High Power Density Capacitors for High Temperature Navy Applications

Advanced power systems for Future Naval Capability depend on capacitor banks as the first stage of pulsed power. Significant electrical energy is necessary to support a range of applications including electromagnetic armor, electromagnetic gun and electro-mechanical aircraft launch systems. In order to ensure successful integration of these technologies, capacitors with reduced size and weight must be developed. The focus of the proposed commercialization pilot program (CPP) is the scaled manufacturing and demonstration of high energy density dielectric film for wound capacitors. Dielectric formulations will be based on TPL¡¯s polymer and/or nanocomposite formulation. The prior Phase II SBIR focused on a nanocomposite system consisting of fluorinone polyester (FPE) polymer and TPL¡¯s titanate nanopowders. The proposed program includes three areas of focus; film optimization, scale of film manufacturing and capacitor fabrication. Tasks for each development period will be performed sequentially in six month increments and include specific milestones, performance targets and deliverables. The overall objective of the program is to establish manufacturability and demonstrate the energy density capabilities of TPL¡¯s polymer film in sub-scale capacitors. Wound film capacitor sections will be fabricated and evaluated relative to system level performance specifications. TPL anticipates this energy density, relative to full-scale capacitors for Navy pulse power applications, to be ¡Ý 3.5 J/cc.
