China World Technology Battery Service Group Factory Tour

Battery production lines are critical for manufacturing various types of batteries, including lithium-ion (Li-ion) and lead-acid batteries. These lines are designed to ensure high efficiency, safety, and quality while minimizing environmental impact. Below is an overview of key processes, technologies, and equipment used in modern battery production.

eg. Lithium-Ion Battery Production Line

Lithium-ion batteries are produced through a three-stage process: preliminary processing, cell assembly, and post-processing.

Preliminary Processing (Front-end):

Material Mixing: Solid battery materials (cathode, anode, etc.) are mixed with solvents to form a slurry using vacuum mixers .

OEM (Original Equipment Manufacturer)

Definition: OEM stands for Original Equipment Manufacturer, commonly referred to as "contract manufacturing" or "brand licensing." In this model, a battery company designs the product but outsources the manufacturing to another company. The final product carries the brand of the original company.
Key Features:

• The battery company retains design and intellectual property (IP) rights.

• The manufacturing partner focuses solely on production, adhering to the brand’s specifications.

• Common in industries where brand value outweighs manufacturing control (e.g., premium battery brands).
Example: A battery company like Panasonic designs lithium-ion batteries for Tesla, who then produces and sells them under the Tesla brand.

ODM (Original Design Manufacturer)

Definition: ODM stands for Original Design Manufacturer, also known as "white-labeling." A battery company designs and manufactures a product, which can then be rebranded and sold by another company.
Key Features:

• The battery company owns both the design and production capabilities.

• Clients can choose to use the design as-is or modify it slightly.

• Profit margins are higher than OEM due to added value from design expertise.
Example: A battery manufacturer like CATL (Contemporary Amperex Technology) designs a high-density battery pack and sells it to smartphone brands like Xiaomi or Apple, who brand it under their own names.
