CASS
Precision Robotic Assembly for High-Quality Battery Cell Data
The CASS is an automated platform designed to assemble and seal coin cells and single-layer pouch cells with exceptional consistency. By replacing manual assembly with precision robotics, the CASS enables laboratories to improve repeatability, reduce human variability, and increase throughput. Designed specifically for battery research environments, the CASS supports structured workflows that produce reliable, comparable cell data at scale.
Machine Vision Electrode Alignment
The system uses a patented, high-definition vision processing unit to ensure each electrode is correctly aligned before sealing. The high-definition cameras log the build of every cell for quality control.

Convert Untrained Technicians Into Battery Experts Overnight
With the CASS, it only takes 2 weeks to convert your new, untrained technicians into proficient battery production and testing operators. With new users achieving 75%+ success rates in just two days.
Suitable for all Types of Cells
The system works with an interchangeable coin and pouch dies designed to accommodate a range of shapes and sizes, depending on your requirements. Cellerate has developed a new test cell format called the Protocell. It is a novel approach to cell development that uses standard coin cell-sized electrodes but in a pouch cell format.

Module Configurations
Designed for ease of scalability, the modular approach allows the system to scale with the laboratory requirements.
From individual cell builds to fully automatic batch production.
CASS: Sealer + Assembler
The first step into automated cell assembly, the Sealer and Assembler combination allows for precision cell assembly of coin cells using active optical alignment and precise stage control.
- Patented optical alignment system allowing for less than 100um electrode overlay error
- Flexible electrolyte dispensing using an electronic micropipette
- Vision logging and traceability of every build step

CASS: Sealer + Assembler + Autoloader
The addition of the Autoloader module allows you to significantly scale production, unlocking the capability to reliably produce up to 100 prototype cells, completely unattended.
- Reduce the time spent building coin cells up to 95%
- Total setup time of around 1 hour for 100 cells
- Scale up your automated cell assembly processes
CASS: IQ
Designed for large-scale testing environments, the CASS-IQ extends the capabilities of the CASS platform to enable fully automated, high-throughput cell production. Built for quality control and materials validation programs.
- Fully automated workflow from electrode rolls to completed cells
- High-throughput production of 100–500 coin cells or Protocells per day
- Integrated in-line OCV measurement for automatic quality verification of each cell

Sealer Module
The Sealer module allows for the crimping of coin cells, vacuum sealing of Protocells and single-layer pouch cells. The rapid exchange of the sealing dies allows for the multifunctionality in a small footprint.
- Can seal coin cells and pouch cells
- Pouch cell vacuum sealing using integrated vacuum pump
- Rapid die exchange for sealing different cell types
- Fully digital interface and control systems
- Can be used as a standalone system
Specifications
Assembler Module
The Assembler module uses machine vision to accurately stack cell components. Assemble cells with precision, in fully or semi-automated modes.
- Assemble both coin cells and Protocells
- Less than 0.1 mm component misalignment
- Automatic swapping between vacuum heads and micropipette tips to minimise cross-contamination
- Cell build quality report automatically generated
Specifications
Autoloader Module
The Autoloader module enables 100 cells to be built unattended as standard, and can be expanded to build more.
- Make every cell unique to explore parameter space
- Create, save, and load cell build routines for batch cell building
- Build 100 cells automatically using tray loading mechanism
- Set-up time approximately 1 minute per cell
- Compatible with both coin cells and Protocells

FAQs
What cell formats and cell sizes can the CASS make?
The CASS can make any size coin cell. It can also make single-layer pouch cells with up to 50 x 70 mm electrodes, including custom geometries.
What is a Protocell?
A Protocell 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. Find out more about Protocells.
What is the throughput of the CASS?
The throughput of the CASS depends on the build configuration, but on average, it is 2.5 to 5 minutes per cell, so 12 to 24 cells can be built per hour.
Can the output data be accessed remotely?
Yes, the system can be accessed remotely over the local network, and a third party LIMS can pull the data through a Python script.
What external services does the CASS require?
The CASS only requires a 'standard' 110-240V mains power source. No compressed air or external vacuum pump is required. The CASS can also connect to a local network via wifi or ethernet.
