State-of-the-art Cell Teardown Techniques

Our precise methods enable the safe opening of battery cells and their disassembly into individual components to assist you with troubleshooting, conducting aging analyses, or optimizing cell designs.

Precise
Quick Diagnostics

The perfect solution for you when you need to act quickly - for example in task forces.
Take advantage of our precise rapid diagnostics to speed up fault analysis following anomalies detected in cell tests or during battery operation.

We are happy to use diagnostic results, to optimize your aging and lifetime models, as needed.

Comprehensive Post-Mortem Analysis

Using state-of-the-art equipment, we and our partners help you analyze cell components and thereby determine the causes of performance degradation or failures.
Take advantage of our wide range of analytical methods to enhance the safety and longevity of your battery cells.

Why it's worth it to use BatteryQuest for your cell teardowns and post-mortem analyses.

Qualification

Cell teardowns and post-mortem analyses are performed by our experts, who have many years of experience working with cells.

We are one of the few providers in Germany that open charged NMC cells for you under strict safety protocols.

Speed

We handle the dangerous goods transportation ourselves. Within a few days, we’ll pick up your battery cells and transport them to our laboratories.

If we're already testing your battery cells, the process is even faster if any issues are detected. We offer you all relevant services under one roof.

Precision & Thoroughness

With many years of experience in battery cell development, we take a particularly precise and careful approach to cell disassembly. We take great care to ensure that our disassembly methods do not alter the condition of the cell components.

Once we have completed our teardowns and analyses, you will receive comprehensive, structured, and transparent reports.

Our Cell Teardown Approach

Learn, step by step, how our experts perform cell opening and analysis to enable accurate diagnoses.

Step One: Cell Preparation

We begin with carefully preparing the battery cell and documenting its characteristics. This includes, among others, a visual inspection, a CT scan, a weight and dimensions determination, and an internal resistance measurement.

Step Two: Cell Opening

Using precise methods, we open the cell without damaging its components. All steps and findings are thoroughly documented.

Step Three: Diagnosis and Post-Mortem Analysis

After disassembling the cell into its components, we use our expertise to assist you with fault analysis.

If necessary, we use our wide range of post-mortem analysis methods to analyze your cell components in detail.

We can prepare fault analyses for you on short notice
