Tesla batteries, also known as lithium-ion batteries, are a crucial component of electric vehicles like the Tesla Model S and Model 3. But how are these batteries made? Here is a step-by-step guide to the manufacturing process:
1) Raw Materials: The first step in making a Tesla battery is to obtain the raw materials that will be used. These materials include lithium, cobalt, and aluminum, as well as various other chemicals and compounds
2) Mixing and Blending Once the raw materials have been obtained, they are mixed together in a process called blending. This is typically done using large industrial mixers and involves combining the materials in precise ratios to ensure that the battery will have the desired properties.
3) Calendering: After the materials have been blended, they are pressed into thin sheets or strips using a process called calendering. This helps to create a uniform consistency in the battery material and ensures that it will perform consistently.
4) Punching and Cutting: The thin sheets of battery material are then cut into small pieces using a punch press or similar machine. These pieces will eventually become the individual cells that make up the battery.
5) Assembling the Cells: The small pieces of battery material are then assembled into cells, which are the basic building blocks of a battery. This typically involves adding a separator and electrodes to the cell, as well as encasing it in a protective casing.
Of course, a lot of testing is done to make sure the final battery meets all the saftely and standard requirements.
The battery space will only get better in terms of quality, power and how long they last.
