    Rheinmetall and Polycharge announce joint venture to commercialise innovative capacitor technology for electric mobility

    As part of its electrification strategy, the Düsseldorf-based tech enterprise Rheinmetall is setting up a joint venture with the US start-up PolyCharge America to produce, develop and market DC-link capacitors.

    Underlying this move is the group’s goal of gaining a stronger foothold in the rapidly growing markets for emobility and industrial applications, as well as accessing subsystems and components necessary for making innovative products in future.

    In this constellation, Rheinmetall is responding to the growing demand for emobility and green energy components, especially in the automotive parts sector but also from its military customers.

    In the Rheinmetall PowerPack system for electrical vehicles (EVs), now in development, advanced DC-link capacitors from PolyCharge play an important role. Owing to its improved efficiency and range, Rheinmetall sees strong market potential and scope for growth for the new power pack solution.

    In this close operational partnership with PolyCharge, the joint venture will have exclusive rights to produce and market NanoLam capacitors in Europe. To underpin its close cooperation with PolyCharge, Rheinmetall has simultaneously taken up an approximately 13 percent share in the Tucson, Arizona-based company.

    Rene Gansauge, Rheinmetall’s Sensors and Actuators division chief executive, said: “The founding of this joint venture marks another important step in our transformation strategy, enabling us to offer our customers in the automotive and industrial sector top electrification technology as we move forward.

    “Advanced NanoLam technology lets us offer a product that’s substantially smaller and lighter than the conventional solutions, and which can operate at higher temperatures.

    “This is a clear technological advantage, assuring that Rheinmetall PolyCharge is well positioned to meet the growing demand for these technologies.”

    The new PolyCharge capacitors with nanolaminate technology feature sub-micrometre-thin, dielectric polymer coatings that enable optimum cooling and improved performance.

    PolyCharge is a technologically leading supplier of these components, whose chief advantages are thermal stability, longevity and high output density. In future, the activities of the majority joint venture will be based in Rheinmetall’s Sensor and Actuators division, which is spearheading the company’s electrification strategy and now implementing advanced developments in the “Beyond Automotive” and industrial domain.

    Steven Yializis, PolyCharge America COO, said: “Diversifying PolyCharge’s manufacturing base is crucial as we transition to high-volume production of NanoLam capacitors for automotive, aerospace, and industrial markets.

    “Rheinmetall’s technical depth, application expertise, and strong presence in Europe make it an ideal partner, allowing for rapid expansion in this important and growing market.”
