The Cell Assembly & Sealing System

The Future of Cell Assembly

The Cell Assembly & Sealing System is a fully automated, benchtop machine that builds single-layer cells with speed and precision. Designed to fit through the antechamber of a two-glove glovebox, this system makes it easier than ever for research and quality assurance labs to test cells of the highest standard.

System Features & Specifications

Straight to Scale-Up

The Cell Assembly & Sealing (CAS) System is designed to build both coin cells and single-layer pouch cells. This allows for a seamless transition from basic research to commercially-relevant testing, all with a single machine. New operators can easily switch between these two cell formats in under 5 minutes, without requiring any additional tools.

Save Time with Automatic Loading

Reduce the time spent building coin cells up to 95% using the Autoloader, our automatic sample loading module. Scalable to build over 100 cells per operation, completely unattended.

Lower the skill barrier to cell assembly

Save on training and recruitment costs by enabling everyone on your team to build cells of a consistent, high quality. The Cell Assembly & Sealing System is intuitive and easy to use, making sure data quality is never limited by cell quality.

Automated Quality Control

Add another dimension to your data analysis using our integrated machine vision system. Record the electrode alignment and coating quality of every cell made.

Flexible Electrochemical Exploration

Build coin cells and pouch cells with the CAS System in either full-cell or half-cell configuration. Add a reference electrode and control electrode stack pressure using our next generation proto-cell format.

FAQs

The Cell Assembly and Sealing System (CASS) can make any size coin cell. It can also make single-layer pouch cells with up to 40 x 60 mm electrodes, including custom geometries. The CASS cannot produce multilayer cells as there are no in-built tab welding capabilities, so tabs must be welded onto electrodes before placing them in the system.

A proto-cell is essentially a coin cell in a pouch casing. This format enables users to control the pressure more precisely, and add a reference electrode (third electrode) to see how the voltage of each electrode changes individually while charging and discharging.

The throughput of the CAS System depends on the build configuration, but on average, it is 2.5 to 5.0 minutes per cell, so 12 to 24 cells can be built per hour.

Yes, Cellerate systems are designed with glovebox work in mind so they can be used with the battery industry’s most challenging materials. This includes considerations for electronics operating under an argon atmosphere and in a vacuum.

Yes, there is an API for the Cellerate system, which uses Python. This makes integrating the system with LIMS (Laboratory Information Management System) easy.

Not at the moment, but we are in the process of developing an app – so watch this space.
No, all that is needed to operate the CAS System is a connection to standard mains electricity. For glovebox use, we have designed the power cable to pass through a KF-40 port.
