Highest quality

CUSTOMCELLS® Tübingen – outstanding performance of the highest quality

Cells of the highest quality that meet any standard – that is the aim at CUSTOMCELLS® Tübingen. We are committed to products ‘made in Germany’ with our developments and our production processes. Even in the development stage of new cell formats, quality-related aspects have a direct impact on our production methods. Quality is an integral part of all processes at CUSTOMCELLS® Tübingen. When it comes to quality, we are constantly thinking one step ahead. 

The highest production tolerances are made possible by advanced technologies with laser processes. The technologies – which are partly developed by our process engineering team – can guarantee virtually burr-free cutting and careful handling of the materials.

The right choice of materials

The best materials, the most reliable suppliers – producing a high-quality cell starts right at the very beginning. The choice of material and supplier is an important step for being able to guarantee the quality of the entire product. 

We always take responsibility for the materials used in the battery cell production process and are committed to ensuring that they are of the right quality. By taking regular samples prior to use, we constantly make sure that the materials meet our high standards.

Testing processes firmly rooted within the company

CUSTOMCELLS® Tübingen monitors every stage of production. We use both in-line and offline testing methods as an integral part of our quality gates. End-of-line testing enables us to check the open-circuit voltage, internal resistance, self-discharge rate and capacity of the cells, among other things.

We systematically check incoming goods, inspecting them to make sure that all raw materials meet the specifications. To this end, we use a wide range of common measuring instruments that are constantly monitored and subjected to a measuring equipment analysis before being used for the first time. During the production process, we continuously check compliance with all key characteristics, monitoring the precision of the laser cut, for example, or the water content after the electrodes have been dried.

We subject all of the data from the testing processes to statistical evaluation. In conjunction with close collaboration within the company, this allows to guarantee and even improve the quality. We are driven by a continuous improvement process.

The Principles of our CUSTOMCELLS® Quality Policy

Customer satisfaction

You as our customer are our most important asset and therefore have top priority. For our complex projects or products, it is essential that we listen carefully to you as a customer in order to implement your needs and expectations. Only in this way are we able to implement the solutions individually tailored to your project in such a way that they meet your needs (including budget, delivery times, time frame, services/products, sustainability). Our goal is to achieve lasting customer satisfaction. We can only achieve this by offering products and services that fully meet your actual needs.

Compliance with legal requirements

It is our goal to manufacture products that permanently meet the requirements and expectations of our customers. To this end, we develop and use processes and manufacturing equipment that are in line with the state of the art in science and technology. All production and testing phases are carefully planned and subject to compliance with all required standards and regulations as well as national and international legal requirements.

Continuous improvement

Through permanent and continuous improvement processes, measures to increase the quality of our products and services are identified and their implementation is given top priority. All organizational, commercial and technical processes are constantly reviewed with the aim of avoiding errors and increasing efficiency. In order to continue to meet the growing needs of the market in the future and to set ourselves apart from our competitors, we are constantly developing new products and services and taking them to the desired level of maturity. We have set quantified quality targets to ensure this continuous improvement process.

Employees and managers

Our employees are our greatest strength. Their sense of responsibility is constantly encouraged and trained within our system. One of our most important tasks is to keep our employees' skills and know-how up to date. We aim to support this by constantly improving the working environment and providing regular training. It is the task of the management staff to realize the quality goals of CUSTOMCELLS®. Through personal example, open, honest communication and the involvement of employees in decision-making processes, the personal responsibility and quality awareness of our employees are promoted.
