Profile

LITRONIK is one of the few suppliers of compact, ultra reliable primary batteries for active implants anywhere in the world. Since 1990 the company has developed and manufactured these high-performance energy sources in a variety of performance ranges, and they feature, among other things, very high volumetric energy and power densities, rate optimisation, low self-discharge rates and high operating safety.

LITRONIK supplies customer-specific solutions as well as standard products to a variety of manufacturers of pacemakers, defibrillators and neurostimulators, both within and outside of Europe.
The electrochemical systems behind the primary batteries at LITRONIK are based on Lithium-Iodine (Li-I), Lithium-Manganese Dioxide (Li-MnO2) and Lithium-Carbon Monofluoride (Li-CFx), and they cover three performance ranges for different active implants:

  • High Energy Batteries with Li-I technology for implantable pulse generators, e.g. pacemakers or neurostimulators
  • Medium Rate Batteries with Li-MnO2 or Li-CFx technology for implants that require mid-range pulse power, e.g. pacemakers, neurostimulators or monitors with telemetry functions
  • High Power Batteries with Li-MnO2 technology for implants that require the highest pulse power, e.g. defibrillators

The batteries are manufactured in special dry conditions with a high level of automation. All processes are MES integrated. Materials and processes are 100 percent traceable.

LITRONIK uses its extensive expertise in electrochemistry, materials science, powder processing, metals/plastics technology, plasma and laser welding as well as various chemical and physical analytical processes in order to continually develop more compact and more powerful batteries and thus to enable ever more miniaturised implants.

LITRONIK is certified according to EN ISO 13485:2016. Every employee is fully aware of the high standards of quality required for life-sustaining implants.

Located in Pirna, Germany, roughly 20 km southeast of Dresden, LITRONIK has five production facilities with a total floor space of 5600 m2. The firm currently has approximately 350 employees.

Quality

LITRONIK’s quality management derives from the requirements of life sustaining medical implants. Its integrated and process-oriented system assures the highest reliability of the batteries and 100% traceability of processes and materials.

Every employee's activities are highly focused on customer requirements plus the quality and reliability of all products and services. Continual improvement of all processes, ongoing training and further education as well as the careful and efficient use of all resources are further cornerstones of the uncompromising quality policy of LITRONIK.
LITRONIK power sources provide today’s state-of-the-art in battery technology for implantable medical devices. The batteries are manufactured within a tightly controlled atmosphere to ensure highly reproducible electrical characteristics.
A completely laser welded stainless steel or titanium case and a high-precision metal-to-glass feedthrough guarantee hermeticity and safe operation.

Key characteristics of LITRONIK batteries include:

  • Very high volumetric energy and power densities
  • Rate-optimised (µA, mA, A)
  • Maximum reliability
  • Long lifetime
  • Low self-discharge
  • Highly reproducible electrical characteristics
  • Hermetically sealed stainless steel or Titanium housing with glass-to-metal feedthrough
  • 100% electrically, mechanically and visually inspected
  • 100% traceability of all processes and materials

Technology Development Secondary Batteries for Active Implants

The project aims the basic assessment of rechargeable battery technologies as well as the definition of development trends to build up a series manufacturing for rechargeable batteries for medical implants in humans. The challenging disciplinary problem underlies in the high requirements for the rechargeable batteries as there is a significant distinction from market known batteries such as for automotive or consumer electronics (e. g. smartphones).
As result of this technology study a demonstrator or prototype shall be presented, which fulfills the desired requirements and accordingly shows suitability for application in medical implants.

This project is funded by the EU via European Regional Development Fund. The project starts on 30.12.2019 and ends on 31.12.2021
