What is EMU

EMU (Electrochemical Measuring Unit) is a compact, modular solution for detailed analysis of batteries, supercapacitors, and materials — including measurements under real operating conditions.
EMU is an advanced electrochemical measuring unit designed for detailed characterization of batteries (BT), supercapacitors (SC), and materials used in their production.
It enables real-time monitoring of electrochemical processes while simultaneously applying pressure and temperature, which are continuously measured during operation.

Key Features

  • Conductivity measurements (EIS, CA)
  • Determination of ionic conductivity
  • Galvanostatic cycling of batteries and supercapacitors
  • Cyclic voltammetry and other electrochemical techniques
  • Full cell measurements
  • Parallel pressure and temperature monitoring
  • Three-electrode configuration (2 working + 1 reference electrode)
  • Measurement of solid, powdered, and liquid samples

Unique Advantages

All-in-one solution
Replaces multiple standalone instruments and covers a wide range of measurements.

Compact and practical design
Dimensions approx. 60 × 60 × 110 mm ensure easy handling, operation, and storage.

Unlimited modularity
Customizable dimensions and materials based on user requirements.

Efficient and error-resistant workflow
Interchangeable cartridges minimize errors, save time, and reduce costs.

Lower operational costs
No need for multiple devices or full system replacement in case of damage.

Interchangeable Cartridges

  • One-position insertion → eliminates incorrect handling
  • Replace only the cartridge, not the entire unit → significant cost savings
  • Parallel workflow → measure and prepare samples simultaneously
  • Custom electrode/contact materials (e.g., copper, stainless steel) based on conductivity, cost, or corrosion resistance requirements

Advanced & Expandable Functions

EMU can be delivered in a basic configuration or extended with:

  • Pressure sensor – monitors volume changes of the sample
  • Temperature sensor – tracks thermal changes during operation
  • Heating element – enables controlled temperature variation

Additionally:

  • Powder pressing into pellets (pressure > 30 MPa)
  • Separator testing (ionic permeability)
  • Supercapacitor parametrization

Applications

  • Development of materials for batteries and supercapacitors
  • Electrochemical measurements using galvanostat/potentiostat
  • Corrosion testing of metallic materials
  • Sensor analysis
  • Fuel cell research

Thanks to its chemical and mechanical resistance, EMU is also suitable beyond energy storage applications.

Who is EMU for?

  • Research institutions (universities, academies, research centers)
  • Companies in the energy sector
  • Materials and R&D laboratories
  • Small companies (including small-scale production setups)

EMU brings flexibility, accuracy, and efficiency to modern electrochemical research.

The EMU team

EMU was developed by an expert team from the Faculty of Materials Science and Technology (FMT) and the  Nanotechnology Centre CEET, building on the REFRESH and MATUR projects.

The lead designer is Ing. Ondřej Mušálek, who was involved in testing and development of the device, the design of measurement methods, preparation of documentation, and specification for the patent application. The project was initiated and is led by prof. Ing. Vlastimil Matějka, Ph.D., who provides expert consultations in the field of measurements, coordinates activities, and co-defines the patent specifications. The team thus combined expertise in materials research and electrochemical processes to develop an innovative and flexible measurement solution.

Other team members:

  • Oto Mušálek (CNT, currently also FMT) – Design of the structural solution and construction of the EMU; specification for the patent application.
  • Lukáš Plesník (CNT) – Testing and development of the EMU, preparation of documentation; specification for the patent application.
  • Gražyna Simha Martynková (CNT) – Coordination of activities, consultation on measurements; specification for the patent application.
  • Vratislav Mareš (FMT) – Design and implementation of force (pressure) measurements, technical documentation; specification for the patent application.
