The legal entity and its main tasks

Infineon Technologies AG (IFAG), Neubiberg (Germany), combines entrepreneurial success with responsible action to make life easier, safer and greener. Barely visible, semiconductors have become an indispensable part of everyday life. Ranked one of the global top 10 semiconductor companies, it plays a key role in shaping a better future – with microelectronics that link the real and the digital world. IFAG’s semiconductors enable efficient energy management, smart mobility, as well as secure, seamless communications in an increasingly connected world.

IFAG designs, develops, manufactures and markets a broad range of semiconductors and system solutions. The focus of its activities is on automotive and industrial electronics, communication and information technologies, IoT, sensor technology and security. The product range comprises standard components, software, customer-specific solutions for devices and systems, as well as specific components for digital, analogue, and mixed-signal applications. IFAG organizes its operations into four segments: Automotive, Industrial Power Control, Power & Sensor Systems and Connected Secure Systems.With 54 research and development locations and 20 manufacturing sites the company is active worldwide with approx. 46,700 employees. In the 2020 fiscal year the total revenue amounted to €8,567 million.

Tasks and justification in INSTABAT

IFAG will contribute to the project primarily by developing semiconductors and MEMS for battery applications, with an emphasis on direct & indirect sensors. A summary of the activities in which IFAG is going to participate is given below:

  • WP1: IFAG will lead the specifications and requirements work package.
  • WP2: IFAG intends to develop, improve, manufacture and test smart micro-sensors to measure the CO2 concentration inside of Li-ion battery cells. In addition, IFAG plans to improve, manufacture and test reference electrodes for the determination of working electrode potential during battery operation.
  • WP5: IFAG will support the partners to enable the processing of data from all sensors considered within the project, for usage in battery modelling, battery virtual sensing, and the battery management system (BMS).
  • Other minor contributions: Besides the specific contributions mentioned above, IFAG will contribute its fair share to the tasks of exploitation, dissemination and general project management.

CV of the persons

Dr. Thomas Roessler

Infineon, 85579 Neubiberg, Germany

Dr. Thomas Roessler: After completing his physics studies with a PhD in Theoretical Solid State Physics at Arizona State University (Tempe, USA) in 1997 and an appointment as post-doctoral research associate at the University of Tucson, he took on several positions in R&D related to CAD, photomask design, and design for manufacturability in the semiconductor industry in Munich. Between 2010 and 2019, he worked in the photovoltaics (PV) industry in various assignments covering the value chain from solar module manufacturing to project development for commercial and industrial PV power plants (including electrical storage). In April 2019, he joined IFAG as Senior Manager with a focus on the acquisition and coordination of multi-million funding projects in the areas of power electronics and the sensorisation of batteries.
