Peak Nano Secures New Patents for Capacitor Film Technology

In a significant technological breakthrough, Peak Nano has announced the acquisition of two new U.S. patents that will enhance its leadership in the high-performance capacitor film market. Established in Valley View, Ohio, Peak Nano specializes in polymer nanoscale metamaterials, focusing on applications across multiple sectors including power grids, electric vehicles, fusion energy, and defense. These patents are pivotal for bolstering U.S. supply chains, especially in light of increasing competition from international counterparts.

The first patent (#US12427754B2) protects Peak Nano's innovative High Dielectric Constant (HDC) film, which has been meticulously engineered with surface modifications optimized for metallization. This cutting-edge design allows for tighter winding, making it easier to integrate into wound metallized capacitors. What sets this film apart is its capacity for energy density, boasting an impressive four times higher energy density compared to current state-of-the-art biaxially oriented polypropylene (BOPP) films. Consequently, engineers can create capacitor banks that can be made twice as small, thereby significantly reducing costs and simplifying design complexity.

The second patent (#US12119180B2) relates to the Low Dissipation Factor (LDF) film, known for its ultra-low loss and high-temperature resilience. This film minimizes self-heating and thermal stress, which can otherwise shorten the lifespan of capacitors. Remarkably, the LDF maintains its full energy capacity at temperatures up to 135°C—far exceeding the 85°C limit imposed by traditional BOPP films. This breakthrough reduces the necessity for cooling systems and enhances reliability in heavy-use environments such as fusion reactors and data centers.

As Dr. Michael Ponting, Peak Nano's Chief Science Officer, points out, the new patents mark a generational leap in capacitor film design. By removing the limitations found in legacy materials, these sophisticated polymer films enable superior energy storage and extended operational lifespans. The end result is a smaller and more efficient footprint for clients, which translates into practical benefits for various high-demand applications.

In the face of competition, particularly from China—which ranks as the top country in filing patents for grid technology—Peak Nano's latest patent is a crucial step toward reaffirming U.S. innovation and energy sovereignty. The expanded intellectual property portfolio is poised to foster new licensing and co-development opportunities, enhancing confidence among OEMs and potential buyers to consider U.S.-made alternatives.

With a growing collection of over 20 global patents and planned commercial deployment in early 2026, Peak Nano is at the forefront of advancing high-performance metamaterials for capacitors. This progress is not only crucial for enhancing energy independence but also pivotal for strengthening the resilience and security of America’s power grid.
