Successful Acceptance of New Energy Laboratory Equipment for Coin Cell Batteries

On July 8, Xiamen TOB New Energy Technology Co., Ltd. welcomed another group of customers for equipment acceptance. The newly accepted equipment is dedicated to laboratory research on lithium-ion coin cell batteries, including glove boxes, punching machines, and crimping machines. This acceptance process, led by Ailsa Zheng, Head of Sales Team 3, with full technical support, concluded with unanimous confirmation that the equipment met requirements through on-site operation and data testing.

1. High-Purity Glove Box: Creating a "Water-Oxygen-Free" Microenvironment

Core materials for coin cell batteries (e.g., electrolytes, electrode active materials) are highly sensitive to water and oxygen—trace impurities can lead to capacity decay, shortened cycle life, or even battery failure. Therefore, laboratory-grade glove boxes must control water and oxygen content inside the box below ppm (parts per million) levels. These boxes support full-process operations, including electrode sheet preparation, battery assembly, and vacuum electrolyte injection. Equipped with visual observation windows and anti-static operating gloves, they further ensure the accuracy and safety of R&D personnel’s operations.

2. Electric Sealing Machine

Powered by electricity, this machine TOB-DF-160 saves operational effort and can be configured with different molds for tasks such as dry powder pressing, wet powder pressing, molding, and riveting.
Mold Configuration: Standard molds are designed for 20-series coin cell batteries. By replacing mold accessories, it can also seal other coin cell batteries (e.g., 2450, 2430) and accommodate mold removal.

3. High-Precision Electrode Sheet Punching Machine: Ensuring "Thin yet Standard" Electrodes

Electrode sheets for coin cell batteries typically measure only 0.01–0.03 mm in thickness (about 1/5 the diameter of a human hair). Their thickness consistency and burr control directly impact battery internal resistance and energy density. Traditional punching machines often suffer from issues like edge burrs and large thickness deviations, leading to increased self-discharge rates. This machine TOB-CP60 features an upper punch die guided by high-precision rails, enabling high punching accuracy with no burrs, edge defects, or pressure marks. It can punch various battery materials with thicknesses ranging from 0.005 to 0.5 mm.
