

Batteries have become an integral part of many consumer products. The right batteries can make certain products mobile, which increases their usefulness and value.

Advancements in technology have led to the development of a wide range of battery technologies. Of these technologies, many would agree that lithium batteries represent the battery of the future.

Learn more about the cell manufacturing process used in the production of lithium batteries so you will be prepared to appreciate these power sources in the future.

1. All Cells Contain Three Components

Each individual cell within a lithium battery is actually a combination of three very important components. These components are the anode, cathode, and electrolyte.

Lithium batteries produce power when electrons move from the anode to the cathode through the electrolyte. Without these three vital components, lithium batteries would be unable to produce the type of energy needed to efficiently power today's consumer devices.

2, Anodes and Cathodes are Manufactured Separately

It is absolutely essential that the anodes and cathodes used in lithium battery cell manufacturing are produced separately to avoid any potential cross-contamination.

Both the anodes and cathodes are mixed with a conductive binder on separate production lines to form a slurry. The anodes are then covered in aluminum foil, while the cathodes are covered in copper.

Both components are then sent to a specialized oven that bakes these foils onto the individual components.

Once the anodes and cathodes have sufficiently cooled, they are wound together to create terminals for a lithium battery.

3. Electrolyte is Added Last

The addition of the electrolyte is the final step in lithium battery cell manufacturing. All electrolytes must be added to the developing cell using vacuum technology.

This is due to the fact that any exposure to oxygen could cause the electrolyte to undergo a chemical reaction that would reduce its ability to act as an efficient transmitter for electrons.

Manufacturers will often include safety features, like vents, in the design of their lithium battery cells to help dispel heat and ensure the electrolyte remains as stable as possible.

Cell manufacturing is the first step in the creation of a lithium battery. Multiple cells are welded to a plate on both the anode and cathode sides and assembled into packs. These packs can be combined with one another to form a wide range of amp-hours.

The intended purpose of the lithium battery will determine how many cell packs must be formed together during manufacturing.
