Battery Facility Upgrade Completed in Berlin
Chem4Batteries is pleased to announce the successful commissioning of the latest hardware upgrade of its in‑house battery facility in Berlin, Germany. This milestone marks another important step in strengthening our technical capabilities and underlines our continued commitment to fast, flexible, and high‑quality battery development services.
With an investment in the range of double‑digit kEUR, the upgrade significantly enhances our speed‑to‑market, flexibility, and service depth for customers operating in demanding and regulated application environments. The expanded infrastructure further reinforces Berlin as a central hub for controlled battery research, benchmarking, and prototyping within Chem4Batteries’ global development network.
Flexible Electrolyte Filling as a Core Capability
A central highlight of the upgrade is the commissioning of a new flexible electrolyte filling system. The system is designed to handle pouch and cylindrical lithium‑ion cells in parallel, enabling a level of flexibility that is essential for modern battery development programs.
This capability allows Chem4Batteries to support customers across multiple development stages—from early‑phase benchmarking and electrolyte evaluation through to prototype and small‑series production—without being constrained by cell format. By integrating this system directly into our Berlin facility, we ensure that critical cell assembly steps remain fully under controlled, in‑house conditions.
High‑Integrity Benchmarking with Data Generated in Berlin
The upgraded facility enables high‑integrity benchmarking with all experimental data generated exclusively in Berlin. This provides customers with a reliable and transparent data foundation that meets the expectations of professional R&D, industrial qualification, and program‑driven development environments.
Customers benefit not only from validated benchmarking results but also receive the tested cells themselves for downstream evaluation or system integration. At the same time, Chem4Batteries combines strict in‑house process control with high quality and cost efficiency, supported by its experienced manufacturing partner network in Asia. This hybrid approach ensures scalability without compromising data quality or development speed.
Advanced Electrolyte Engineering for Challenging Environments
Beyond benchmarking, the new infrastructure significantly expands our capabilities in electrolyte engineering and cell customization. This enables targeted electrolyte studies and bespoke cell designs for challenging operating environments where standard electrolyte formulations reach their limits.
Such environments may include extreme temperatures, specialized load profiles, or application‑specific performance requirements typical of autonomous systems, UAV platforms, and security‑related technologies. By designing and validating customized electrolyte systems, Chem4Batteries helps customers optimize cell performance, durability, and safety beyond conventional off‑the‑shelf solutions.
Rapid Prototyping Across Multiple Cell Formats and Packs
Speed remains a decisive factor in battery development. The facility upgrade directly supports rapid turnaround times for battery prototypes, covering pouch cells, cylindrical cells, and complete battery packs.
Integrated processes—from material preparation and mixing to electrode handling, electrolyte filling, and cell assembly—allow rapid iteration cycles and fast learning curves. This enables customers to move efficiently from concept to validated prototype, significantly reducing development timelines and project risk.
Small‑Series Supply for Mission‑Critical Applications
In addition to prototyping, the upgraded Berlin facility supports a reliable supply of hundreds of cells per month for specialized, low‑ to mid‑volume applications. This capability bridges the gap between laboratory prototyping and large‑scale manufacturing, addressing the needs of programs that require controlled, repeatable small‑series production.
Such supply volumes are particularly relevant for unmanned autonomous vehicles, advanced robotics, and defense/security‑related systems, where quality, documentation, and performance stability are often more critical than sheer scale.
A Platform for Flexible and Controlled Battery Development
With this upgrade, Chem4Batteries further strengthens its position as a partner for flexible, controlled, and application‑driven battery development. The Berlin facility combines hands‑on engineering expertise, robust laboratory infrastructure, and an international partner ecosystem—enabling customers to advance battery technologies efficiently and responsibly.
If your programs require flexible battery prototyping, advanced electrolyte development, reliable benchmarking, or tailored cell supply under controlled conditions, we look forward to connecting and exploring how Chem4Batteries can support your development goals.
