Coin Cell Assembly Line For Lab Research

Lab Button battery assembly machine, also known as coin cell equipment, is used to make a battery whose overall dimension is like a small button. Generally speaking, the battery has a large diameter and a thin thickness. Button batteries are classified according to their appearance. The same corresponding batteries are classified as cylindrical batteries, pouch batteries and prismatic batteries.

In coin cell pilot line, lithium ion button battery is mainly composed of the following parts: positive case, negative case, (positive/negative) electrode sheet, separator, spacer, spring and electrolyte.

The battery case of the commonly used button type battery is CR2032, CR2025, CR2016, etc., C represents the coin cell system, and R represents the battery shape is circular. The first two digits refer to the diameter (unit: mm) and the last two digits refer to the thickness (unit: 0.1mm), whichever is closer. For example, the approximate size of CR2032 is 20mm in diameter and 3.2mm in thickness.

Coin cell assembly plant includes: mixing electrode slurry, coating, drying, rolling press, disc punching, electrolyte injection, crimping... ...
