Inline Microbattery Testing at TDK/Epcos

From Lab Bench to Production Line

When TDK/Epcos prepared to scale manufacturing of their first of their kind CeraCharge™ microbatteries, they faced a familiar but critical challenge:

The impedance testing procedures developed in R&D, while effective, relied on high-end laboratory potentiostats that weren’t designed for scale.
Sequential testing couldn’t meet production speed.
High-end systems were too bulky and expensive per channel.
And the microbatteries needed not just testing, but complex, multi-step conditioning in parallel and inline.

And then they met us!

A Fully Parallel, Scalable Solution

Sciospec collaborated closely with the test engineering team to design a 512-channel potentiostat/galvanostat system specifically built to:

Perform real impedance spectroscopy on each cell
Handle conditioning cycles per unit
Operate fully parallel, matching the battery tray layout
Integrate smoothly with robotic handlers and automation systems
Maintain lab-grade precision at production speeds

Ready to scale your own high-channel testing setup? Talk to our experts to find the right fit for your production environment.

In R&D, we used a high-end potentiostat great results, but impossible to scale for the channel counts needed. With Sciospec, we achieved lab-grade impedance testing at full parallel throughput, integrated directly into our automation line. No other platform could have delivered this combination of performance, cost-efficiency, and integration-readiness

Technology Foundation

This system is based on our scalable potentiostat/galvanostat platform, tailored for high-density parallelization.
The full technical details and specs of this base system are available on the dedicated product page

Built for Production. Inspired by the Lab

This project is a prime example of what Sciospec does best:
Taking research-grade test concepts and turning them into scalable, production-ready systems — without compromising on accuracy or flexibility.

If you’re working in electronic component testing, from R&D screening to high-throughput inline QA, we have the tools and experience to support you.

Start Small, Scale Big

For those just beginning to explore impedance-based component testing, Sciospec also offers standard, easy-to-use LCR and impedance analysis tools like the LCR-3 system designed for benchtop use, prototyping, or lab-scale QA.

These tools feature:

Broad measurement ranges (mHz to MHz)
High accuracy
Modular port configurations
Compatibility with our multiplexer and adapter ecosystem

They’re the ideal starting point, and they’re built on the same platform that powers our most advanced OEM systems meaning you can scale up when you’re ready without changing core technology.
