How Accurate is Top 20 Lithium Ion Battery Manufacturers Table?
The gigafactory announcements are constantly flowing, and so the total is varying constantly.
The IRA act has delivered a tsunami of gigafactories announcements. New factory capacity exceeds 3TW. Add to this list flow batteries and other battery technologies of over 100 GW per annum.
Tesla alone has stated its target is over 1,000 GW within 4 years.
Battery Physical Shapes
- Cylindrical: 18650, 26650, etc., with thin metal casing.
- Button or coin cells: most are not rechargeable, but we make coin cells to test rechargeable chemistries.
- Prismatic:
- Type-1 is a roll of electrodes flattened to fit inside a rectangular metal can
- Type-2 is a stack of pouch cells inside a rectangular can.
- Pouch cells: same as everything above, but flat and in a flat bag made of a laminated polymer film with aluminum foil.
Cell Batteries
Pouch Batteries
CATL and many others have focused on pouch batteries
