EV Battery Manufacturing Process

Recent studies have estimated that the worldwide electric vehicle charger market is worth USD 7.01 billion and is expected to grow significantly— up to an astonishing USD 64.67 billion—by 2030. This tremendous growth can be attributed in part to the rising demand for EVs and increased focus on manufacturing quality EV batteries.

The main difference between an internal combustion engine (ICE) vehicle and an electric vehicle (EV) is what they use for propulsion. ICE vehicles use a petrol or diesel powered IC engine while an EV uses a battery. ICE vehicles also use a battery, a 12-V lead-acid battery to start. EVs rely on 400-V lithium-ion batteries for continuous operation.

In this era of electric mobility, the EV battery manufacturing process is a key factor in defining success or failure. It requires close attention to detail and precision if one wishes to ensure that the battery meets desired performance standards. So, how do automation manufacturers create an effective EV battery?

The process typically involves three steps: electrode manufacture, cell assembly, and conditioning.

Electrode manufacture

Two production lines are created—one for the anode and another for the cathode. A slurry is made to coat both sides of a foil. The foil is then dried in an oven. After this comes calendaring, as the coated foil is run through two heated rollers. Next, the foil goes through a slitting operation to create several coated coils.

Cell assembly

Cell assembly begins with cutting electrodes and inserting them into their respective containers: pouch cells, prismatic cells, or cylindrical cans. Coils are cut via laser, or mechanical techniques to obtain individual sheets, which are then stacked—anode/separator/cathode—and welded onto the main terminals. Finally, a fully-assembled cell is filled with electrolytes and sealed within its container before being ready for use.

Conditioning

Finally, the cells are put through rigorous charging and testing before being assembled into modules, subsequently combined together to form a pack, and then installed into the vehicle.

Now that you know the process behind creating an EV battery, it's easier to understand why quality and safety are paramount in manufacturing. Automation manufacturers must ensure that their products meet specific performance, durability, and longevity standards. With proper attention paid to each step of the production process, the resulting product will more than provide users with a smooth and trouble-free experience – it will delight them.
