Peak Nano

Valley View, Ohio – October 12, 2026 -- Peak Nano has secured two U.S. patents for dielectric capacitor films that it says deliver four times the energy density of current biaxially oriented polypropylene (BOPP) film and hold full capacity up to 135°C, versus the 85°C limit of industry-standard BOPP.

Patent US12427754B2 targets smaller capacitor banks with a multilayered HDC film

The first patent covers Peak Nano's corona-treated multilayered High Dielectric Constant (HDC) film. Its surface modifications are optimized for metallization, tighter winding and integration in wound metallized capacitors.

The company says the nanolayer architecture delivers four times higher energy density and greater stability than state-of-the-art BOPP. Engineers can design capacitor banks up to two times smaller, cutting cost and system complexity.

Valley View – – October 12, 2026 -- Peak Nano has secured R&D funding from the Greater Akron Polymer Innovation Hub to develop nanolayered biodegradable multilayer polymer films for food, beverage and medical packaging, one of eight projects selected from more than 40 regional proposals.

Peak Nano targets hard-to-recycle multilayer barrier films

The Ohio company aims to replace conventional multilayer packaging film, which can contain many tightly bonded layers of polymers and additives that are difficult or impossible to recycle. Over time these materials fragment and shed micro- and nanoparticles into soils and waterways. Peak Nano says its alternative will keep barrier performance intact while being engineered for biodegradability.

Valley View, Ohio – October 12, 2026 -- Peak Nano has launched NanoPlex Films as a Service (FaaS), a design, prototyping and low-rate manufacturing platform that delivers working nanolayer film prototypes in as few as 6-10 weeks, compared with the multi-year timelines of new polymer development.

The platform targets medical, food and beverage packaging, power systems, electronics, aerospace, defense and industrial customers. It is built on Peak Nano's patented NanoPlex technology and what the company describes as more than 60 years of nanolayer systems formulation and processing expertise.

Valley View – October 12, 2026 -- Peak Nano and E&P Technologies have formed a strategic partnership to co-develop high-energy-density capacitors built on Peak Nano's NanoPlex HDC dielectric film, targeting fusion drivers, aerospace and aviation systems with million-shot duty cycles.

E&P selects NanoPlex HDC as the base for a new capacitor class

E&P Technologies chose NanoPlex HDC as the foundation for capacitors designed for fusion drivers, pulsed power systems and demanding aerospace and aviation environments. Peak Nano arranges multiple polymers in nanoscale configurations. Compared with traditional polymer dielectric films, the company says the result is higher energy density, improved thermal stability and enhanced electrical reliability.

Valley View – October 12, 2026 -- Peak Nano and Advanced Conversion, a wholly owned subsidiary of ETI of Clearwater, Florida, have formed a partnership to co-develop DC-link capacitors for 800V+ e-mobility, with initial product releases slated for late 2026.

Engineering teams from both companies are already developing joint products. The partnership is structured for long-term co-development across passenger EVs, commercial vehicles, off-highway platforms, electrified aviation and DC fast-charging infrastructure.

Valley View – October 12, 2026 -- Peak Nano's NanoPlex LDF film holds 95% of its room-temperature breakdown strength at 135°C and handles 25% more current than traditional film at the same voltage and temperature, without derating. Advanced Conversion has selected it as the dielectric for its new HP Drive Test Kit, a DC-link inverter solution for 800V+ Silicon Carbide (SiC) power electronics.

Advanced Conversion is a wholly owned subsidiary of Electro Technik Industries (ETI) of Clearwater, Florida. The companies describe the kit as one of the first fully domestic DC-link solutions for high-voltage e-mobility. Target platforms include Formula E and performance automotive, electric buses and heavy trucks, off-highway and industrial vehicles, and electrified aviation.
